Limitations of GPU rendering in Specular materials?
Posted: Sat Jul 28, 2018 2:04 am
Hello,
I am going to render a scene where a wax candle is part of the center piece so realism is important.
I found 2 different "Wax" materials in the online material database and they look really nice, using CPU rendering that is.
With GPU/OpenCL instead of wax it looks like cast resin (highly transparent).
Is there any way to get a result similar to the CPU with the GPU? Is it becasue of SSS?
Material used in below renderings is White Candle Wax by Whaat https://www.indigorenderer.com/materials/materials/120
Version is Indigo RT v4.0.66, Windows 64-bit build.
Rendered in a few second with GPU (GTX 1080)
Rendered in 20 minutes with CPU
