I just started using the AoA lights and turned Gamma on with 2.2 and I use 3 Delight but how can you get faster settings. I haven't finished a render using the gamma and I let my render go overnight and it was 7 hours and was just on 75%. What can I do? I can't use Iray because my computer want handle it. Thanks in advance.

Gamma has nothing to do with render speed. Without knowing more about your scene, lighting, and render settings it's hard to give advice - though you might try turning on Progressive Rendering (in the Render Settings pane) if it isn't.
Well the only reason I thought the gamma might be a reason was because I hadn't been using it and renders were a lot quicker and it's the only thing I did different. I wanted to get some realism so that's why I started using it now. What I am doing is just one character with clothes and hair and the 3delight materials no background or anything I wanted to just start with characters and then when I get that add a scene in there. What are the settings or what would be a good tutorial to learn with. I just use the default settings of the light group I select I don't switch any settings that they use. O and I do have the progressive rendering on.
...interesting I have quite the opposite experience with render times using the AoA lights even in fairly "busy" scenes with multiple characters in either render mode. Like Richard mentions Gamma Correction is not really necessary (unless you are using Parris' IBL Master).
What are your system specs and render settings?
I took screenshots is this what you need? @kyotokid
..perfect.
OK, For one you are rendering at a fairly large resolution which may have some to do with the slowness as it does take more memory.
Your bucket size is fairly large which tends to go slower (even though you are using progressive, the final pass still observes bucket size and order). I usually render at a size of 8 and in either mode it goes faster.
Pixel sampling is very high 10 - 16 is usually sufficient for good quality (I usually set that to 12)
Shading rate is awfully low I have it set at 0.20 (usually the lower the number longer it takes).
Pixel Filter, I would set this to 2 for both X & Y.
I also just out of habit set Auto Headlamp to "None" Not sure if this makes a difference in time.
Could you post your system specs (CPU type, cores memory, OS)?
Ok Awesome thank you so much yes here are my computer specs when I bought it it said it was a gaming computer I was getting it for my son but once I got it I started using daz I was told it wasn't good at all.
...there's the other two factors. The CPU has only two cores/threads while the system has only 7.2 GB useable memory.
My old system has 8 cores at 3.4 GHz (turbo mode) and 10,7 GB of three channel memory.
When rendering, the Daz programme and the scene need to remain open so both take up memory resoruces in addition to the memory required for rendering. Now with 3DL I wouldn't think the process would be dumping to swap mode (using the virtual memory partition on the HDD which is even slower). When I was rendering with Iray the process would exceed my system's available memory with some frequency, especially on "heavy" scenes, and the process would then dump to virtual memory (one of my scenes with the Daz programme open takes up 8.9 GB of memory leaving me with 1.8 GB for rendering).
I would try the render settings I suggested and see what happens.
The AoA lights have the option to flag transmapped hair and render them with a lower shadowsample value. With the AoA ambient light that makes a huge difference. You're not mentioning if you did that, if not this is what to do: Select hte hair and go to surface tab, set diffuse strength to 99%. Then select the ambient light and in parameter/light settings, there is an option to set alternative samples to a low value like 16 or less. Then you set the light to use alternative samples for surfaces with a diffuse strength of 99%. You can do the same with the AoA spot and distant light.
And since you say you rendered in progressive mode that means shadow rate settings don't matter nor do pixelfilter settings. Progressive always uses the boxfilter at 1x1. As kk said diffuse samples more than 16x16 is probably overkill in most cases. Raytrace depht can be set to 1 if you don't have multiple reflective or refractive surfaces in your scene.
If you post your AoA light settings we can take a look to see if you can speed up rendering by changing something with those;)
Great I will asap thank you so much for all your help.
