HI Materials and transparency need lighting so
They way I would tackle this would be to use 2 different geometries and states One for the front poly with no lighting One for the back poly ( a copy of the front but reversed) with lighting and material Best Regards Gordon __________________________________________________________ Gordon Tomlinson Email : gordon.tomlinson @ overwatch.com YIM/AIM: Gordon3dBrit MSN IM : Gordon3dBrit @ 3dSceneGraph.com __________________________________________________________ "Self defence is not a function of learning tricks but is a function of how quickly and intensely one can arouse one's instinct for survival" - Master Tambo Tetsura -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Morné Pistorius Sent: Monday, July 16, 2007 6:49 AM To: osg users Subject: [osg-users] Can GL_LIGHTING be disabled for only one face? Or someother GL wizardry. Hi all, I have a textured quad that I want lighting disabled on the front face, so that it appears bright no matter from what angle I look at it. But I want to render it semi-transparent when viewed from the back. Is this possible? I tried playing around with materials and a two sided lightmodel, but couldn't get the exact effect I was looking for. Using a material, I can set different alpha values for the front and back face, but that only works if I have lighting enabled, and then the front face is bright only when I look at it straight on. Perhaps I am going about this in the wrong way. Any suggestions? Thanks!
