I just did an A/B test of your 3rd version with Tor's reworked version, and the
first thing I noticed in Tor's was some coincident-surface speckling of the HF
base--NOT related to the plane (I moved that out of the way.) Perhaps there are
some duplicate slices at the base? (Just a guess.)

Also, with your version, water_level can be used in the HF to erase the base (or
any part of the HF.)  In Tor's version, water_level doesn't behave normally, and
instead produces some odd results (a square block shows up below the
water_level.)  Just thought I'd mention these differences.

Keep those developments coming!!
