ah, ok I do remember that thread. And you're saying this is the symptom associated that setting?
If so, then the situation is a driver incorrectly reporting invalid value on a valid but unused value. I guess it's not too offensive to compensate by tweaking the unused value to avoid the complaint. Gordon, if that is the issue, could you try changing the ctor initialization value of _geometryVerticesOut from 0 to 1 (src/osg/Program.cpp @ line 99). See how that works, and send to osg-submissions as appropriate. cheers -- mew > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:osg-users- > [EMAIL PROTECTED] On Behalf Of Art Tevs > Sent: Monday, March 24, 2008 5:03 PM > To: OpenSceneGraph Users > Subject: Re: [osg-users] Warning on Add shader to the scene > > Hi Gordon, Mike, > > as I have posted already before (however my patch was > not accepted ;-( , this warning comes from the > geometry shader implementation.
