There are two ways of using Octane with Daz Studio – through the standalone Octane Render Software or the Daz Integrated Plugin. This article does a great job at explaining the Basic Theory of Physically-Based Rendering. In particular, simulated light bounces around a simulated environment hitting simulated surfaces until it hits the lens of a simulated camara. My understanding of this is that the engine accurately simulates the characteristics of light and it’s interaction with a variety of surfaces. Octane is, like iRay, a Physically Based Renderer (PBR).
