Reparenting a proxyshape?

[pierre-ed]

Hi everyone.

Here I go again :) with yet another painfully simple question: is reparenting a proxyshape under another transform supported?

My current testing scenario is pretty straightforward: I load a mayaUsdProxyShape using Create->USD->Stage From File, and then reparent the created proxyshape under an existing transform using cmds.parent(proxyshape, new_parent, shape=True, relative=True). This operation triggers no error, but the proxyshape vanishes from the VP2 renderer (even after a call to cmds.refresh(force=True)).

Internally, computations seem correct however, since my proxyshape reappears with the expected transform when I switch renderer to the GL Hydra render delegate.

Am I missing something? Is there a workaround to force the refreshing of the scene or render delegate behind the vp2RenderDelegate?

Thanks in advance for your insight.

Hi Pierre,

I believe this is a Maya bug with re-parenting shapes that have MPxSubSceneOverride's attached. If you run an ogs -reset the objects should re-appear. @santosd I can reproduce this one locally, will you convert to an issue something internally for us? As a work around re-parenting the transform above the proxyShape should work fine.

Thank you, William.
The viewport refreshing command you mentioned works like a charm. :)

Great! A word of warning, ogs -reset is quite slow for complicated scenes. So if you do find more places you need to use it for correct behavior please keep reporting them.
