Overview

...

Chaos Cloud supports and renders scenes using both the V-Ray CPU and the V-Ray GPU engines. Chaos Cloud supports V-Ray GPU rendering running on CUDA and RTX enabled devices.

Please note that there are several important limitations using the V-Ray GPU engine:

  • Version V-Ray 5 and onwards: all submitted V-Ray GPU jobs are rendered with Progressive mode! It is recommended to use Progressive mode when submitting jobs to Chaos Cloud, as it runs faster than the Bucket mode.

  • For V-Ray Next and prior versions: V-Ray GPU runs only in Bucket mode! Any V-Ray GPU Progressive scene will be forced to render with the default Bucket mode sampling settings if no prior Bucket adjustments are done to the scene. If any Bucket adjustments are done in the scene, regardless of whether Progressive is chosen afterwards, Chaos Cloud will use those Bucket settings. We recommend using the Bucket image sampler when submitting a scene for rendering in GPU mode in order to keep greater control over the render settings and quality. V-Ray GPU 5 supports Progressive mode.

  • Chaos Cloud supports only versions V-Ray Next Update 1 (4.10.x) and above for V-Ray GPU, i.e. any V-Ray GPU scene created with a previous version will be rendered with V-Ray Next Update 1 (4.10.x).

typeinfo

V-Ray GPU jobs are rendered with GPU devices, but submitted scenes should not exceed 16 GB of GPU memory. Else, the jobs fail. In such cases you can use the CUDA CPU Override option and re-render the job using only CPU.
