FAQ – V-Ray for SketchUp


I'm I eligible for the free upgrade to V-Ray for SketchUp 3.0?

If you bought your license after the 1st of November 2015, you are eligible for free upgrade. Contact your reseller for help.


I cannot start the V-Ray for SketchUp installer.

It's possible the installation file didn't download properly. This might cause your installer application to crash when attempting to run it. Please re-download the installation file from the Chaos Group website.


Does V-Ray for SketchUp support GPU rendering?

GPU rendering is supported in V-Ray for SketchUp, but currently, it doesn't support all available V-Ray features. GPU OpenCL render mode is currently not supported. GPU CUDA is available only for Fermi-, Kepler-, Maxwell- and Pascal- based NVIDIA cards.

For more information, see the Supported Features in Interactive Rendering page.


GPU Accelerated Interactive rendering with V-Ray for SketchUp takes a long time to start.

GPU Accelerated Interactive rendering with V-Ray might take a while to start up the first time you run it on a specific graphics card. Each subsequent start should be almost instantaneous, even after closing and re-opening SketchUp.

However, installing a new version of V-Ray or the same version of V-Ray on a new machine, or installing a new graphics card, will again take a while to start up, but only the first time after making such changes.

If you experience other problems with interactive rendering and GPU Acceleration, please contact Chaos Group Support.
