BIM is supposed to make things easier and more efficient, right? Then why do we often have to re-do work in different platforms, simply to get the result we want? Surely, we can do better… especially when it comes to high quality rendering and presentation workflows.
One common scenario is that you might export a Revit model to some 3D editing and animation software, perhaps like 3dsMax. Then, you will do some work, modify materials, tweak some lighting perhaps, and then render an image. That image might go into Photoshop where additional Entourage and effects are added. And you do get a kind-of good result. But, what if you change the model? Well, you have to go through multiple steps just to update things. Or, what if you want to take the nice material from Photoshop and bring it back to Revit? That can be a real pain. However, now there is a better way…
I have written about Lumion a few times before. It is a incredibly powerful tool for Architects to present and share designs. However, it may still have suffered a little from the ‘endpoint syndrome’ described above. But that is no longer the case! Now, Lumion offers a Live Link to the Revit model, meaning that work does not have be done over and over again.
After Lumion starts, you will be prompted to start a new scene from the scene templates:
In just a few seconds, it launches showing your Revit model. Seriously, it is really fast! This workflow is so much quicker than an export – import method, and will be familiar to users some of the other popular realtime visualisation solutions out there. You can immediately start navigating in this rendered environment. And of course, you can start building your Lumion scene by adding content from the immense library. However, we really want to focus on LiveSync. How does it work?
Here is a list of some things that work really nicely:
you can move objects in Revit, and they immediately move in Lumion
you can add new objects to Revit, and they will show up in Lumion
you can edit Revit materials, and they will update in Lumion
delete an object in Revit and it disappears from Lumion immediately
you can use terrain tools in Lumion to merge in with your Revit topography
I have created a short video that describes how to get up and running with Lumion 7.3 and LiveSync for Revit. Check it out here:
Further, this new Exporter provides a much tighter integration between Revit materials and Lumion materials:
After you have completed an editing and model building session with LiveSync, what happens next? Well, you can close Revit and Lumion, and Lumion will prompt you to save. It does actually save the embedded LiveSync object. So, later, you can open Lumion and do some scene development work without using Revit.
How smart is this connection? To test it out, I did this:
opened Lumion 7.3
opened a scene that included a LiveSync model
then, I opened Revit with the appropriate Revit model
for some reason, it didn’t update… until I realised that the LiveSync model uses the File Name and Path to determine which model it came from. Because I had used ‘Save As’ on that Revit model and put it somewhere different, the link was broken. I then used a Revit model in the correct location, and Lumion immediately updated the import
This means that using a Revit model in a consistent location will allow easy updating of the Lumion model. You can work independently in Revit or Lumion, and then at any time restart LiveSync to updated the model in Lumion with the changes from Revit. Nice!

Video – Moving Objects
Video – Editing Materials
Video – Settings
It is interesting to note that Lumion materials are essentially ‘disabled’ for LiveSync Revit objects.
This makes sense of course, because we are trying to keep as much intelligence as possible in Revit, and leverage the strengths of Lumion for high quality outputs.
If you find that your Revit model is ‘too low’ and embedded into the Lumion terrain, you can globally move it, just as you would with other Imports:
Items in worksets that are closed or invisible by default will not show. What this basically means is that the Lumion LiveSync addin does not work on the specific objects you can see in the current Revit view, but rather it works in a more ‘complete’ sense, showing all objects that would typically be visible in any view.
If you are already using Revit and Lumion, these new additions will make designing much easier and more efficient. If you haven’t used Lumion before, now is definitely time to try it out! This improved connection to Revit, along with the already powerful content creation capability of Lumion, will truly allow design and present in ways you have never even imagined!

Design is a funny thing. The word itself carries a certain weight, it is somehow deliberate and exciting at the same time. Yet, so often design is let down by the poor translation or communication of ideas. You may have an excellent ‘design’ in your mind, but displaying or presenting that to a client is an entirely different matter. Every designer faces the same challenge of communicating their design ideas in a thoroughly engaging way: whether the communication be to their clients, other stakeholders or even as part of their own internal design process.
This is a site about Revit, but this article is about discovering new possibilities, new ways to express your design, new ways to add context, realism and reality. It is also about a powerful piece of software called Lumion– a design communication tool that I personally use and have used for quite a few years. Thecombination of Revit and Lumion give architects a complete toolkit for modeling, understanding, sharing, adjusting and presenting their design.
So, what is Lumion? Recently, I was speaking to the Chief Operating Officer of Act–3D, (the parent company of Lumion), Roger Hammond. He told a me a very heartening story about the development of this piece of software…
Often we don’t immediately recognise the full potential of a new, beautiful idea. Roger describes that Lumion was initially designed to be a powerful presentation tool, but Architects soon discovered that it can also shift the way they design in very positive ways. He describes how a new user of Lumion can easily get comfortable with the basic concepts of the software, even those who are not ‘technical’ or especially comfortable with computers. Yet, once they start using Lumion, they get to grips with it easily and quickly learn to iterate design changes and brief clients more rapidly and smoothly. Lumion gives a certain realism and context to your design that can assist you to modify and improve the design internally, before it is even time to present it to anyone.
We often become so used to a way of working that we almost feel like there is no other way, or that perhaps we already have the best way. Yet, if that were true, innovation would not be a reality. Sometime, disruption is necessary. So if you have an established way of designing and communicating, take this opportunity to re–evaluate as I reviewLumion.
The user interface itself is nice and clean and easy to read and understand. As someone used to complicated programs like Revit and AutoCAD, this is a welcome breath of fresh air to me. Rather than present you with an overwhelming and detailed set of buttons, Lumion allows you to progress your digital presentation in stages, from Building to Materials and Lighting and Presenting and so on.
In this way, the development of your design and your presentation output can be very logical and layered. You can import your design from a variety of different programs and platforms (like Sketchup and ArchiCAD, not just Revit), and once imported you can add people, trees, and soft and hard landscaping. You can sculpt the site topography and add water and grass areas. Once you feelcomfortable, you can dig deeper, modify lighting, adjust materials, add special effects, work on camera angles…
And finally, you can display your design in some truly simple yet beautiful and intuitive ways. The key thing is not to be afraid. You can’t break things in Lumion, it is not a imposing or complicated environment. Navigation is straightforward, nothing is very complicated. As you use it, extra functionality will reveal itself. It is a tool that has been built for designers, and its development has been shaped by their feedback. Roger recalls that it is not uncommon for users to say that “Lumion has changed my business”, and there are plenty of ‘wow’ moments. For example you can add the ocean to your scene with just one click…
We have experienced this realisation at Virtual Built. Recently, we have been demonstrating Virtual Reality tools to our clients. However, in some programs it can be difficult to populate a scene quickly and then output to a suitable VR platform. This is not the case in Lumion, as the included content means you can get up–and–running quickly. If you have a few basic building models, you can add site context and a few nice little details like a truck or a crane to create a site utilisation model, and then output to a number of different VR panoramic formats.
I have been using Lumion over a number of years and different versions, so I was excited to see theupdates and new features available in Lumion7. The major new features are listed below, and we will dig into each feature and uncover the new opportunities they present.
Lumion7 New Features OpenStreetMap (OSM) is an online resource that stores 3D building models along with map information like roads and water areas. In the past, I have used many methods to try to get a locality plan or model created, and it can be quite clunky and challenging. However, in Lumion7, this is now completely automated. Using the OpenStreetMap import, in just a few minutes you can have a realistic map in Lumion to locate your building models, and it will even have adjacent 3D building models as well! It will automatically ‘cut out’ your own building model from the OSM data. The OSM function in Lumion7 is still Beta functionality, but it can already be very useful to quickly add context or a background to your design.
To get started with OSM in Lumion, just:
Start Landscape mode (left side flyout menu) and turn the OSM switch ‘On’
Click the Longitude / Latitude area to bring up a searchable map
Search for your location
Set the import Range and press Download
Tip: hold Shift + Spacebar and use arrow keys to move quickly on large sites
Check out this page for more information on OpenStreetMap and Lumion.
New Features for Weathering and Foliage
Building models sometimes appear ‘flat’ due to the way various platforms handle materials. However, in Lumion7 you can now remove the coldness of computer–generated imagery by seeking out edges, roughness and other properties of natural materials to make them look like they’ve been around a while. My associate here at Virtual Built, Michael Clothier, recently used this to add realism to an important theatre building in Adelaide that is currently under construction.
You can also cover models with leaves or add weathering, ageing and transparency. Even transform any object into thousands of leaves or add ivy to a wall… These tools are implemented through the Material Editor, so the workflow is logical but the effect is quite impressive indeed.
Here are some examples:
To get started with these tools:
Enter the Material editor
Select a object to change
Set a Material from theLumion Library, and double–click on it
In the editing pane, you will find the tools on the right…
Then, simply drag the sliders until you have the desired look and feel
Sometimes, the available Lighting tools in presentation software can be quite limiting. Happily, in Lumion7 you can now add light strips or area lighting, meaning you can go beyond simply ‘spot lights’. I really enjoy adding these new lights, because as usual they can be edited with sliders, and you can view theeffect in real–time… there is no need to wait for a lengthy rendering and then realise the lights were switched off 🙂
To get started with the new Light types, open the Object pane:
Then select the Area Lights tab:
Place the light and then modify the sliders until you have the desired effect:
You can use Lumion to share a navigable panorama to anyone who owns a smartphone. It is incredibly simple and powerful and is one of the features I hinted at earlier in the article. It is something that allows you to put your design on display in a new way, and get valuable client feedback and engagement. Then, you can quickly iterate the design and send them a new link.
We have used this to create sets of views for various stakeholders, but the key thing is really how easy and quick it is. You don’t have to print something or even save an image and find it on your hard disk. You can do all of this creation and sharing in just a few clicks. We have found it to be a real game–changer.
Summary There is no software program available that can automatically interpret a client’s design brief, provide suitable visualisations, interpret client feedback, and iterate this process while learning at each step. A good Designer can do this. But with the right tools, parts of that process become much easier. As a designer, you will be able to interpret the brief and interpret client feedback. With Lumion, you can quickly and easily present your design, in context, and in a multitude of rich, realistic, immersive ways. By thus improving the way you communicate and iterate your designs, you designs themselves will improve. And your client satisfaction level will soar…
So I recommend that you give Lumion a try. And be ready to be surprised 🙂
Guide 1: Using Lumion in Virtual Reality Workflows Lumion VR Lumion VR viewer is no longer supported, instead you can render static images for viewing on a variety of VR platforms. I will provide some notes on how you can do this below.
Using A Mobile App like PlainVR
Render VR Panorama images (these will be 360 degree jpg files). You can use default 64mm eye to eye and 360 slices
Embedding VR to a Website with VR View
Google has kindly provided a web service for rendering images in VR, its called VR View. After creating your stereoscopic image, you can follow these steps to embed it into your site:
Note: in Blogger, after you add an ampersand character to the code, it converts it to some other characters. basically, you can’t ‘edit’ after you input the code, if you publish it directly it won’t replace to & and it works…
Using Oculus with Lumion
To do this:
Render a 360 jpg file from Lumionthen
View it in a panorama viewing app, such as Oculus Photos

In times past, I had this dream that Revit would be the sole answer to every single architectural and modelling question. Due to the proliferation of excellent addins and addons, I now realise that Revit is positioning itself as the operating system of the BIM environment. It has a solid parametric, data and intelligence engine, which can be extended in many ways through the expansive API. One area in which Revit has sometimes wavered is in pure visualization, particularly of the real-time and photorealistic variety. Using RPC and Realistic display modes within Revit can achieve a certain result, but here are some questions:
Is using an additional presentation package, like Lumion, worth it?
Will it result in a better visual result?
Will the performance be acceptable?
I received a review copy of Lumion 5.3, and tested it using Revit 2015 Update 7. As usual, I have reviewed the software, but at the same time I am sharing practical tips and guidance on how to get up and running with Revit and Lumion.
To start with, let’s consider whether Lumion can really add value to your current design and development pipeline. You may be thinking “I don’t have a clue how to make a fly-through animation“, but that is where Lumion lives. It makes it easy for you to take your BIM geometry, and put it into a real, living environment. In a sense, it is a ‘complete’ visual presentation package, as it includes things like environments, backgrounds, materials, weather effects, water, entourage, vehicles, people, trees, landscape, furniture, terrain modelling, and it is all in a package that allows you to modify, manipulate and tweak basically everything in real-time. It has a clean UI and extremely fast rendering capability. For output and deliverables, you can easily export still images or rendered videos of the scenes that you have composed.
You might be thinking “I don’t have time to learn yet another modelling tool“, but if you spend any time at all in post production software like Photoshop, 3ds Max, After Effects or something similar, then Lumion does not represent a steep learning curve. The interface is relatively unobtrusive and simple to understand. The Lumion addin allows for building models to be exported from Revit, but it also allows models to be updated and reloaded into the Lumion scene. As one person put it, “Use Lumion and Revit together and you will enjoy the synergy.”
You can check out a very concise ‘getting started’ style video here:
To put it simply, when you pair a powerful and parametric building design tool like Revit, with a free-flowing, smooth, flexible presentation software like Lumion, you have a very formidable design and presentation pipeline at your disposal. So, let’s learn a bit more about Lumion…
This remainder of the review has been divided into the following 5 sections:
Download, Installation and Deployment
Workflow (BIM friendliness)
Quality of Output
Real-world applications and Case Studies
Download, Installation and Deployment: Installing the Main application
You will receive an activation email, with a unique download link
Download and run the ‘download manager’
Copy the activation code from your email to the download
It will now automatically download Lumion, usually to your Downloads folder (about 4.94gb)
You should copy the installation .exe and .bin files to some safe location – these are what you will use to install Lumion on other PCs
The installer should run automatically – all you need to do is set the install path
Start Menu – Run Lumion 5.3
Agree to the Licence Agreement
Lumion will now run some benchmarks and initialize itself
Once the next screen appears, you will get a ‘system speed’ rating
Note: I was expecting to see a Revit addin automatically installed… but I have since realised that this is an additional step… see below.
Examples of cards with about 2,000 PassMark points: GeForce GTX 745, Quadro K4000M, GeForce GTX 570M or faster.
Harddrive: 20GB of disk space
Using Lumion and Lumion Pro via Remote Desktop or similar virtual desktop solutions is not supported.
Lumion and Lumion Pro require an internet connection.
Workflow (BIM friendliness)
There are a number of ways to move data from Revit to Lumion, such as using DAE format via Exporter, or FBX via built-in export. The dedicated DAE exporter addin from Revit is the recommended method.
The Exporter addin (Revit to Lumion Bridge) works in orthographic 3D views and takes all visibility filters for the view into account. If you try to export from a Perspective view, the Lumion export addin will be disabled. However, in Revit 2015 R2 you can easily convert a Perspective 3D view into an orthographic or Parallel-3D View to allow export to proceed. Here’s how:
Ensure that a Crop Region is applied and Visible, and the view is “unlocked”.
Then, right-click on the View Cube and switch to Parallel-3D view, like this:
Then, run the exporter. The UI is relatively easy to follow:
I tested using ‘normal’ accuracy, and the file size result was like this:
You can then easily open or create a scene in Lumion, and then import the model you just exported from Revit:
Once in Lumion, you can use the WASD keys to walk around, and QE keys to move up and down. If you hold the right mouse button and drag, this will change your view direction. Holding Shift will speed up your movement. It is quite a fluid navigation system. F1/F2/F3/F4 turns shadows on and off and makes other quality vs performance changes.
Click the category (people, transport, landscape etc)
Click Change Object to select desired model
Click to place in the scene
To bring in external models, like DAE or FBX exported from Revit, use the Import models option.
Depending on how your model heights were configured in Revit, you may need to move your model downwards in Lumion. In my case, I had to move the model downwards in the Y-axis by about 150m (yes, Lumion understands the vertical to be the Y axis, not the Z):
To update the model, just re-export the DAE file from Revit. You can reload by: going to Import mode, selecting the spanner for ‘context’ menu, selecting your Model and then clicking on the blue circle, which will open up the context menu with the reload option:
It is interesting to note that even new objects (ie. newly added to the Revit model) that have a Revit material name matching a currently overridden material in Lumion, will then adopt that Lumion material when the import is reloaded. Nice!
There is a brief tutorial video on the Lumion to Revit workflow here:
So, is Lumion able to do anything that Revit can’t do? In a word, yes. For example, it can handle things like sculpting large-scale terrain models very easily, as this demo shows:
Add to that: movie effects, ocean / water, the large model and material libraries, lighting effects, render quality, and the overall ability to transform a scene from a collection of polygons into something that more effectively represents the real world.
The Collada DAE export was very, very fast – under 1 minute for a 150mb Revit model. Accordingly, of all the file types that can be used to get data from Revit to Lumion, I would expect that the recommended and preferred method is via the DAE export in the free addin.
Quality of Output
Lumion is targeted at rapid, real-time, moving animations with models that may also be animated. So the result is usually something that looks very ‘alive’. Coming from an architectural background, you may initially be surprised at the overall ‘look’ of things and you might find it slightly cartoonish. However, I recommend that you give it a try and have a go at tweaking a few of the display settings.
It is very easy to create a flythrough or fly around animation. Just start the movie tool with the film icon, then create a number of keyframes as you would with other animation tools. Then, you can easily export to mp4.
Real-world applications and Case Studies
I tested using a medium rise model:
Once the model was imported, it was very easy to select entire materials and replace them with more appealing versions:
To delete models, you can remove them directly from the library and they will disappear from all scenes that they are currently placed in. However, you can also delete the model only in the scene you are currently working on, and it will remain available in the library for use in other scenes:
Children´s hospital with more than 15,000 plants and trees
Summary of Lumion 5.3
In review, let’s consider some of the questions raised at the beginning:
Q. Is using an additional presentation package, like Lumion, worth it? A. Yes, it would be very difficult for plain Revit to deliver the same speed, quality, and content
Q. Will it result in a better visual result? A. When it comes to real-time scene export, a Lumion visualization can be much more alive and animated than a Revit equivalent. You can also easily deliver your scene as a selection of high quality images, or as a rendered video.
Q. Will the performance be acceptable? A. Yes, provided you have a decent CPU and graphics card (refer to requirements above)
Summary of each section:
Download, Installation and Deployment – 7/10, necessary to manually install addin
Workflow (BIM friendliness) – 8/10, support for updating changed models
Performance – 8/10, much improved in more recent versions and fast export to DAE
Quality of Output – 9/10, smooth and appropriate for the visual style
Real-world applications and Case Studies – 9/10,
(see links above to see how companies are using Lumion)
My overall software score for Lumion 5.3 is 9/10.Its definitely worth a look if you do any kind of presentation work with 3D models!
In a future post, I want to look at the large-model workflow from Infraworks to Lumion via FBX. Other links, tips and resources
If you migrate your work from earlier Lumion versions take into account that the material system has been changed in Lumion 5. This requires you to re-apply the materials to your objects.
If you select option “Skip Interior Details” then these Revit Categories are skipped:
How to delete objects? You delete imported objects by using the Imported Objects Library. It cannot be deleted from the Library if you have a scene open and using that object, so first clear and start a new empty scene.
Then in Build Mode click on Import button –> Change Import Object –> locate your object to delete and doubleclick the Rubbish bin. That will permanently remove the object from the library and the files.
Editorial note: “In the interests of editorial disclosure, I would like to note that this review was completed with some financial consideration from the developers of Lumion. Luke Johnson”
Information related to older versions
I have been familiar with Lumion for some time. A full scale Lumion review has been on my radar for a while, but like anything, it takes time to have a proper look at a piece of software.
My past experiences with Lumion had been hampered by less-than-stellar hardware. You really do need a decent workstation to have a fluid and productive time with Lumion. In my case, my new workstation at Virtual Built has 64gb of RAM, a 6 core (12 hyperthreaded) processor, and a Quadro K4000 video card.
If you want to sign up to test it, email email@example.com with subject Fuzor Evaluation.
