I updated my mesh in blender so to export it back to the unreal engine 5 . earlier i was having errors related to bones while importing it back in the unreal engine , but after the use of some plugin i imported it to unreal engine without errors. When i tried to change the metahuman body mesh with the updated body mesh imported from the blender , then my whole mesh vanishes as i put the new body mesh in the skeletal mesh asset . Any idea on how to fix this problem?
