Thank you for sharing more of these ideas of
yours yooper !
I have not yet made any "cylinder antiblobs",
but maybe it will produce exiting results.
(The math wouldn't bee too difficult I think
...)
And yes: IIRC one can use cylinder
components within blobs.
But unfortunately at the moment I don't have
much time for POV-experimenting either.
=(
BTW: Are you working during the night ??
