So ik this isnt rly a Lua question but its not too off topic, it deals with CharacterMesh.

I was looking through models of npcs and noticed some that used packages from the catalog like this http://www.roblox.com/The-Overseer-item?id=81725506

but my question is how do i use character mesh to make my own NPC's like this. I applies a Character Mesh to a generic NPC but idk where to get the MeshID and TextureID for each part (Legs/Arma/Head)

If this isnt a good question for this site admins feel free to remove it i understand.
