Hi, The bricks shader that is available in the file i've put on e-groups is not procedural . But there is a procedural cracked tile shader in the pack . And for those who wonder how bricks could be done using a procedural function, go see the extension pack Eric Winemiller have done . It is freely available on http://digitalcarversguild.com . Anyway, it's good to see people use the shaders i've done ! litst
