![]() It's not a question of “is learning rman any different than learning mantra” - the answer to that is yes, of course it's different! They share many similarities but they have differences in some approaches and certainly syntactically. I think the question is a little misplaced. Answer 2: Learning how to assemble a shader, how to deal with attributes and the general understanding of programming constructs will make you an even stronger houdini user. All shops certainly could use strong shader writers along with good Houdini skills. This industry needs more visual effects artists that can re-assemble ribs and write their own shaders to get around production issues. You ask “why spending time and money (and this is really BIG oney) studing PRMan?” Answer 1: There are so very few people in this industry that can write even simple trivial shaders. How do you write an illuminance loop let alone do one in VOPs? You have to read the Renderman Companion to get the basics then read the Advanced Renderman Guide to fill in the holes then attempt in VOPs. Just looking at a vop network won't get you there for advanced shaders. You can apply what you learn to VOPs though and for the most part completely disregard aliasing issues as each VOP is written to be self-anti-aliasing. Advanced Renderman and the Procedural Texturing and Modelling books do go in detail on how to anti-alias your shaders and that is where the understanding of calculus comes in most. The big issue with writing shaders for RenderMan and Mantra is managing anti-aliasing and the nyquist limit (what?) due to the very nature of how the two renderers evaluate shaders at the micro-polygon level. Second, it is necessary to study how shaders work and how RenderMan and Mantra call shaders in what order and when, if you want to do more than just layer shaders and use simple lighting models like phong, blinn, lambertian with lots and lots of texture maps.
