Hi,
I have searched the forum and found some posts about doing Chroma Keying with Ogre3d but it is still not clear to me how to do it. Can anyone explain how to set up a material script that lets me specify a certain rgb color value to use as the transparent color in a texture?

Thanks

It's not possible really, unless you use shaders or modify your textures dynamically. You're better off saving your textures in a format containing an alpha channel.

Colour keying went out with palettised textures and other dinosaur techniques Alpha channels are in.

Thank you both for the quick reply. I guess I was stuck in GBA dev mentality
