This is a quick tutorial showing how to much the console transparent for a nifty look.

Open up the file gl_rmain.c and find the function R_SetGL2D. You should see:

 
 
void R_SetGL2D (void)
{
 // set 2D virtual screen size
 qglViewport (0,0, vid.width, vid.height);
 qglMatrixMode(GL_PROJECTION);
  qglLoadIdentity ();
 qglOrtho (0, vid.width, vid.height, 0, -99999, 99999);
 qglMatrixMode(GL_MODELVIEW);
  qglLoadIdentity ();
 qglDisable (GL_DEPTH_TEST);
 qglDisable (GL_CULL_FACE);
 qglDisable (GL_BLEND);
 qglEnable (GL_ALPHA_TEST);
 qglColor4f (1,1,1,1);
}
< font>

Change the last 3 lines from

 
 
 qglDisable (GL_BLEND);
 qglEnable (GL_ALPHA_TEST);
 qglColor4f (1,1,1,1);
 
 

to

 
 
 qglEnable (GL_BLEND);
 // qglEnable (GL_ALPHA_TEST);
 qglColor4f (1,1,1,0.3);
 
 

Thats it! the parameter 0.3 can be changed to suit your taste but it should look good as it is. I'm not sure how this change actually works since I was mucking around late one night and not sure what I was doing :)
