Skinned Mesh FBX Animations Don't Import

[DopePersonHasProblem (Aiedail)]

Hi everyone!

I imported a FBX skinned mesh arms with animations into Roblox using the avatar importer. The animations import and work find for all but one of the parts in the FBX. That part doesn’t receive the proper animations. I opened the FBX with Blender, but the animation still works there. Is there anything I’m doing wrong?

How’s the gun rigged to the arm? Looks like it’s not rigged in correctly.

What do you mean? I just imported it with the avatar importer, which automatically uses motor6ds to attach everything to the root part. The gun just doesn’t have animations.

The gun is not moving. It seems that its not rigged correctly.

Okay, good to know. How do I fix it and rig it correctly? Sorry for my stupidness, I don’t usually rig stuff.

Sorry, but I can help you on that. But here is a video that I found:

Blender How To Attach Objects With Vertex

If that is what your looking for.

Thanks! However, the animation works fine in Blender. The gun is attached to the hand and everything, but only when I import it to Roblox does it stop working, so I think that its a Roblox problem not a Blender one.

Skinned MeshParts are live!

Basically, in case your question is similar to mine, the solution is to weightpaint everything including rigid parts if any (unless you’d prefer using attachments for these). Rigid parts get the full 100% weight to whichever bone it’d be applicable. (e.g shoulderpads could be the shoulder-bone) Non-rigid parts should be weightpainted more carefully, but most of the time you can automatically weight the right bit of the mesh to the corresponding bones in Blender. If something doesn’t appear norm…

Have you had any luck with this? There are numerous things to check. It looks to me that the bone the gun is skinned to is not loading (and thus it does not move), or that the gun is parented to, but not skinned to, the bone. Blender can handle parenting, Roblox cannot.
