3d max Skin Mesh Bug

[Selective]

As usual, I attached the body parts to each other, but this series did not work properly and a bug was created

It looks like your Skin modifier might not be affecting all of the skin's vertices. What kind of skeleton is this - is it CJ or a regular ped skeleton?

Ok, sorry I think I missed the end of your video.

When you attach new mesh to a skinned object, Max will try to weigh each new vertex to random bones nearby.
What you can do is import a new character with similar mesh. Select all of its vertices, then attach your custom character to the imported model. With all of the vertices of the other skin selected, press delete. Now only your custom character's mesh is left and it should be glued to the bones a lot better.
