Aim constraints & IK... or something like that
I want to set up something similar to an aim constraint, but this isn't a "aim the eyes at the target" kind of thing.
I'm working on a UT2K4 model and want the arm holding the weapon to establish something similar to an aim constraint so that, as the model wiggles around due to it's running cycle, the arm maintains some sort of aiming vector where it's constantly pointing at something in the distance.
The arm has simple IK connecting the forearm twist joint and the shoulder. The wrist and fingers are raw joints. I've successfully used point constraints to anchor the pole vector locator to a point in the distance, keeping the elbow from wiggling around, but I want to do the same sort of thing with the other end so the gun hand doesn't wiggle, either.
All the help (Maya & otherwise) I've found so far deals with aiming standolone objects (like eyes) at something, but nothing quite like this.
Any suggestions?
Thanks.
