Sure looks like a bug. But it would be nice to have it as a feature - diffuse
tranmittance is very
useful when rendering thin paper, matte plastic lamp shades etc.
This "bug" seems to work exactly like diffuse transmittance - if only we could turn it
on/off for all
objects.
I've used dense media to achieve the same effect, but it's very slow.
