vray RT vs vray COLOR CHANGE

[morean]

Hi,

I'm trying to render a simple interior scene to compare render times and quality between CPU rendering and VRayRT GPU CUDA (both version 3.00.07).

The output in both situations seem to be different in terms of saturation and light intensity:

With CPU:



With GPU (600paths, but even with 1600paths looks the same in terms of coloring):



I'm using a GTX Titan Black with the las NVidia drivers (337.88 ) and the same render settings and camera for both renderings.



Does anybody have the same problem or knows the solution?



Thanks!

The RT version has less number of GI bounces (3 by default), you need to increase them to get the same result as in the production renderer.
