Not sure anyone but the 3E/Excalibur team can help with this, but...
I copied the keyframe controllers from FCExcelsior to Righteous model, and all loads ingame ok, but as soon as 'door opens' (which I think is triggered by common animations script), game quits to desktop with 'encountered problem' message. I'm pretty sure copied properly, and in right sequence in node, hence why loads ok.
