the blending won't happen unless you add a line to enable the blending: glEnable (GL_BLEND); //enable blending mode glColor4f(1.0f, 1.0f, 1.0f, 0.6); // Full Brightness. 50% Alpha glBlendFunc(GL_SRC_ALPHA,GL_ONE); // Set The Blending Function For Translucency

OK thanks for that. As soon as we get FTP access back I plan to go through and fix some of these little bugs in the old tutorials. Thanks for your help.
