You just add more geometry to the model, duder. If you have everything on one texture sheet, you need geometry to make up for the lack of tiling capability. That way you map each face to the brick area instead of tiling the texture in the mat editor/uvs.
I know I am going to embarass myself by my sheer noobishness but I have recently started creating an environment and I am unsure how I should tile the texture on the building. I am aware of one technique where you can have individual textures and scale up the brick texture via uv's But I have looked at Stephan Morrel's…
