PointSet raytracing colors defects

Development
1

I have raytraced many particle datasets in the past with great results. Up until ParaView v6.0, I used to compile ParaView with OSPRay v3.1. I don’t use materials, only scalar field coloring.

Trying ParaView v6.1, I made an attempt to switch to OSPRay v3.2, but my colors are wrong (all greenish). I am including an OpenGL rendering as reference to show the whole scalar range of my particles’ field (note that I use logarithmic colormap scaling). My raytraced image (with shadows) with OSPRay 3.1 is good and my last option is unfortunately all green…

Have other users out there seen similar color defects?

Is Kitware contemplating supporting an upgrade of the OSPRay layer? I seem to understand that the binary released and build by the Superbuild still use OSPRay v2.12

In fact we just updated to OSPRay v2.12 in our release binaries. There is an MR to switch to OSPRay v3.1, but it has not bubbled up to the top of our priority list. We are currently focused more on ANARI integration in ParaView for ray tracing going forward.
