Need help for custom enemy

[Juras]

First of all, you can use IKs and Controllers for your skeleton, but when you're finished with an animation, you need to bake the animation (it's called "bake simulation" in maya) and then remove all the IKs and controllers so you only have joints left. The animation will still be the same as you made with IKs and controllers since you will basically key every frame on the joints.

The second problem that you're having is happening because once you bind a skeleton to a mesh it will make a bind pose which is what you will see in the model viewer unless you make an animation. Since you're monster will never be static why bother making his arms down if it will have an idle animation where you can put his arms down anyway?
