Limitations of GPU rendering in Specular materials?

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)

GPU doesn't support sss right now as far as I remember...

Correct, SSS on GPU is missing. Support for it will be added soon though.

Hi there,

any news on the implementation of SSS for GPU Rendering?
