weapon aiming

I got my aiming animation stuff working, sort of. The editor now allows one animation to be added on top of another. This allows me to blend a shooting animation with an aim animation, like this crude example shows:



However it doesn't always give good results. My test animation looks alright when aiming upwards and straight ahead, but not so well when aiming downwards:



As you can see, the support hand doesn't stay where it's supposed to. This could be solved by changing the shooting animation or by using IK for the support hand. In the game, the aim animation would be controlled by the crosshair position.
