Character Customization - Bone Parenting Error?

Hi, I'm trying to make character customization for my RPG. I have a character, that I deleted all parts of except the head. So they have an animated skeleton, but nothing on it.

I have heads, and armor, with a matching skeleton (minus the parts that weren't needed, hair didn't need arms or legs) that I parent to the main skeleton, to have customization.

So for the hair, the prefab had parts from my FBX export, like sun, camera, lamp (via blender). I deleted these, and am now receiving the following error: [mecanim]: BindSkeleton: cannot find Transform 'Sun' For every part that I deleted.

I was told to set the animation type, for the hair import, to None.

Upon doing this, I get three issues. First of all, the hair doesn't appear to render anymore. Secondly, there are two errors:

• Number of bind poses doesn't match number of bones in skinned mesh.

• SkinnedMeshRenderer requires a mesh with skinning or blendshape information.

I have no idea what to do. The hair seems to be "upset" about how I deleted the camera and leftovers from the blender export inside it. How can I fix this?

Thanks, I tried to be as detailed as possible, Ruk
