Hi,
New here and fairly new to opengl…
Dunno if I’m being daft but there seems to be little information about how to change a texture once its loaded in.
Just wondered if there was any way to brighten or darken a texture.
glTexEnv seemed to be heading in sort of the right direction, where you can apply effects based on the underlying colour of the polygon but i don’t think that’s what I am after…
Any help really would be greatly appreciated,
Thanks,
Mal.
