I had lots of fun writing this, and wanted to share it! I've already gotten a couple friends hooked on this game, hopefully this will get some strangers hooked too.
So I'll try to detail the issues as much as possible:
I'm trying to import an animation with blendshapes into UE 5.6.1
I'm running into an odd problem however; When I had to animation to the rig, it deforms the lower beak in this strange way.
In Maya the animation and blend shapes work perfectly fine. In UE the rig is imported just fine, and the blendshapes move just like in Maya, the values are all normal.
But when I import the animation that uses the blendshapes, it pulls these verts awkwardly up. There's no blend shapes that were accidentally left on, the values are normal, and these verts remove like this steadily throughout. I also tried not exporting the blendshapes, that still didn't resolve the problem (so i dont think blendshapres are the issue)
Because the animation is fine in Maya, and the rig is fine in Unreal, the only place for something to go wrong is in exporting and importing of animation, so I'll explain my process below:
Bake joint keys like normal with any animation
Go into node editor, select the blend shapes, bake them.
Export
Import into unreal, add skeleton, morph targets checked
Check the animation, glitching verts. These verts are completely static too, its like the lower beak is deformed when the anim is added
