Converting BMD to .dae and then .dae to BMD only keeps first set of UV coords

[RenolY2]

When you convert a BMD to .dae and then convert the .dae to BMD without importing it into a 3D modelling program first, UV coords for layers beyond the first one are omitted by SuperBMD. Example are the pollution models in Super Mario Sunshine:
pollution01.zip

Importing the .dae into a 3D modelling program and then exporting as dae or fbx does not have this issue and SuperBMD correctly reads the additional UV layers. (Tested with Blender 3.2.0, should be the same with other Blender versions)

Unconfirmed if this is the same issue as #7 (both are fixed by importing into a modelling program but unsure if #7 is caused by missing UV coord layers.)

I have this problem too but with Delfino Plaza map.bmd and other levels.

I've had this same issue with converting .bdl files from Wind Waker into .dae and then into .bmd. It'll remove the UVs for the toon shader texture. Would love to see a fix for this soon. It'd also remove the second material color as well.

The way I was able to look at the models was using GameCube File Tools and it'd tell me all sorts of info like materials etc.
