Bug: Can't access material data from graph

[hybridherbst]

The attached graph should log properties from this file: NumberCube.glb.zip

However, it seems that the current object model implementation doesn't allow that.

I think this should log "true":

{
    "nodes": [
        {

I have added materials into the KHR_interactivity world references to access the materials properties of the model alongside most of the core materials pointers which I could find Babylon js mappings for. One thing I did notice is that your pointer is also incorrect /materials/{index}/pbrMetallicRoughness/baseColorTexture/roughnessFactor -> /materials/{index}/pbrMetallicRoughness/roughnessFactor

Thank you! Would you mind adding KHR_texture_transform as well? That's what I was originally trying (and thus the pointer error here)

[mattmacf98]

just added them
