Geometry creates visible seam on part of model

Support Materials and Textures

I have the issue that there is a visible seam on part of my model while other parts that look exactly the same do not have such seams. Can someone explain to me what the issue is?
You can see the seam exactly in the middle of the roof here:

While there is not any seam on the other side, even though its exactly the same geometry:

Thats what the geometry looks like:

Some things I tried: Checked for normal orientation: Everything is facing the right way. Applied all transforms. I also checked if moving the UV Islands makes a difference. Oh and all UV Islands (from the roof) are sharing the same UV Space.
Anyone got an idea?

Can you upload the file + texture here?

I believe the textures should come with the blend file right?

not unless you check the pack ressources box :slight_smile:

but just give me the image separately

but I think it’s just because the sides of the roof are not completely flat. If you open up the context menu and select shade smooth by angle, the edge should disappear.

For some reason this website wouldnt allow me to upload the normal maps, so heres the textures uploaded on a separate site:

Thank you, auto smooth helped. Shouldve thought of that myself.

Also you might want to switch the color space of the normal map image to non-color instead of sRGB. Those are often the source of strange artifacts in my experience :slight_smile:
