1. Normal Artifacts in UE5

   

   

   Topic by Sani · Aug 2023 · Home› Unreal Engine

   HI, i'm a 3D artist starting to learn UE. I imported my low-poly mesh into unreal and also imported baked normal map for it (directx format). With normal map applied to the model on some details there is a shift in place of UV seams, other details have obvious distortions, and these artifacts appear only in UE, in other…

   Yea, I triangulated my mesh before export

   Hi! I would try turning on "Use Full Precision UVs" for the mesh in the static mesh editor in Unreal. By default static meshes use half precision UVs to save memory. Edit: Unrelated, if you re-use UV space for mirrored/repeating elements you can increase texel density, meaning less jagged edges. Could use a second UV…

   Hi! Did you triangulate the model before baking, to ensure the topology is consistent across applications? It would be good to have more info (lowpoly shading, UVs, wireframe). Ideally, share files.
