I have a model with several morph targets, and a few of them are causing weird shadows along the deformations. I tested a standalone version of the morph target (i.e. as a static mesh) and the issue is not present. In the attached screenshot you can see how the front model has the issue (this is the SkinnedMesh morph target version) with the World Normals and the back model looks as expected.
Am I missing some import or export setting for my FBX file? I’m exporting from Maya 2023 as a 2020.3 FBX with default settings and importing into UE 5.0.1 with default settings except for “Import morph targets” enabled.
