I have been having many problems blending actions in NLA and need some advice. I am using Blender2.49b. One problem is that a bone with a ChildOf constraint on it works fine when its influence is set to 0 or 1, but acts funny when the influence is somewhere in between. I don’t know why, but the bone with that constraint moves in odd directions when the influence is between 0 and 1.
Another problem is blending between actions where one action uses FK and another action uses IK. Is blending between FK and IK actions something I can realistically expect to be able to do? Or is it inevitable that any attempts will produce strange results? When I do this, the influence of IK constraints is between 0 and 1 so I wonder if it could be a similar problem to the bone with the ChildOf constraint.
I also have actions with characters moving their arms defined with it standing up but I’ve been using the actions with the character sitting down. So far there havn’t been too many problems with this, but there are still things to fix. I was wondering if anyone has any experience in this area and knows if it is worth the time to try to define actions in this way or if I should define separate actions for the same arm motions based on whether the character is standing or sitting.
