HI: I have Daz Studio 4.9 and I did a render with three lights. 2spots and one distance light. One V7 and a background figure, one of DM's sets. I have a good PC with 64 gigs of RAM and the Nvidia 4 gig graphics card. It took about four hours to render, which I thought was a long time. Now I find info at Daz that some people were having 7 day renders with Iray and still getting grainy renders. I will try to attach the render. I was very disappointed to get such a result and would like to get a sharp crisp render. Can you help? I am a long-time Poser user and this never happened with firefly, which renders fast I think.
