Tutorials to create PRMan similar Shader in MR XSi

[bhamill]

can anyone tell me tutorials or a good book, wich discribe to make shader, like in prman, eg wood without wood pics or rost metal without rost metal pics and so on. i've read, in prman you can make shader without any pics. with textures you have the tiler prob and it looks not very good, then the textures repeat very often, especially on large areas.

Well first of all you don't need PRman to do what your talking about. From what i see you are trying to learn about procedural textures - which can be done alot easier now through the render tree in XSI. I don't know of too many tutorials that go in depth into this topic but i believe that there is a tutorial on how to make a procedural wicker basket texture at www.edharriss.com.
have fun
