Speeding Up Renders

There are several techniques you can use to speed up the rendering process. These techniques are most useful when rendering animations, where you may have a large number of images to render.

You can greatly increase the speed of a render just by using the Preview Render modes.

Here are the percentages of time it takes to a render a scene, containing complex materials and lights, using normal and preview modes.

• Normal Render: 100%
• Fast Render: 41.7%
• Textures Off: 35.4%
• Fast Render w/Textures Off: 8.3%
• Fast, Textures Off, anti-aliasing Off: 2.1%

Lights - TBD

Premium Effects - TBD

Volumetric World - TBD

You can also speed up rendering using these techniques:

• Limit the number of lights.
• Keep background objects simple.
• Limit the number of volume materials you apply.
• Limit the number of transparent and reflective objects.
• Limit the number of frames per second to 15 for QuickTime movies.
• Divide animations into smaller files and eliminate objects that won't be seen in the rendered frames.
• Turn off anti-aliasing when previewing animations.
