I want to be able to load a texture onto an object but when it appears on the screen it doesnt show a certain color that i gace chosen. srry if this is worded wierd. Like how would i go about setting a Color key for a certain color so opengl doesnt show it or loads it with the texture.
I would love for someone to help much thx.

The usual technique is, when you load your texture, loop through every pixel and if it matches your 'transparent' colour, then replace it with [0,0,0,0], then render the image with alpha transparency.
