I just started using the free addn Spring bones https://github.com/artellblender/springbones
It work like a charm,easy to use, make jiggles and even collisions. In viewport the animation works just perfectly,it even loops 100% perfect,however , it is impossible to render this perfection,it barely even work once the animation is rendered.
You are supposed to NLA Bake but it just does not work in final rendered animation.
Anyone knows how to keep these transformations in viewport in a final render? (the addon make selected bones jiggle,i try to find a way to keyframes those,but all Baking i try do not do that)
