Been on vacation for a few days now I'm back and feeling all refreshed! Anyway here's a tiled brick texture I came up with for a project I'm working on. Its not spectacular but not too terribly bad either. Mostly just a pattern in the shade of the brick. It looks like when they constructed the building, the brick mason didn't mix bricks from different pallets, so you see a slight variation in color. I guess that's ok as its something that happens in real life for sure. I think a dirt or grunge map would probably help hide the pattern. So anyway I just did this the old fashioned way by copying one side and flipping it over to the other. The first few tries had some really wild patterns in them but I finally eliminated most of them by moving a few bricks around.
Mr_Drayton - I see what you are saying. Makes perfect sense. I went through and tried to clone out anything that caught my eye.
teaandcigarettes - I actually thought about taking that route but didn't in the end. I would really like to give it a try sometime. Thanks for the link to the tutorial by Chris Albeluhn. That's a really nice tutorial.
praetus - Guides definitely helped a ton along with Skew in photoshop. Even the best photo I found to work off of, was not quite level.
TheLastDesperado - I've used the offset filter a few times for concrete, wood, asphalt, anything without a pattern. Its definitely a pain to use with patterns though but you made a very nice point about using it to find bad seams.
Anyway here's the tiled brick I came up with. Its tiled 9 times across the geo to get an idea of how well it works.
