Greetings,
I was trying to do some ray trace rendering, but I am missing the option for ‘Enable Ray Tracing’ in the view settings. Also in the material editor shows “OSPray support not available”. Any ideas?
PV client info is pasted below. Thanks!

MacOS binary release simply does not support raytracing afaics.

The macOS binaries provided on [www.paraview.org/download](http://www.paraview.org/download) _do_ support ray tracing.
@caladoa from where did you obtain the binary?

Ah, I missed the M2 in the OpenGL Renderer. We do not enable OSPRay on arm64 binaries for macOS.

Just a note that OSPRay being disabled in ParaView’s mac binaries is a legacy from a few years back when the “new” arm Macs came out and OSPRay had not yet been ported to run on them. Current OSPRay does support arm, so it _could_ be made to work by someone adventurous enough to try it.

Is there any update to this as of 2025? Ray tracing seems not to be available with version 5.13.1 on Apple M3.

Hi @aleksandrShukman, that’s interesting. I have tested ParaView 5.13.1 downloaded from [www.paraview.org](http://www.paraview.org) on both M1 and M4 macs and OSPRay ray tracing is available and works.

I just tested my M1 Macbook with 6.0.0-RC1. Ray tracing is available and works. I will say it’s subtle - ray tracing and non ray tracing looks the same. I changed the ambient intensity, and then I saw a change. I also tried shadows, that also works.
