I have a quick question. I have an issue in DAZ Studio 4.5 Pro. I noticed that my lights aren't making the characters cast appropriate shadows. I was just playing around with things and exported some things to Bryce 7.1 and when I rendered there, I noticed they were casting appropriate shadows for the light, which made it stand out that they weren't when I did the render in Studio. However, when I exported to Bryce, the character's colors didn't come over and some of their hair props were missing. Is there any light I can use in Studio to get the character's to cast shadows on themselves and other characters? Or a way I can get all the settings from skin tone and hair props to export to Bryce so they'll render correctly there? Thanks for the help!

Thanks for all the info, i was having so much fun playing with Daz Studio i never noticed that no shadows were being cast, Brcye and Vue automaticaly cast shadows from light sources.

Lights in Studio have a 'cast shadows' parameter, which for some I believe default to off so that things render faster. Obviously, you want to set those back to on. But I don't really know much about the way 3Delight renders, since I always export my scenes to LuxRender and use that to render them. LuxRender, being a physically un-biased renderer, always gives you correct shadows.

It worked! :) It took me a while to find a light that it would work on though. I tried a spotlight at first, but it didn't seem to work, then I tried a distant light that I had. Eventually I just inserted the lights from the Fiery Genesis tutorial and turned all but one of them off, then changed the settings as you described and made the color white. Now my characters are casting shadows! :) Yay!

You can choose individually for lights and objects to have a shadow. It not only makes render time shorter, it allows you also to light up a scene with "invisible shadowfree lights"

It sounds like you need to adjust your shadow settings.
Your main light should be behind your camera.
eg. spotlight on your character- adjust ray length so the ball touches character-ray traced shadow- softness .5 - 2, - bias between 3 and 4. Hope that helps.
As for exporting.. Daz and poser assets do not like other platforms. The process is more work than it's worth. I spent a month trying with 3ds.

This actually brings up a question I've had for a while. What *exactly* is the shadow bias and what does it do?

The bias is what lines the shadow up with the object and "attaches" it to the right point. I got this from a tutorial when I first started and it worked so I've stuck with the 3.5 to 4 ever since. It takes a lot of experimenting, I'm still trying to get the perfect light after almost a year..:P

Isn't shadow bias only important when using shadow maps?

Phew, I was starting to think I'd learnt it all wrong.
