Cannot load materialx graph about blenderusdhydraaddon HOT 9 OPEN

@VascoPi please make a task to update to latest MaterialX

from blenderusdhydraaddon.

@bsavery
An approach without updating MaterialX version, adding a single file gltf_pbr.mtlx and generating mx classes work as well.

Here's the blend scene.
gltf_pbr_blend_scene.zip

Here are the files you need to put into BlenderUSDHydraAddon_1.1.1_Blender_3.1_Windows.zip before installing the addon.
gltf_pbr_materials.zip
copy gltf_pbr.mtlx -> BlenderUSDHydraAddon_1.1.1_Blender_3.1_Windows.zip\hdusd\libs-3.10\libraries\bxdf
copy gen_gltf_pbr.py -> BlenderUSDHydraAddon_1.1.1_Blender_3.1_Windows.zip\hdusd\mx_nodes\nodes\

2. Install blender 3.2
3. Enable
4. Import materialx
5. No change.
6. Cannot put material on the mesh in blender.

Hi,
The implementation of the glTF PBR material has been added since MaterialX 1.38.4 (Add glTF PBR #861)
Currently, BlenderUSDHydraAddon supports MaterialX 1.38.0.

Sure, here's the ticket.

Quick review.
I was successful in building HdRpr using MaterialX v1.38.4.
Importer and render (Full and Interactive) work well, at the moment no issue is observed.

A discussion with HdRpr devs is needed to update MaterialX version.

Can you post some instructions and sample blend project files?

I wanted to tell others this workflow works today without release, and whenever the version is updated, we can forward update.

@VascoPi When will this be in a new version of the BlenderUSDHydraAddon?
