Hi.  In Carrara pro 5 is it possible to make the brick textures tile smaller, because some of my models that require them look really silly with huge giant size bricks?

Since I am coming from bryce, I was wondering if it is possible to do the following:

Create an infinate plane and texture it with clouds.  I know I can create a infinate plane in carrara, but how do I texture it with a cloud material.  I looked in the shader room and could not find cloud textures anywhere, yet when I insert a cloud, it is textured.  What am I doing wrong?

Thanks.
