What other resources can you look at to learn about Lumion?

Please look at the following resources to get started:


Can you install Lumion on a Mac?

Lumion is not available on OSX, and there are no plans to make Lumion available on OSX. Parallels and WMWare Fusion are also not supported.


However, if you install Windows on your Mac via Bootcamp, you can install Lumion on the Windows partition. Please note that the latest Nvidia/AMD driver must be installed, otherwise you may not be able to run Lumion.


Important: Using Lumion on Macs is not officially supported. Act-3D provides no warranties on any of the functionality in Lumion and does not accept any liability claims arising from the use of Lumion on Macs.


Please also note that Macs often do not have very powerful graphics cards and will struggle when running Lumion. Please click here to check if your Mac's graphics card is suitable for Lumion.


Upcoming versions of Lumion will not be available on Mac


Does Lumion support 'remote desktop' access?

No, Lumion does not officially support 'remote desktop' access, for example via Windows Remote Desktop, WMWare Fusion, VMWare VDI, Citrix/ZenApp, Teamviewer, Nvidia GRID, XenServer, XenDesktop etc.


There are currently no plans to add support for any of these applications.


Some 'remote desktop' applications such as TeamViewer might let you start the rendering procedure but navigating around scenes and moving objects etc won't work as expected. Other 'remote desktop' applications such as Citrix and VMWare products will have trouble running Lumion.

Why does rendering sometimes take very long?

Rendering times will increase if your scene is 'too complex' and your hardware isn't powerful enough and/or lacks free memory. 'Too complex' refers to the following variables:

  1. The number of different models you've added to the scene.
  2. The 3D Points number in the top right corner of Build mode.
  3. The number and resolution of textures/materials.
  4. The Movie/Photo effects you're using.
  5. How many reflection planes you've added in the Reflection effect.
  6. How many Spotlights that are set to Shadows -> Accuracy in the scene.
  7. How many Spotlights you've selected in the Global Illumination effect.


To reduce the time it takes to render an image of a clip, you should try to reduce the number of all of the above. In particular E, F and G.

How does background rendering work in Lumion?

Lumion always renders movies and image sequences in the background (which correspond to the MP4 and Images tabs in Movie mode), so that you can check your emails etc while it is rendering. Background rendering is not supported when rendering a still image via Photo mode or the Single tab in Movie mode.


IMPORTANT: Please follow these instructions when you render videos or image sequences to ensure that the background rendering process works as expected:

  • Do not switch to another program until the first image is done rendering.
  • Do not move/re-size/minimize the Lumion window.
  • Do not bring up the Task Manager.
  • Do not click on the Show Desktop button in the lower right corner of Windows.
  • Do not let Windows return to the Windows login screen or the screensaver (see below).
  • We recommend rendering MP4 files on a local harddrive.
  • If you render an MP4 file on a network drive, please ensure that it is a mapped drive and that you can access it via an Ethernet cable (not via WiFi). If you are uncertain about rendering an MP4 on a network drive, then please render it on a local harddrive on your PC.

Failure to prevent any of the above from happening will cause Lumion to lose the connection to the graphics card and will reset the exposure and shadows in Lumion when rendering is resumed which means that the video has to be rendered from scratch again. It may also result in corrupted MP4 files.


If your PC switches to the screensaver or to the Windows login screen after a few minutes, rendering will also be interrupted. You can prevent this from happening by running the Windows Media Player in the background, e.g. with playback of a few songs set to repeat.
