The Animation mixer can play one or two character animations at the same time on a given animation channel. When playing two, it mixes them based on the blend ramp asked for, via the ANIM command and the Animation Agent Script.
- <blend> can be a value between 0.0 and 1.0. The default is 0.1
If a third animation comes in, it is not ignored. Instead it causes a strange visual problem where the character snaps to "root pose" for a brief moment. This happens because the older of the two animations is discarded and then it is blending the previous new one, with the new new one... but the previous new one wasn't at 100% yet so you get some root mixed in. Anyway, nothing is ignored.
