Thanks for trying to help Calinou, I tried the gITF format and everything imports just fine, but with the same issue: It only imports every 7 frames worth of baked animation (I thought it was every other frame, but there's more missing than that). The animation doesn't look terrible, but there are some wiggling animations that update every frame. So where the wiggling happens 11 times in blender, it only happens roughly 3 times in Godot.
Is there an import setting for Godot's animations to take in the entirety of the baked animations?
