It is more 'repeating' shaders. It depends on how you got those bricks on it in the first place. If they are from a texture, you need to 'tile' them. The word you will find next to the 'texture map' part of the shader. You can only have 30 tiles maximum, but when you buy ShaderOps from Digital Carvers Guild, that limit is gone. And you get a lot of other cool options extra too. If you made them in another way, there may be other sliders to hassle with. But, eh, a submarine with bricks? I am sure it will be easy to put under water, but returning to the surface sounds like a problem... ;-)
