Hello there. I’m having the same issue 1 as you.

I Can’t figure out what the problem is. Have tried with large renders and on a test, simple render with a couple of materials. It renders fine in CPU only mode, but as soon as I activate the GPU acceleration the finished render is totally different, much darker and some of the materials qualities change totally …very strange indeed.

I have tested it on different computers and the same thing happens. I have searched google and I can’t find anything about this issue until I read your post. Would appreciate any ideas to fix this extremely annoying problem. Thanks in advance.

I’m using Vray 3.4 on sketchup pro 2017
Windows 8.1, Xenon cpu and asus 1060 gpu
