Transparency within Subtool, Not Just Between?

I can activate subtool transparency and render a subtool transparent so that I can see other subtools and document backgrounds through the subtool, but I can’t see other parts of that same subtool through the subtool.

See the image below – the red (choroid plexus) shows up fine within the blue cerebral ventricles, but I can’t see the farther back edges of the ventricles through the closer surfaces of the ventricles.

What gives? I can’t imagine zbrush can’t render this kind of transparency - I must be missing something.

Haven’t found an answer to this yet through searches or a couple books.
thanks for the help!
