Hey JimmyC- Thanks for responding quickly-
I upgraded to 18.104.22.168 and the problem persisted. After a lot of trial and (mostly) error I think the problem is the form (or primitive) that’s given the uber volume shader cannot be scaled larger than 9x9x9’. I’ve tried all sorts of variables with settings and placement of the lights. It seems as though there is a set amount of particles in the form and making it too big just disperses them too much to get results. The smaller it gets the more intense the effect.
So I’ll just have to shrink all of my scenes down until they fit into the bubble.
Below is my new render in DAZ 4.5.
Oh yeah- During this test I discovered that parented DFormers will not scale with along with its parent shape. To scale my uber bubble I had to export an obj and import it to clear out the DFormers, then I could scale all I wanted.
Update Oct 8 2012- Enlarged Uber Volume sphere to extend beyond floor grid and raised “volume end” to 3,000. The shadow beams are back and viewable from any angle now. The balance of light(s) (intensity settings) and “Density” (uber vol settings) takes a lot of tweaking.
