Initially I was worried that upgrading would break everything, but it went very smoothly...i'm using GL_COMBINE_EXT now and it works a treat. Thanks. -----Original Message----- Sent: 10 March 2005 10:51 To: Multiple recipients of list OPENGL-GAMEDEV-L it is looks like u r using OpenGL 1.1. Why don't u use newer versions?. You can simply define a CG shader or fragment program to indicate how to combine texels RGBA with fragment color. In that case, u can ignore alpha channel. Register combiners operations like COMBINE_EXT even works.
