[Sidefx-houdini-list] where are the default shadow shaders?
Tuesday, 27 October 2009 Tue, 27 Oct '09
i was asked the other day is it possible to have a combination shadow shader that reads a shadow map and retraces some objects, by making a shadow shader that is a bit more complicated? 2009/10/27 Szymon Kapeniak <szymon.kapeniak at gmail.com>
ups, I didn't understand you. If you add VEX Shadow shader in Shops, this is apparently the code used in default light. It's usually saved in OPLibShopVMantra.otl. 2009/10/27 Robert Kelly <isstuff at gmail.com> > yes i am doing that now i just want to know where the original shadow > shader > code are so i can add to them in staid of reinventing the wheel. > > 2009/10/27 Szymon Kapeniak <szymon.kapeniak at gmail.com> > > > The simple way is to add "shop_shadowpath" property to a light and apply > > own > > shader this way.
