Summary
We’ve exported a Maya sphere as USD with simple skin binding and visibility animation information on it. While visibility animation works in other DCCs, Unreal ignores it when skin binding is present. However, removing the skin binding and re-exporting restores the expected behavior.
Attached are two USD examples for frame range 1001-1024, where visibility turns OFF on frame range 1006-1008. Unreal correctly loads the animation only for the USD without skin binding.
Is this a bug, or is there a setting to fix it?
