Hey, until someone chimes in with a solution as I can’t think of anything else to try, while you’re developing the game whitebox it to get the mechanics all working so for now I’d just use proxy with “dummy” animations (or “Programmer Art” as I use that all the time prior to final art assets and animations), unless you need an animation fully to test it but definitely don’t redo anything. Especially since it worked in the older versions. I’m sure a solution will present itself to this weird issue.
