IPR Debug Shading selection in C4DtoA 4.2.0 does not work on GPU

[skx555]

With GPU as Render Device, the IPR Debug Shading selection in C4DtoA 4.2.0 does not work - neither the basic utility AOVs nor the custom ones. Adding them as a Material does work on the GPU. It has been like this for a long while now, but I think to remember that it once did function correctly on the GPU?

Please see attached Video for proof & GPU vs CPU Log - it shows that utility:/debug|utility and  AiWireframe aren't loaded on GPU.

It's a limitation, I'm afraid. Shader overrides, which required by the debug shading feature of the IPR window, are not yet supported on the GPU.
