PathOCL bug with Split RGB/Combine RGB nodes
Posted: Sun Jul 07, 2019 12:20 pm
When I tried to change a bit a colour of texture using Split RGB and Combine RGB node (in PathOCL+Sobol) I've get an error ending with:
In Path+CPU+Sobol all works well.
When I disable Split/Combine RGB nodes and use the base texture colour it works on both CPU and OCL modes.
LuxCoreRender version - v2.2beta2
Error raises both in Blender and in standalone version.
In attachment image:
1) colour I want to get
2) material node setup that works CPU only
3) render with Path+CPU+Sobol
4) error when I try to switch to PathOCL in blender
5) material node setup without using Split RGB and Combine RGB node
6) render with PathOCL+Sobol
