Reality is the most advanced rendering solution for creating photo-realistic images right from DAZ Studio or Poser.
With Reality you gain unsurpassed physical accuracy, a workflow that is tailored for the 3D artist, and the ability to render your image without blocking DAZ Studio or Poser.
And with Reality you can change lights and exposure interactively, while the render runs.
Why settle for anything less?
Definitely a plug-in worth investing in.
