I've got my 2d opengl game up and running but I'd like to clean up the interface and make it look... Well... Cool. I'm trying to work out the best way to put a glow effect around some of the text(which are just opengl textures). Are there any tutorials? I know some games have this effect so I know it's possible... I'm wondering whether they just added more textures in behind though and messed with opacity... Which is a bit of a pain to be honest.
