It comes with lights, and I thought this would be a good way for me to light a scene quickly, assumed it was more of plug and play. However, I had to adjust the f stop and iso to be able to see the character, and its still dark. And the dome itself is showing gray. Is there a good 4.9 tutorial for these skydomes and what settings you need to change? I am a noob, and this really confuses me..

Me too! I was about to start a thread about the genral settings and the RULES for rendering environments + skydomes + lights etc...
I know there's a relationship like - if you have a skydome, you set render/environment a certain way. (Dome + scene or Dome only or...)
It's like the Skydome is actually blocking out the sun or something,
I can'rt remember the rules, but I have that too, every so often, I mess with those settings or when I kit bash environments and there's a conflict.
Right now I'm battling A Planet-X1 easy environment and it's dark as hell or black or blank .png.
I'm mixing sets and it's not going well. lol
We both need help right now.
I don't have this set but from the shop description I would expect that the actual dome is for the 3 Delight Version only
The HDRI is for Iray & would be loaded from an Iray Render Settings Preset
The read me should help you find the bits you want
http://docs.daz3d.com/doku.php/public/read_me/index/31867/start
Just a quick test with the First Light Render Settings, with default tone-mapping.
I've set to each render setting and none helps, scene only, done scene etc. The only thing that has helped so far was chaging shutter speed and ISO. but still dark and no background.
That's what I'm looking to do. I used their settings..also changed the iso and shutter speed.
Re you using the right settings for the render engine? There are separate settings for 3Dlite and Iray.
I guess I'm too much of a noob, the readme didn't help, and the creators page talks about Daz 4.8 and the additions he mentions are for without Iray. I am lost..
Yes, I used the Iray settings, unless I'm doing it wrong? I see them on the left side under render settings and I double click on the IRAY one. If I render in 3DL the background looks good. So..it's iray related.
If you render in 3delight using the Iray settings? Are you sure you don't also have the 3Delight set loaded, which is a modelled "dome" that will block the Iray environment map? Loading one won't clear the other.
I figured out my problem, at least mostly. For those using these type of HDRI enviornments, I was assuming (you know what that does) that the dome was supposed to be used and make sure the map was in the enviornment map. However for IRAY, you just have to use the image supplied and put it in the enviornment map. No dome. Render dome and scene with dome on.Now I'm just messing with lights supplied with the pack to see if I can get the look I'm going for. I can't believe this took me hours of putzing with all the settings and reading a lot of articles. It sunk it though. Finally. I've learned a lot in the past week I think tho. and these type of enviornments render SUPER fast. wow. Thank you everyone!!!
Yes, those hdr maps and the dome/dome+scene lighting can give fast results. However, in my own experience, using the iray dome for lighting usually give some noise or grain in the 'shadow areas' on figures with 'skin' (or similar material-settings) that does not seem to want to go away. It can be seen in your image also (best visible in the shadow part of the neck and cheek). Some use a solution in the form of rendering in twice the dimension, and then reduce size in an image editor with some blur or other settings to get rid of the effect..)
Hmm, I don't notice that grainyness, but I am new to Daz so maybe I don't know what it "should" look like. I'll try what you said next time and see how that looks. Thanks!
Usually it isn't very noticeable if you don't look -too- close, and at 1st - in my own renders - I thought it to be a .jpg compression artifact (loss of quality). But as I'm experimenting with Skydomes and Sun-Sky or HDR lighting, I notice it more and more. (And only you can decide for your renders if it needs correction or not..)
Thanks for explaining..will try what you said and compare. I wasn't zooming in that close :-)
