I've been trying to figure things out with these motion capture animations today. Basicly, the good thing is that getting the motion capture to work with the mesh isn't really a problem anymore, and I also manage to get the animation loops to go pretty smoothly too. The problem is that my character has (i think) different origin points in different modes. Shortly put: when I import the animation to Unity, Eve walks few feet above the floor.
So i guess the next thing is to figure out what's causing that and then continue working w/ animations..
e: i think i know what the problem might be. I think i'll have to go to pose mode -> pose -> clear transform -> location (rig snaps to same place than when in object mode etc), then i need to insert location keyframe for all the frames.. but i don't know yet how to do it..
