I learned this method from jag11 on the DAZ3D forums, who is thanked for permission to use it in this tutorial!
In 3Delight there's no way to create atmosphere or godrays (the rays that are visible when light passes through dust or particles). There are products to facilitate (one of them mine), but most are either not the easiest to use or ultimately just a faking of a feature the engine lacks. Many artists use postwork instead.
DAZ Studio 4.8 Beta's new Iray engine also lacks a native mechanism for creating atmospheric volumes - but it can be easily convinced to produce them! They will come from your lights and react to objects in your scene. I did a test image of Jack Tomalin's Chapter House Iray scene (free to Plat Club members
Why you should use a floor with Iray(lighting tut)HDRI maps are wonderful things. HDRI or IBL is using an image to light your scene. Here's a great resource for free maps to play with. If you need a further explanation I suggest googling for people who can explain it much better than I can = /Why you should use a floor with Iray(lighting tut) by Pleblu
Once you got your searching on and downloaded some maps, let's have a chat. Just have a seat, there's cookies and punch over there.
See this here image of a car? That orange one down there? Pretty nice huh? I'd like to own it personally. Love that paint job. That picture behind it is an HDRI from that site I linked above. The only model in this scene is the car. Iray automatically puts in a ground of sorts and that's what those shadows are on. Although it looks weird doesn't it?
I keep seeing a lot of images that use HDRI plus one model sort of floating in the air like this. None of them look right.
Here I plopped in a plane primitive as the floor. Looks better
