I have a … fishy problem I can’t seem to figure out. The underside of my model is always “flat”. Though I can see the normals from an angle, the further towards a view straight from below, the normals “flatten” from view making the object appear as if it has no normal map on it. If I rotate the mesh in the 3D program and reexport it, the issue then appears on what is now the bottom. I can see this happen on the default shapes I view my material on as well, but I can’t seem to figure out why.
Even if I make a brand new material and use any of my normal maps I get this behavior. I’ve tried flipping the G channel, made sure sRGB is off, and everything else I can seem to find. It’s probably something I’ve done. Which ever side of the model is down, even if it’s at an angle, is flat.
