I’ve got a hand model I made in blender. I mirrored the hand as well as the armature and when I import this to roblox (Saved as fbx btw) It looks like this:
It seems to have mirrored bones but the model itself for some reason is not mirrored. The non mirrored hand imports just fine. This is what it looks like in blender (mirrored one is the left hand btw) :
I mirrored it by using Shift+D and then right clicking and mirroring it on the X axis.
I have tried making the size of the model inversed in blender using S+Y±1 but no difference.
