I''m using D3DTLVERTEX, and couldn''t figure out the best way to bitblt a semi-transparent bitmap that has color keying onto a background image? Would alpha blending be the only way to go? If alpha blending would need to be used, then would alpha blending work on systems that don''t have 3D cards and use RGB software emulation? I tried the vertex colors but changing them only makes the image darker. Is there a way to make the bitmap lighter than the bitmap''s original colors? I want to add a "dimming" effect that allows the sprite to sort of fade out and disappear after certain intervals. Thanks!
