Brad, Looks like I need to upgrade from OSG 1.1 to 1.2 to be able to do this. But, if it gives me the ability to attach textures to the light points then it sounds worth it.

This will enable point sprites. You will have to attach a texture to the LightPointNode as well. Look at any of the point sprite examples. -B --- RSC BDC > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:osg-users- > [EMAIL PROTECTED] On Behalf Of Zach Deedler > Sent: Monday, November 13, 2006 12:55 PM > To: 'osg users' > Subject: RE: [osg-users] Light points render slooooooooow > > Farshid, > > Thanks a lot.
