Normal ( bake ? )

othyz

Hi, I baked my mesh in SP, and when i import it to unity i see some weird shading going and when i check the normal map i see theres a gradiant on flat surfaces. i don't know where i am messing up

gnoop

it's totally expected behavior.  You should edit  the vertex normals the way they would be  perpendicular to a surface you prefer to look flat   "faceweighting"  them  or split edges for same purpose

othyz

they are perpendicular, i don't have a problem in the vertex normals i have a problem in the normal map as you can see the gradient in the image so even if i split the edges that gradient will appear either ways, i don't know how this could be fixed

Gradients on normal maps are perfectly normal behavior like gnoop said. It's from the normal map having to compensate for the shading/normals/smoothing on the low poly model. Are you sure Substance Painter is importing the smoothing on the low poly model?

yeah i had a problem with exporting the smoothing groups correctly to SP, thanks guys!
