Hi people, how are there?
I'm trying to create a tool that transform animation (Pistol shoot animation) to an additive animation, I searched in a lot of places and the only I've found is subtract the source animation with reference animation (frame 0 or 1), I try it to apply that, without get a good result, I don't know if I can achieved this wit KineFx, any help is appreciated, thanks a lot in advance, regards.

You can likely use Pose Difference SOP to compute the delta between 2 poses and apply to 3rd

Thanks a lot for your reply, I've tried what you tell me, but I don't know if I made the correct addition to third pose

Pose difference can also apply the delta directly especially when computed from custom matrix attrib, but I don't recall the order it computes the delta in so It'd be easier if you post simple example scene

Sure, this is an example file, in that file, I've calculated the animation delta with pose difference sop node, and also I've tried to add that delta to rest pose, the code in point wrangle I've copied from a node inside pose difference, thanks a lot in advance, regards

you can try computing and applying the difference in local space
