Can you be a little more precise as of what your problem is, Alexey?
You don't want the alpha channel to be anti-aliased? If so, one
solution is to make two renderings, one normal with -ua and +a and the
other with +ua and -a, then use the alpha channel of the second with
the image channels of the first. Or you can give your object a
completely white pigment and an ambient of 1 and render it against a
black background with anti-aliasing switched off (which is basically
the same as the previous method :) )

(BTW if explanations in Russian will be easier for you, you can
contact me at my TAG address below)
