I've got rid of the "invalid enumeration after RenderBin::Draw" error by setting the source format texture->setSourceFormat(GL_LUMINANCE);
The other error I get still remains: "invalid operation after RenderBin::Draw" > ----- Original Message ----- > From: [EMAIL PROTECTED] > To: "OpenSceneGraph Users" <[email protected]> > Subject: [osg-users] Floating point texture problem > Date: Wed, 28 Nov 2007 21:58:20 +0800 > > > Hi, > > I've got a project were I want to render a floating point texture. > Currently im using a texture rectangle with GL_RGB as a render > target which is attached to a prerender camera.
