Missed the first session? You can still register and we’ll send you the session 1 recording 

Do your indoor rendered scenes look like Vicky can’t afford to pay her electric bill? Is your computer tied up for hours trying to get that dungeon render to finish? Is it hard to tell which space marine is which in the firefight in the airlock?

The Iray engine is most effective and efficient when more direct light is falling on the surfaces in your render. This is easily done in the great outdoors with an Iray skydome or HDRI. But interior scenes continue to stump many Daz Studio artists. In this two-part webinar, we will go over tips and tricks to get the quality results you’re looking for. We’ll talk about general approaches and explain how some of the fixes work and we’ll use examples of contemporary, fantasy, and sci-fi scenes to show how they work in practice.
