alembic GPU cache and V-Ray

[brobins]

Hi,

Have there been any developments on this front?

I am looking for a good workflow of utilising GPU Cache's and rendering through V-Ray as if it were a proxy. I need to be able to render and control multiple shaders in the caches / proxies.

V-Ray proxy works great until I need to see a full viewport representation of the model.



When compared to using a GPU Cache, system ram is far less consumed.



I'd love to find a solution that allows the best of both worlds. Off loading the Proxy display to the GPU would be perfect.

One of the nightlies made great improvement in using alembic as vray proxy, you can also specify a separate proxy file for display. It seems just as fast as gpu cache now.

There's now a new Maya bug causes me not able to use my custom gpu/vray ablemic proxy combo. Basically if you reference a gpu cache node the hypershade/graph editor will turn blank.

Hm, I can't reproduce this hypershade issue. Can you make a simple example?

The issue is with Maya referencing Maya's gpu node, not VRay proxy. We've already reported it to Autodesk.

If you want to try, just reference a Maya gpu node, open hypershade or graph editor, it'll turn blank.
