Reply To: Randomization in Animation

[shadston]

I am using bones rotations and positions in the animation clip. I guess I am after specifics for example how to connect custom mixer to animation graph. I know how to do it in a simple script but I don’t see an option to integrate it with your API. Putting separate track above random blinking track causes my character to blink with closed eyes (no matter how weird it sounds). This is my blinking clip. The best scenario for me is to cover whole track with a random blinking and put specific blinks in between, but then I can’t guarantee that I won’t start specific blink with eyes closed, so I need a way to blend it nicely no matter in what state are eyes because of the random blinking. I thought about tweaking whole track weight, but maby you know a better solution.
