Hi Yulia S, I’m not on the development team, I just make assets and tutorials. From what I’ve seen in discussions on the official Discord server, it sounds like there are no plans to add deformation. This makes sense when you consider that the meshes export as quads instead of tris, and quads don’t handle deformation very well. This is a change they could potentially make, but I don’t see any evidence of it happening soon. One workaround you could do is to rig and animate, then export a DAE file for a program like Blender. You could potentially convert the bones from simple “parent” types that move the objects to traditional “envelope” type that morph the model. But at that point it would probably be easier to just export the model alone and rig in Blender from the start.
