[TuxKart-devel] Alpha not working nicely on RaceGUI.cxx

[<ri...@ae...>]

Hi there,=20
=20
 Just wanna report that alpha isn't working that well in the=20
RaceGUI.cxx code. =20
I suspect it is because of this:=20
=20
  glEnable       ( GL_ALPHA_TEST ) ;=20
  glAlphaFunc    ( GL_GREATER, 0.1 ) ;=20
  glEnable       ( GL_BLEND      ) ;=20
=20
 I don't know OpenGL that well, but shouldn't this be something like=20
this:=20
=20
glEnable(GL_BLEND);=20
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);=20
=20
Cheers,=20

Have you tried it?

(Sorry, I don't know either.)

 Yes, I have. Doesn't work either. :P
 Maybe it is just that blending is disabled somewhere... I'll have a look at 
this.

Cheers,
