Sync render and proxy

[wandth]

When an asset has usd's proxy and render prupose,
when the proxy is rotated and scaled in the maya viewport, only the proxy purpose is changed, and the render purpose remains unchanged. Is there any way to make the two changes synchronously other than callbacks?

There is a feature in USD called proxyPrim, which is used to link a render purpose prim to a proxy purpose prim, to match pruning and transforming between the two:

rel proxyPrim = </Car/proxyMesh>

However, I'm not aware of any Maya USD features that currently accomodate this. In Houdini however, it is possible to use a configureprimitive node to set a Proxy Primitive for the selected prim.

Edit: Sorry, it seems that also Houdini has not implemented proxyPrim to work this way. It's currently just there but doesn't have any real functionality associated with it (yet). Hopefully in the future.
