Ploblem tiling a displacement map So i created this displacement map based on a mesh of windows i made. The map works fine but when i try to tile it there is those separating lines on the z axis. It does that whether i use the displacement modifier of the displacement slot of a shader.
Well, in the EXR image opened in Blender you can clearly see the lines in the top and bottom of the image, as well as in the viewport:



Just paint them away with Gimp, for example (which supports float EXR textures nowadays)
