[MTOA-34] USD Camera prim bug with Arnold

[jcoelho88]

Hello,

I recently updated the plugins we are testing with and have noticed that the Arnold Render View does not seem to recognize the USD camera prims, they default to something called "defaultUfeProxyCameraShape" and if you try to render through it you will get this error:

// Error: [mtoa] Setting camera defaultUfeProxyCameraShape failed // 

Here is what I'm using:

• Windows 10
• Maya 2022.2
• Arnold MtoA 5.0.0.1
• Maya-usd 0.13.0

Steps to reproduce:

• Create a stage with a new layer.
• Create a Camera prim (see pictured)
• Open the Arnold render view and try to render (you will notice the USD camera prim was renamed)
• Check script editor for error

In earlier version of the plugin I think 0.11.0 or 0.12.0 this was not an issue that I encountered.

The expected behavior is for the scene to render from the USD camera prim. If there is some kind of incorrect configuration of plugins please let me know. If this is a known issue, is there a way around this? Should I wait for a fix or possibly revert to a previous version?

Any assistance with this would be greatly appreciated.

Cheers,

Jason Coelho
