So I have many many models. Each has a skeleton, material, etc. I want to take some of these and combine them into one so I can apply animation commands to one rather than many (and so they stay in sync). I have one mesh, say MeshA with the following hierarchy: MeshA -AllJoint -AllTrans1 -Take 001 -MeshA Take 001 being a sample animation clip MeshA being the mesh MeshB is similar in hierarchy however has the same bone structure (down to every detail). MeshA is a body, and MeshB is arms. I want to "stich" MeshB into MeshA so that I can apply animations to MeshA and have MeshB work.... Currently, I just create a base object, put MeshA and MeshB under it, and apply animations to them individually (it gets really tedious with more than just these 2, specially when the animations get out of sync or I want to do blending). How do I "stich" these 2 together as it says in the Unity2.1 features?
