Collect USD Look Assets errors if lop graph errors and fails to cook

[BigRoy]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior:

When a Look product type is being published it will collect the used textures/materials from the USD graph - however, if that graph fails to cook (has errors) then the collector will error. However, the error itself isn't clear to the user.

If LOP graph errors the LopNode.stage() call errors without any clear details.
This is e.g. noticable in the Collect USD Look Assets

Expected Behavior:

We may be better of presenting a clearer PublishError that describes what most likely the issue is.

Version

1.0.0

What platform you are running on?

Windows

Steps To Reproduce:

1. Create Houdini LOPs network to publish Look product type with
2. Make the selected LOP path unable to cook (e.g. enforce an error in the LOPs graph above it)
3. Publish.

Are there any labels you wish to add?
