Hi all,
Maybe a lot of you guys use this website already. (Dutch link. I think it's available in other languages too)
http://www.wienerberger.nl/gevel/productzoeksysteem/terca-gevelbakstenenI bump into it a week ago and used it a lot since.
The site generates brick textures for free. Less quality then a lot of brick generator out there but for me (as an architect) the main advantage is that the are based on real bricks.
The textures are not useful for close up but for distant buidlings with nice seamless textures it works for me very well.
btw select a brick. Then go to textures. There they have hidden the generator.
