If you've ever created 3D scenes, the likelihood is you've needed a brick wall at some point. I have found that finding the right RGB texture to be time consuming, trying to scale it without repetition difficult and they used too much memory so I was limited in the complexity of my scenes. Even if you haven't yet and you're just starting out, you'll probably need one at some point!
The Infinite Wall Builder is a procedurally generated brick wall builder which uses a huge amount of controls and effects to pretty much create any wall you want and as many different walls as you need, safe in the knowledge that the IWB will fill your mesh seamlessly. You'll never need another brick RGB texture again.
