I want to implement a new BRDF in Cycles.

I've already tried to code an OSL node but I couldn't because the way that BRDF closures are implemented in OSL seem to only permit BRDF closure composition.

I would like to now the standard (simplest) protocole to add a new BRDF closure in Cycles. I've already had my own blender build so I can modify the source code if there isn't another solution.

Edit : Or maybe, somebody eventually know where I can ask to get the answer ?

    $\begingroup$ Welcome to the site :) Note that questions about modifying the source aren't considered on topic here. If you are looking for an OSL answer that's great, but for source code questions you might try asking around on IRC and such where you are more likely to find a developer :) $\endgroup$ – gandalf3 May 11 '15 at 8:49

    $\begingroup$ So I don't know yet if my question is out of the scope ! I'll try on IRC or mailing list. Thanks for your answers :-) $\endgroup$ – Boris RAYMOND May 12 '15 at 9:08
