Currently, leylines render on blocks by positioning the leyline quads a short distance above the normal block quads. This is because the leyline layer uses 4 quads per side to facilitate connected-textures, but it means that the leyline textures won't be applied on top of the normal block texture as a decal.
The current way to rendering leylines mostly works, but if viewing the leylines from a distance, some z-fighting is visible.
The best way to fix this would most likely be to divide the face of the block beneath the leyline quads into 4 quads per side, just like the leyline quads, so that the leyline quads apply as decals.
