I am hoping to learn more about programming by using PD, but it would also be nice to crank out some good looking shaders in a timely manner

HI Cyrille and others. I modified the abstraction to make opening the two files easier. It uses file/parentfolder from the PdMtlAbstractions. (try it !! It answers your question) For the C programming and such, I just meant that it is nice if we can tend to make Pd easier to use for people that are not that much used to advanced programming. A good documentation and a nice structure helps a lot... a 2007/6/23, cyrille henry <[EMAIL PROTECTED]>: > > > Alexandre Quessy a écrit : > > Eh Jack ! > > Very nice examples, yes.
