I was mistaken. There is apparently no dot 3 blend mode for entityblend in Blitz, only for textureblend. I do not think there is any reason for this limitation... I think Mark simply chose not to support it for whatever reason. Regardless, without a Dot 3 entityblend mode there is no way to do the effect I described above.
I'll see if I can think of any oher way to accomplish this effect, but don't hold your breath!
