View Full Version : Texture with Alpha embeded?

06-12-2004, 11:20 AM

Is there a way I can use a texture with it's alpha channel to do texture blending?

I want to use a texture on top of another one, but so far I can only do it as long as the alpha channel is a separate texture.
For example, I have a base texture (layer 1), then I have to put the seconde texture I want to blend with with the base texture (layer 2), then I have to add an additional (3rd one) texture that is a B/W texture for the alpha (layer 3) so that the second texture (in layer 2) be selectively applied on top of the base texture like a "decal".

Now, I would like to use the alpha channel in the second texture (layer 2) to do the "decal" effect, without the need of a 3rd texture (alpha texture = layer 3)

Please, let me know if you need more information.

You should be able to 'Enable' the alpha in the Image editor, then it will be applied automatically.

You are the best!

Thanks a lot, that worked!

Alpha channels doesn't seem to work with BMPs.
