Hi,
I made this wall whilst playing with bump mapping. I'm quite pleased with it, but I'd like to give the bricks a bit more depth. I've tried increasing the bump map depth but I have reached the limit before it begins to look bad. Any other ways of making the bricks extrude in more detail?

How do they do it in games like the screenshot here:
