It does not look like anything changed there.

This could also be achieved with the new GeomPropValueUniform node which was added to materialx last month. Is there a timeline yet for when this could be added to houdini?

GeomPropValueUniform will be available in the next version of Houdini.

My current solution is to create a "Material Library" node and add a MaterialX Shader Builder node for each sub-mesh.

Or if you want to have two levels deep, then you should be able to put down a subnet inside the LOP, and put the material builders inside it. Then point to them in the LOP's parameters to create USD materials.
