Hi there,
I was looking to apply some material textures to my .stl model and thought OSPRay might be the solution but Paraview 5.7 does not show any OSPRay heading. Screenshot attached.
This may sound really silly, but try scrolling down? When I just selected Ray Tracing, a whole section of the properties tab appeared below “shadows” .
It is in the advanced options. Click on the gear icon.
