Static Mesh Shading Artifact

[IdrisKhan]

I trying to import a static mesh of a building floor that I have exported from Maya 2024. However, one of the sides of the static mesh seems to have some kind of a shading artifact. This artifact is only visible when i drag the static mesh into the level, even though, In the unreal static mesh viewer, it seems to look fine, as it did in Maya.

Here’s a screenshot of the static mesh.

Here’s the FBX

I’m clueless about why its happening. All the other meshes that I have imported so far seem to work perfectly.

What am i doing wrong here, and how can i fix it? PLEASE HELP!!

Normal problems

It’s also easier to get it right if you make it modular. Just wall sections, and windows etc.

Hi! I can’t open your file yet. But I think I know whats the probleme. You don’t have shading groups on your mesh. If you have Blender I can say the steps to fix this. Blender–>file–>import–>import fbx. Select your mesh–> hit tab–> hit Alt+A ->hit 2(not on the numerical)–>Select–>Select sharp edges–>Edge–>Mark sharp–>Hit tab again–>Object–>Shade autosmooth–>On the right side of the screen select the blue wrench–>Add modfier–>Weighted normal–>File–>Export–>Export fbx–>Check Selected only–>Under geometry–>Smoothing–>Edge–>Then click on export FBX. This will solve the shading issues, but the binormal will the same, bacause it’s caused by the wrong UV.
