Create a duplicate of the slide animation but move the joint to the same position to the position when it's empty.
I did that with all the other animations but they had a spot in APE to put the empty animations. The slide animations only has these options:
Slide In Air
The sprint animations has these options:
Sprint In Empty
Sprint Loop Empty
Sprint Out Empty
I could make the slide empty animations, but how would I apply them to the gun and still have the normal slide animations?
