Hello again. Thank you for your response. I don’t really see much difference where your working animation and mine diverge. I also dont see a Blender file, unless its just the screenshots. I did do a few more tests and came up with some interesting results and theories. I tried exporting my animation as a .glb and it imported A LOT FASTER, but the legs did not move, but the creature was able to turn and bend its body. I also got an interesting Output Log for it as well as import messages. Ill provide a screen capture below.
I eventually thought that maybe its my action or NLA editor. I am using NLA strips that I would bake into one strip and export that, but maybe I am doing it wrong and you might notice something? I also later noticed that objects that were not supposed to be a part of the end animation also got their NLA’s stored in the armature. I tried deleting all but the few strips you will see in the screenshot Ill provide. Thank you again!
