Again and again the placeholder is adjusted, because sometimes you only notice late if the model meets all requirements. For Ralin the model has to be able to do many things and so a simple model with a small rig became a model with all animation possibilities.
The problem is simply that no asset store or Mixamo animation fits. Everything looks funny and pulls you out of the game feeling.
So the placeholder has already been redesigned 5 times and adapted again and again. Later I can improve the model with sculpting and co. and keep the poly-number under control with retopo.
