Standin - Viewport 2.0 GPU memory

Hi everyone,

I have a question regarding Standins in Viewport 2.0 when set to Shaded display mode.

They seem to use up significantly more GPU memory than a GPU cache. I've noticed that the "GPU Instancing" VP2 option helps slightly, but nothing in comparison to a gpu cache.

Is there anyway to get Standins lighter on the GPU without going to bounding boxes?

Second question: If the case is that Standins are just heavier. Does anyone know of a way to prevent gpu caches from loading into memory at render time? ie. keep them visible in the viewport but have no effect on ram usage.

EDIT: Okay, so it seems like the best option is to use your own proxy geo as a procedural and not use standins?

Thank you.
Andrew

1) afaik, standins don't do anything special for the GPU, not like a gpuCache. MtoA has to recreate the geometry based on what's in an ass file, so it's going to be "heavier" than a gpuCache

2) mtoa translates a gpuCache node to an alembic procedural node. The only way I see to avoid that is to turn the gpuCache into a template (Object Display > Template in the Attribute Editor)
