Just a screenshot promo for the old Poser Glowworm or Gloworm for Poser, a sophisticated ‘no longer available’ Python script for doing multipass renders and glows. This is just so that curious folk can see what it once offered…
Update: now in the public domain with downloadable source code.
A Firefly method was disovered by Connatic in 2014 and polished by 3dcheapskate (same forum page, lower down)…
From here, light intensity was further set to 0.02 and the edge blend-inner color to 192,192,192, outer to bright green.
So it can be done, but with several off-putting limitations:
* A fiddly set-up for ordinary users. No script to handle it all automatically.
* Not all that controllable, re: needing to carefully balance several ‘drivers’ of the effect in the scene.
* Only appears to work if the light has a ground in the its background.
* Can’t seem to have a surface emit the light, only the point light.
This is Firefly of course. Which can do emission that affects other objects, as can SuperFly, by ticking “Emissive” and rendering with “Indirect Light” ticked. SuperFly can’t yet do ‘spillover’ or ‘bloom’ glow.
