Hard line on surface

Hello :slight_smile:

I’m struggling to apply a texture on the floor of a scene where I can see a hard line. No clue why.

I was trying multiple textures from different sources and noticed a hard line an then i went back to very simple texture with Principal BSDF and still have the same issue.

All normals blue from camera.

So I guess the issue isn’t the texture but the model ? Can you help to find out where this is coming from ?

Bonus question ; for such corridor, will you keep walls, floor, ceilling within the same mesh or will you splir them into multiples meshes ?

Thank you :slight_smile:

Here is the complete scene :

And the file :

you did not include any textures
so hard to see that hard line on floor !

probably some ceiling or wall line being reflected on floor !

happy bl
