Description
"Lighting normalized," um, lol, I spent the weekend re-doing the lights on this set from a no-shadows overhead infinite/ambient light (plus a pair of others), to point lights carefully placed in front of the actual light panels of the set. Poser has a huge light pollution problem with the default settings and light types, and you really need to do a lot of work setting these to quadratic falloff, setting ending ranges, and even naming them - otherwise the pre-Poser 8 lights just keep bouncing and bouncing (or the escape into the ether if your set isn't sealed) and you get this really harsh over-lit effect.You can see the nice highlights on the figures in the background, that white panel light is lighting up their sides and then fading off. We have softer highlights on the engineer's back from another set of panel lights, softer since the falloff is set to quadratic (which is how real lights work). Since I turned the red emergency panels to normal white ones, I can get away with this lighting shift.
Lighting can take up one-person's entire time, just like materials. Great lighting takes a lot of time, a lot of time, since you are experimenting, rendering, and doing a lot of test renders to get the look you want (combined with the materials).

I hear you on the lighting. I'm looking forward to getting a new PC in future with a better video card setup so at least the test renders won't take so damn long.

I have had to tweak my setup a whole lot just to get decent speed on OpenGL previews, once you get four or more clothed figures in there you start to lose a lot of responsiveness. I hide a lot, set background items to flat shaded, and turn off hardware shadows just to get some of these scenes workable.
And yeah, lighting. If I did this work in a production environment, I could see one person just devoted to lighting sets - all day every day. Beyond 'room standard' lighting for a scene like this, you can light it so many different ways for different looks. And then materials come into play if you want some of the panel's 'off' - and if you can't do that you turn them all off you start playing with new geometries for the light planes you want on, and so on.
Also, one of the most tricky parts is you need characters in there to judge lighting, I have sets that come with preset lights and they look beautiful in the previews and even final renders. Once you put a character in there? Ouch, they get blown out or just look awful and I am back to square one relighting the entire set.
And using preset iRay lights is cheating. Set up a whole lighting rig with point lights, emissives, distance no-shadow fills, or spots on actual light sources (and tweak individiual settings) and learn a whole heck of a lot.

Interesting, I don't find additional figures themselves to be an issue in terms of making Daz Studio unresponsive, nor clothing per se, but for me the system gets slowed down by some clothing items and by some sets. I had a set a while back that I had to keep invisible until the final render, it was so bad.

Yeah, I have two peculiarities about my current workstation config: ATI FirePro Card (chosen for OpenGL speed for Vue) and I am working in Poser (for this series) for specific technical reasons (I will get into those reasons in future pics). Studio is great with multiple figures, Poser is a bit less so. Poser's hardware preview shadows with 4+ figures (at about a gig of scene file size) kills my frame rate - I need to look into that, possibly a driver or some other setting.
Then again, if I pre-light my scenes and preview render, why do I need hardware shadows? I never really use them, and I prefer zipping around with my 3d mouse at high speed through the scene to check trouble spots. Frame-rate when I work is king.
The FirePro has been a good non-iRay card for Vue and Poser, and I was waiting for the current generation of nVidias to start shopping. Right now there's no need, but I can see upgrading that sometime down the road.

...and the hologram is cool too, I so missed talking about the obvious. You learn your render types and materials, and you can do very slick effects like this easily.
