UE4 FBX Mesh help

oxblood

Hi guys, i'm working on my first UE4 scene and I cant figure out why my meshes come out so strange when I import them. The uvs and lightmaps are kl because they work in other programs but when i import them into Unreal it looks like this. Anyone got any ideas ? would really appreciate the help

Haven't had enough experience with the engine to know for sure but it looks like it could be an issue with the smoothing groups?

I just double checked. Its not that

If you're using normal maps make sure they're baked with -Y direction. If not invert the green channel basically. Also make sure you're importing the texture as a normal map (double click it and make sure it's a normal map).

Besides that maybe try exporting and importing your fbx with the normals and tangent space?

I was getting some issues when exporting with Crosswalk 2014 (FBXSDK 7.4), using 7.3 instead fixed it.

You may upload your model here, I will test it with my UE4. If you work with max, upload .max file, or in .fbx

Need to set your FBX format to 2013 instead of 2014
