Hi,
OK here’s a more elaborate render. The trick is how to adjust color and opacities profile. Used 150 samples + denoising.
For more massive sciviz examples with Blender, see also this presentation: https://www.youtube.com/watch?v=eiRO6vqZRUA
PS. Since Cycles is also a stand-alone render engine, you could theoretically incorporate it into VTK/Paraview. That might require some serious work, though, I’m guessing.
BR,
Tuomo
