You'll want to go into the curve editor (Graph Editors > TrackView - Curve Editor) select those keys and click on the "Set Tangents to Linear". Which is the Euler way of handling curves, Biped by default uses Quaternion and the TCB values (Tension Continuity and Bias) to control curves. Biped can be set to use the Euler…
I'm currently animating a tarantula for one of my classes. I built a custom rig for it and animation has been going pretty well so far. The image below shows the rig, and how the dummys are linked up. I have one dummy for the main body, as well as one for each appendage. The IKs for the appendages are linked to their own…
It doesn't stay in place if I copy the keys, as can be seen below. In fact it makes the problem worse. The limb dummy follows the main dummy almost as tho there are no keys at all, and then snaps back to the original position at the last key. Perhaps I should explain how I've gone about animating up until this point as I'm…
