Shape key set at 0.5:

Puzzles and Blend file:

Those faces in verge3d is black when shape keys set at 0.5, yet when it increases, it switches to its intended color. Why?

HealthBar Frame’s shape key at 0.5:

After increasing shape key:

How do I prevent the unwanted black color? Want these faces to be its intended color

Even if I change shapekey to 0 in Blender, and reupload blend file as gltf, the object at shapekey 0 is at desired color – just that when it becomes 0.5, it becomes messed up black

do both shape key objects share the same color?

If you mean both the green and grey bars, no, they do not share same color.

a little more accurate modelling (without overlapping in geometry) can do the trick…

Puzzles and JS coding. 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 the meaning at all.

kdv, thanks for your answer, it gave me an idea to simply adjust the relevant vertices’ location for shape key value 0, after issuing new shape key value. It works. I learnt a lot from your answer as a byproduct.

Btw, do you know how to activate individual clones in a list, only when certain conditions are met? Problem is, when one clone in list is activated, other clones do not trigger even though conditions are met for other clones as well

that’s because your are using one global variable for all clones. After the first clone changes this variable the condition won’t be met for all other clones.
