PhotoView provides two ways to preview renders: in the graphics area (Integrated Preview) and in a separate window (Preview Window). Both methods help you assess changes quickly before performing a full render. Because updates are continuous, you can experiment with controls that affect rendering without fully understanding the purpose of each control. When you are satisfied with the settings, you can perform a full render.
The preview updates continuously as you change the model, refining the model incrementally. Changes to appearances, decals, scenes, and rendering options update in real time. If you change portions of the model, the preview updates for those portions only, rather than for the entire display.
