Hello there,
So I have a rigged character but I wanted to re-use the armature to avoid partly creating a new one. My question is does appending an armature and using it on a different model carries with itself some kind of issues/bugs etc.?
No – it works, but you need to be careful when/if you modify its dimensions (getting it to fit another mesh by changing arm/leg length etc) the problem may come if you rotate bones.
Good to know. And yes, when I appended the armature just looking the mesh and the bones it was quite easy to guess that I will need to adjust sertain areas and redo others completely. Saved me some time though.
