I just encountered an annoying bug when assigning materials to objects:
I import the same object (feet.glb) 4 times and alias them as feetFrontLeft, feetFrontRight, feetBackLeft, feetBackRight. Each alias has its own position/scale.
When assigning (on load or on click) a material to each alias (object by object, or get object from a list with objects), only one alias is actually showing the material.
The workaround I found, was making 3 copies of feet.glb (feetFL.glb, feetFR.glb, feetBL.glb) and importing those as feetFrontLeft, feetFrontRight…….

Had to fix it another way. The geometry in the copied files still had the original name. (feetFL.glb still contained the geometry called ‘feet’). I set up the copies in blender with unique names, and exported these.

all of them are not meshes. they are scenes (or groups of objects). you cannot assign materials to scenes. it’s possible only with meshes. moreover, meshes from those scenes must have unique names to be interactive. otherwise you can assign materials only to meshes from the first scene.

Puzzles and JS. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of meaning at all.
