Help with Rendering (Reality)
So when I set the scene, in the visible viewing area, and even with Daz renders... the lighting looks good. But when I use Reality, everything is blown out (over exposed). It makes setting up lights within Daz hard because I feel like I'm constantly backtracking. Does anyone else deal with this?
What's the best way to set my lights and prep / adjust for Reality (beyond going back and forth between Reality and my scene in Daz)?
Halp! :)
Edit: It's weird. It doesn't matter how many lights I have on, or where, or how I adjust them in Daz (or Reality), the renders (within Reality) are all looking the same (based on the inital few minutes of rendering). I even have a subtle, wide blue light (for a sci-fi scene) that isn't showing up (blue) in Reality. What am I missing here?
Edit 2: added attachment showing scene in Daz (dark, subtle blue ambient light and the start of render in Reality (overexposed, no blue, etc.)

Reality is just an interface between DAZ Studio and Luxrender.
You need to look at the manual for Reality and Luxrender to see what to do with the lighting. Luxrender is an unbiased renderer, which usually only uses one Distant light (The Sun) and it can be adjusted from within Luxrender itself.
There are other 'Mesh' lights that you can use within Luxrender which work much like the Uber Area Lights.
What lights are you trying to use, and I'll see if I can help?
You do not set up the lighting in DAZ Studio, and then try to use that in Luxrender, Lux works in an entirely different way, and you really need to look at the Reality manual and the Luxrender manual as well.
Ok, I see now. Only setup lights in Daz if you're using Daz to render? Otherwise, just use the sun within Reality?
Is that basically the gist?
Hi
It shouldn't be blurry like that, it looks like the Daz camera is out of focus.
1- I would check in daz if the depth of field is active (camera parameters)
2- I would check in reality (camera tab) if the depth of field is active.
Deactivate it to see if the problem comes from here.
If you want it anyway, try to set the depth of field in studio so your subject is not out of focus.

Oh, cake. That's only how it's rendered after a minute or so. I know it will eventually render the focus, but I posted the side by side to show the lighting descrepecies between my Daz setup (dark) and Reality (overexposed). That's what I'm having issues with.
It still looks very very blurry. When i start the render, it's not sharp but you can see the edges of stuff...
still, for the lights, you have a "light tab" in lux render (not reality) and you can adjust each light you have in the scene to match your desires
Sometimes true, but it is possible to set up lights in D|S if you know how those lights will be converted when the scene is handed over to LuxRender. The problem you're having is that lighting a LuxRender scene is just so different, you have to learn a complete new way of thinking about lights. The two plugins we have right now, Reality and Luxus, both do a pretty good job of these conversions, but they have limits.
Gotcha. I'm just going to do my lighting in Reality going forward since, apparently, Daz can't inherently achieve that same level of render.
Thanks guys!
You were right all along; it WAS blurry! It's because I had the f/stop to like -50 in Daz and Reality defaults to 1.8. I went into Daz and set it to 1.8 and, sure enough, she wouldn't be in focus. You're good!
Edit: So I turned off ALL lights in Daz, added Sunlight and positioned it (to look dimly lit within Daz), then started a render in Reality and everything is pitch black. Man, how do people use this plugin efficiently!? :)
Edit 2: It was rendering pitch black because the sun was BELOW the scene (under everything). I guess it has to be physically ABOVE somewhere in order for it to render properly (within Reality).
One thing you have to remember about Reality and Luxrender is lights do not work the same way, Reality comes with some lights for Lux that work very well, Set your lights for the camera, All the controls in Lux work just like a camera, I have just started with it as well, it is taking a bit to get used to but I am really liking it , The amount of control over lighting is crazy, With Reality you can turn anything into a light source, Those scenes in Daz that have light fixtures ? that you always have to put a radial light onto to make it look like it is a light source ?, In Reality you can select it , then turn it into a light and make very realistic lighting. Go to the Reality 3D website, they have a couple of good tutorials on lighting in Luxrender using Reality.
I know this thread is kind of dead now, but you have to remember in reality, light is "real". DS lights do not react as real lights. that is the difference. I love reality. I use it all the time, and hardly 3delight. I tend to use soft boxes for my scences. 2-3 soft boxes, a couple more scaled up mesh lights for lighting backgrounds. you have to go back and change the light settings from temp to rbg or presets to get lights like in your viewport.
I have had terrible results so far trying to use Reality/Lux. In searching for solutions I came upon an article which while too long to post here had this to offer:
"AMD CPU's are just useless with LuxRender since AMD doesn't support AVX instruction sets and others like Hyper-threading..."
My CPU is an AMD 4 core and if this is correct then both Reality and Lux are pretty much useless to me. Any one else finding this to be an issue?
Paul try asking your question over on the reality forums, Paolo is usually very quick to answer: http://preta3d.com/forums/index.php
Reality also supports gpu rendering so that might be an option for you.
