Robert, Gordon, This issue looks like it might be the same one I experienced back in February (http://forum.openscenegraph.org/viewtopic.php?t=1656)
I never took it further as my need soon became OBE, but at least it's another potential data point. -- Dan > -----Original Message----- > From: Tomlinson, Gordon [mailto:gtomlin...@overwatch.textron.com] > Sent: Monday, June 01, 2009 11:22 AM > To: OpenSceneGraph Users > Subject: Re: [osg-users] Problems using setResizeNonPowerOfTwoHint(false); > > Hi Robert > > Ok we will give it a go and get back to you > > > Gordon > Product Manager 3d > __________________________________________________________ > Gordon Tomlinson > Email : gtomlinson @ overwatch.textron.com > __________________________________________________________ > > > -----Original Message----- > From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users- > boun...@lists.openscenegraph.org] On Behalf Of Robert Osfield > Sent: Monday, June 01, 2009 12:50 PM > To: OpenSceneGraph Users > Subject: Re: [osg-users] Problems using setResizeNonPowerOfTwoHint(false); > > Hi Gordon, > > I've just tracked down the original posts from Mark and have looked at his > sample and suggested fix.
