View Full Version : alpha in the frame buffer

Hi there,

I would like to clarify something: Changing the alpha of an image stored in the frame buffer (only the alpha), will it have a visual impact on screen? Will I be able to see it less or more transluscent?

If I wanted to achieve that, that is apply an alpha texture to an already textured object to change the alphas of the texture mapped to the object, how would I go about doing that?

NO. the alpha channel stored in the color buffer is only used for blending computation.
