Hm, how can you say that the rigging is great when you never have animated with it? It`s the animation that shows if the rigging is really good

Anyways. The Blender bones system is not really bad. It is somehow up to date and solid. And it is a good and working bones system. So you cannot really go wrong with it. But it has its flaws. It is a bit complicated to rig here and there. What really disturbed me was the IK setup. I don`t really like to create a second skeleton to control the first skeleton. And the need to use floating bones for IK reasons is also something i dislike.

From what i`ve seen so far is that the Messiah Bones System is definitely easier to handle, while it opens up even more posibilities. And better is the enemy of good
