Hi all, I've done quite a bit of trawling but cant find the information I need - its probably elementary and I just cant see the wood for the trees.
I want to layer images over each other, with each layer using the alpha channel to control the transparency as an image sits over the previous layer(s).
Is it the blending flag, in which case would anyone be so kind to provide a working example? Do I have to scale the RGB values by the alpha channel? I'm a bit lost - help!
