Custom Touch Hand Animations

Hi all,

We've setup some custom hands for our game, I've got the grabbing via Flex working not a problem.
The issue we're having is with the Thumb & Point layers overriding, the animations are also overriding the other fingers/thumb which kills the grab animation.

Can someone shed some light on how this is done correctly? I'm not technical with animation and trying to explain it to my animator isn't working. :)

Thanks,
Dean
