Debugging display textures

Is there any way to debug the source of glass displays not showing up in the
model? like the texture entry in the panel cfg not matching any material etc?
I can’t seem to trace why my displays are not showing in a new model even
though I have confirmed material names and parts and UVs are all matching up.

What are the material settings of that display? Is the emissive color set to
white (255, 255, 255, 255)?

Make sure you have sequentional material IDs, e.g. 1 2 3 4 5, not 1 2 3 4 7 -
this can happen in a sub-material is removed and the IDs not updated. It will
cause the assigned display/poly to simply remain invisible.

Where do I find these?
