Texture mapping with nodes on walls So I'm using nodes to make my brick texture tile, but it always get stretched on one side of the wall.   It's just one plane subdivided and extended faces. How do I make it look same on all walls?
You have to unwrap your wall: In the 3D view, in Edit mode, select your whole mesh and press U, and choose for example Smart UV Project or Cube Projection option, then in the Node Editor plug the UV output of your Texture Coordinate node into your Image Texture node, then in UV/Image Editor, rotate or scale the parts of mesh you want so that the bricks appear correctly in your 3D view.
