Hi Mikay², Because Tessellation caused some error on mesh, also confirmed as a Known Issue on Unreal Engine. https://forum.reallusion.com/410267/Tessellation-issue-in-Unreal-Engine https://answers.unrealengine.com/questions/661180/is-this-a-tessellation-bug.html So we added a Tessellation Mask Map on HQ material and set its Parent Material (RL_HQSkin) as No Tessellation. If you want to add it back, please change No Tessellation to PN Triangles, and you will see the result on character. Hope this answer will help! Calvin Reallusion.
