PxrTexture breaks when material node has colon in name

[breadbyte]

Steps to reproduce:

1. Open blender.
2. Select the default cube.
3. Add a RenderMan nodetree to it. I used PxrDisneyBsdf as the material.
4. Add a PxrTexture node as the base color.
5. Add an image. It should appear.
6. Add a colon to the material name.
7. Change the image. Any changes to the image will not appear.
8. Remove the colon. An image must be set again for it to appear.

Thanks for the report. We're currently using the material name as part an ID for the texture manager. Clearly this won't work if you rename the material. We'll have to come up with a better strategy for creating an ID for each texture in the texture manager.

I believe I have fixed this issue. Unfortunately, this is too late to get into the upcoming 24.3 release, but it will be available once 24.4 ships.

I just synced to the latest in master and I can see the issue when rendering with Blender 3.0. The issue still happens whenever the material is renamed.

@fxjeane Yes, the fix will be in 24.4. Currently, I don't have an ETA of when that will ship, unfortunately.

I see. The issue is with PRMan, and not on the Blender add-on?

[prman-pixar]

Yes, it's a problem with some of the core python modules in PRMan.

This issue should now be considered fixed with the release of RenderMan 24.4
