Please note that there are several important limitations using the V-Ray GPU engine:
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 runs only on CPU which is the so-called hybrid rendering.
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 forced rendered with V-Ray Next Update 1 (4.10.x).
