How to recreate shapekeys movements in bone form for roblox rig

I’m trying to import the JCThornton Mickey Mouse Model to roblox but the issue is the platform doesn’t support shapekeys so i wanna know how i can recreate the shapekey movements in bone form so they can be imported to roblox i tried adding driver bones to the mesh and baking animations but i didn’t see the bones appear or the animations in the animsaves. can anyone tell me how to turn shapekey movements into bones movements for my rig without vertex deformation?

It depends on what you do.
For bones that you use for controls, I suggest you disable deform, and then when exporting, make sure to

Instead of shape keys, you can use bones and A LOT OF WEIGHT PAINTING AGONY.

If some of the bones don’t load on Roblox, that means that they probably have 0 influence

Also suggest disabling Auto Normalize and fixing it all manually through WeightNormalize per each bone selection manually.

i don’t understand this idea could you clarify?
