Controlling processing in Render Settings

- [Instructor] Let's adjust a few key render settings…to control, among other things,…how Arnold uses the computer's processing power.…Open up the render settings dialog.…We can get to that through the menus.…In the menu sets, choose rendering.…In the render menu, render settings.…And there's also an icon on the status line up here.…It's a clapboard that has a little gear on it,…display render settings.…

Let's go over to the system tab.…And we start off with the Maya integration section.…The most common switch you'll want to throw here…is progressive refinement.…This gives an immediate low-fidelity preview…of the entire frame.…The finished high-fidelity tiles of the rendering…are called buckets.…The progressive refinement switch…determines whether or not the low-fidelity preview…is calculated before the finished buckets.…

If we turn this switch off,…then production renders will be a little faster…because the preview isn't being calculated.…In the render settings section down here,…we see some more options.…By far the most important one is auto detect threads.…
