Thanks for the reminder - I had a no_shadow method you might be
interested in too:

"by adding steps to my shadow scene so the shadow raises"...?
You mean so that you get self-shadowing of the legs?
Can you just add some sort of shell of the legs (scale 1.0001) over the actual
legs and use a y gradient between rgb shadowVal and rgbt1 to fake the
Or maybe just shift the actual leg geometry a bit toward the camera and use the
same pigment gradient as a shadow overlay.
Or something like that..
