I come from the exact opposite direction - Poser user now learning to use Daz Studio.

An easy way to render is to get a fully set up scene, and render it. Then, change the settings - camera, lighting, rendering, materials etc, and see how the render turns out. That would pretty much give you a feel for what the Poser knobs and dials do (or do not do).

Then once you've familiarised yourself with how to drive the Poser spaceship better, you can start building your own scene and control the scene elements.

Basically this was my approach when learning how to use DS after more than a decade of using Poser.
