So I have been very annoyed at the fact that we need to upload animtion in order to play them. And worse there is no way to delete them.
It also clearly possible to play animations without uploading due to the fact there is a animatior in the editor.
With this i have made a custom animation player which plays the keyframe sequences from the produced from the animator
currently it is very crude, no way of stopping, no speed adjustments and playing multiple animations at once but I hope to refine it so it can be as good as playing the animation on the humanoid.
