The way I do this is to change the color of the shadow from BLACK to one of the shades-of-grey in RH-5.
I PAUSED on migrating to -6 awhile back, as too many of these kinds of issues were still causing too much pain. I MAY check it out again soon,
but for now …
it remains RH-5/Rendered Mode
NEON set to 20seconds for a DENSE scene and 15 secs for anything “Moderately dense” or less for absolutely STUNNINGLY SHARP and clear results that I can manipulate, within the limitations of the NEON operating mode…
RHINO-Render sometimes when it becomes necessary, but otherwise its -
90% Rendered (Shaded and Ghosted in there too - as needed) Mode,
when I want as near ZERO seconds per frame as I can get in a BONGO-2 Render, I stick to Rendered Mode or Ghosted, as appropriate.
If a FEW seconds are ok, say 15-30 seconds ( SECONDS !!! ) delay per frame is allowable, then NEON may offer the image result I need in my animation.
IF I need to go to RHINO Render and can survive ~60 seconds per frame, I’m still WAY ahead of my competition, offering them check-run animations by tomorrow afternoon, as opposed to RH-6 Raytraced or worse, requiring sometime near the end of the week or into NEXT week, with only marginal results.
Hope these tips offer some help -
