AFAIK only transmit affects the alpha channel. Also, the transmittance value is
automatically stored in the alpha channel and any objects behind the
transmitting object do not affect the channel.
Using an interior (of any kind, I believe) also has adverse effects, i.e. the
alpha channel will always be solid white, regardless of the transmit value.
I believe much of this should be quite easy to fix.
