Hey, I want to second this. I was hoping this feature would be added in arnold 7 but it doesn’t seem to be there. It’s a shame because it’s a super useful feature when working in any heavy scenes.
It’s a little complicated for me to share a scene, but it’s reproducible in a simple set up with two spheres and a configure primitives LOP for each:
- Set the purpose of one sphere to be “proxy” and the other to “render”
- The sphere set to purpose:proxy will appear when you render the image, and the one set as purpose:render doesn’t even seem to be loaded.
- If I remove this “render” purpose from the sphere, it appears in the render again.
I’ve also noticed the same issue in the animal logic alab dataset ( https://animallogic.com/usd-alab/ ) which has assets set up with render and proxy purposes. From what I can tell, arnold is just bringing in the proxy purpose geometry as normal render geometry, and it’s completely ignoring the render purpose geometry.
