You will have to use the Uber-lighting settings for a more realistic lighting in comparison to poser's render. 

First create a distant light, go to Uber lighting in your Daz folder, parent the Uber Lighting "Base" to your distant light by simply double clicking it while distant light is selected. Now select the Uber Lighting "prop" and double click the quality level. You can also select the HDRI setting the same way, Hope this helps!
