Importing really simple models with a low bone count with no issue. The hand has been glitching all day. Still no closer to solver the problem. Unfortunately I’m working with Visual Express C# and my old Visual Studio Pro 2005. Which makes debugging the pipeline a bit of a bitch, as Visual Express does not have a JIT Debugger.
Not sure what part of the hand is given trouble, to be clear other simplier skinned test models work fine.
