I am testing Solaris on a very heavy scene. I am thinking of is there a way that I can display the geo in the viewpoint using a low res proxy for the purpose of set dressing. Then switching to a high res, when render in Karma ?

Scott talks about it in the H18 launch presentation, the workflow is shown on-screen:

I've also attached an example file.

You might also be interested in seeing if the Create LOD LOP can help you manage complexity.

USD accomplishes this with Purposes - Render, Proxy, Guide, and default. Set the dense meshes to Render and your proxy representation to Proxy using the Configure Primitive LOP. GL renderers draw Proxy, Guide, and default, while final renderers draw Render and default.

This is great ! Works like charm. Thanks.

Hey all, bringing this topic back up…

Just to confirm, this creates essentially two primitives in the scenegraph… one for the proxy and one for the render. How are people managing “redundant” primitives in the Scenegraph?

And secondly, if the renderable purpose is hidden from GL, is it still loaded into memory, or is only the proxy loaded into memory (until render time)?
