I’m not even sure if my terms are wrong here but…
Currently, it feels like additive blending always uses rest pose as a reference pose when trying to make any kind of additive blending. Because of this, it’s really difficult to use additive blending effectively and easily.
Imagine this situation: you have made most beautiful hand shaking animation ever in the world. But then you realize that you need to offset your character hand a bit on Z axis.
In ideal situation you would just make new NLA strip&action and set additive “reference pose” to what is the starting pose of the hand shake animation, offset your hand on Z axis and it’s done.
In current blender situation you have to make new NLA strip&action and set it to additive, but because the reference pose is rest pose, you have to reset all pose transforms on your new action and then offset your hand on Z axis.
Current way is doable but then (As far as I know at least) you can’t see the final combined animation when you edit your new action. So by hitting tab you edit it ,when you are done editing hit tab to exit action edit mode and check results, if the position of your characters hand is not correct, rinse and repeat until it looks correct.
Is there any little button anywhere to make additive blending use the current NLA strips combined transform as reference pose to do the additive blending or is such a thing possible in blender?
