Mostly I export my scenes to Bryce and there I light it up anyway I want, I find DAZ Studio lights are not very good and some renders take forever to render, so my question is:
What is the best tool to use in DAZ to light a scene with all shadows and stuff that don't take forever to render, also render tools if you can recomend.
CHEERS
You kinda need to offer more information. Are you using Iray or 3Delight? Octane? Lux\Reality? What are you trying to do? Indoor, outdoor?
Assuming its Iray, then you need a good video card preferably in the 12GB+ range of RAM. You do not want CPU+GPU rendering enabled. Its slow.
There isn't a generic answer to lighting issues. It depends on what you want to do. And it helps to understand what the pitfalls with rendering in general are.
Its best if you think of rendering as photography. Choose the exposure, and adjust lighting to suit.
Rendering engines are capable of generating imagery with dynamic ranges well in excess of anything we can create in the real world. If you don't have a good lighting solution it will take long and tend to get sparkly.
What I recommend you do is practice some renders from the basics so you can recognize what's happening in your renders. Start with a simple portrait set up. (This is what your basic portrait studio set up is.) One light on camera, one high and behind for drama\hair, and one low and to the other side.
Don't add much for clothes or hair, and just play with it. Then add the other stuff. You should get an idea about performance impacts various elements add, and how the light plays with it. Hair can be, annoying to get right, so stick with stuff you know will render well. (For me OOT hair for the win.)
In movies, there's a reason there are a lot of people working on the lighting. (I remember one extra from Lord of the Rings showing Gandalf holding a mirror below his face just to even up the light on his face.)
In a real render you need lots of light in the scene to even up the contrast from light to dark. I recommend mesh lights, but that's just what I'm used to working with. This is hard to get right, you want the light, but you don't want the splash light on the scene, blah. It gets hard.
Ghost Lights are worth picking up.
Cake One at Daz has lots of Click and Render IBL light sets which I find quite good for simple portrait work.
I'm not really into HDRI rendering, but there are some great tutorials in the Daz forums by MEC4D.
