I create a simple modular wall with uv channel within. I duplicate it several times in order to apply a material with a blend texture which takes de position of the wall and moves accordingly. But ,when i apply some lights in to the scene, the shaders creates ugly lines in the intersection of the walls.
I use Lightmass volume and the walls are well snap. I also make the test with a second UV Channel but nothing happens.
Who do i fix this problem.
