[Max][glTF] Problem when multiple textures (pointing to the same image) has different transform

[Ben-Mack]

In a scene with multiple textures pointing to the same image, but each one has a different transform value, then gltf output will be wrong (same transform value on these textures). Babylon format output is correct, please see these screenshots:

Original file in Max, left plane has tiling value of 1.0, the right plane has tiling value of 2.0, both pointing to the same image:

Result in babylon format ✔️

Result in glTF format ❌

@Ben-Mack working on a fix

@Ben-Mack just merged a fix for this: https://github.com/BabylonJS/Exporters/blob/master/3ds%20Max/Max2Babylon-1.3.17.zip

Thank @kcoley for very quick update!
But the problem still exist in the latest version v1.3.18, can you recheck it?

[kcoley]

@Ben-Mack interesting, sure I'll double check. Do you have a sample max scene that repros the issue?

[kcoley]

@Ben-Mack I tested with this node network:

I was able to get this result:

Though I assume your scene setup is authored differently from this or I misunderstood your description?

Yes, my material setup is different.

This issue will occurs if you use StandardMaterial (work fine on PhysicalMtl though).

@Ben-Mack I just made another update, which should now allow StandardMaterials to export. Let me know if you hit any other issues!

[Ben-Mack]

I confirm this issue is solved. Thank you!
