Adjacent polygons don't know anything about one another inside the GPU pipeline, so they can't scheme together to line-up their brick edges. One way I've solved this in the past was to create a 3D texture containing a brick pattern (each brick was a contiguous span of pixels/voxels of the same colour) and sample that using the worldspace position of the shaded pixel. It requires some mathematical artistry to turn the in-between gradients into convincing looking grout lines though. | |
