Problem with Skinned MeshParts

So skinned MeshParts are now live, and according to the topic, it says only the AvatarImporter will import skinned MeshParts, but it doesn’t talk about how to convert a current MeshPart into a skinned one.
I have a custom character in Roblox, and there are still gaps in the kness. I also tried the same thing with the basic Rthro Character Oliver and there still are gaps.
Is it currently possible to convert it? If so, how?

Probably because skinned meshparts are for skinned rigs. It doesn’t transfer over to regular roblox avatars.
