OptiX Pathtracer rendering not similar to OSpray pathtracer when using custom materials
As reported on discourse (see this topic https://discourse.paraview.org/t/optix-ray-tracing/2198), when switching OptiX in 5.7.0-RC2, the rendered image does not look the same at all compared to what OSPray pathracer produces.
I attach my materials library, and two state files with their respective data to reproduce the problem.
