Hi Mike, Thanks for the info! It's at least good to know there's not some better way I should be going about it :)
Does anyone know why my uniform might not be getting the right value from the OSG framework? Is this something that was likely fixed in a later version (I'm using 1.2)? -Nathan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Weiblen Sent: Tuesday, April 01, 2008 11:02 AM To: OpenSceneGraph Users Subject: Re: [osg-users] Uniforms and state sorting Hi Nathan, > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:osg-users- > [EMAIL PROTECTED] On Behalf Of Monteleone, Nathan > Sent: Tuesday, April 01, 2008 10:04 AM > To: OpenSceneGraph Users > Subject: Re: [osg-users] Uniforms and state sorting ... > I'd think the uniform state would be independent of the GL_TEXTURE_2D > mode.
