I made my garment using marvelous designer, converted it to quads (optimised) before exporting as obj to blender, then from blender, merge vertices, add thickness using solidify, etc, before exporting as FBX to UE.

Was wondering was is causing it and if anyone had similar experience and solved it, please share.

Thank you.

Could it be Z-fighting? Perhaps you have multiple meshes superposed on one another; potentially coexisting LODs.

Don’t think that is the case. I’m still at testing phase, so there’s no LODs on the garment.

What about deactivating recompute normals?
