So i’ve been trying to get some meshes inside UE4 and i get a weird issue that i think is related to the Up axis orientation.
I’m exporting from max 2015 using FBX 2013 with the Y up option, but my meshes receive correct lighting only when rotated 90 degress on the Y axis in UE.
You can see the mesh without any material applied receive correct lighting. If i apply the material it gets shaded correctly only if i rotate it 90 degrees on the Y axis.
I’ve also checked for a flipped green channel on the normal map and it kind of weireded me out that nothing changed between the 2 : /
