Using 4.21. I created Skeletal Mesh LODs using simplygon for Maya. Everything in Maya shows up and works well, all LODs and morph targets. However when I import my fbx into UE4, only the LOD0 morph target shows up. I have tried deleting the usset, reimoporting, nothing seems to work. I see all the LODs but only the LOD0 morph target. Any ideas? Thank you.
