I stopped upgrading Poser at Version5, which I haven't used much since switching to Daz Studio. One of the main reasons I switched was seeing what Dreamlight's lighting sets could do. They only work in Daz Studio and I haven't seen the same capabilities in Poser renders. Light Dome Pro is incredible for realistic outdoor scenes. Studio Light Pro is the equivalent for indoor, but can be applied anywhere. Also Mood Master give the artist more options. Since D/S is free, spending a few bucks on these products and some of the other plugins is well worth the investment.
