Messed normals

[lunar flax]

Looking even dumber with envmap on

The face is flat, even if there are tiny faces, it SHOUDN'T fuck the normals up this way, what's happening

There are no duplicate vertices, the model is absolutely perfect in Blender.

Even after cleaning the mesh, those edges are FUCKING with the normals it's actually crazy.
Like, just do it FLAT, what's going on ???

disabling auto smooth, I can see the issue. But why is it that why

Fixed it by fixing the normals without auto smoothing, by separating from sharp edges

way to fix it
in blender when u add an auto smooth shader the object add automaticly a modifier

then u can edit the angles to set better sharp

other way u can add in edit mode a mark sharp in Ctrl + E menu

with that u can control manually what is sharped or not
