Eyeon:Manual/Fusion 6/Memory Preferences

Memory Preferences

Occasionally, it will be necessary to adjust the Memory Preferences in order to make the best use of available memory on the computer. For example many artists prefer a higher cache memory for interactive work, because it allows for more frames to be held in memory for faster playback. For final renders the cache memory is often reduced, so that there's more memory available for simultaneous processing of tools or multiple frames at once being rendered.

Caching Limits

Limit Caching To

This slider is used to set the percentage of available memory Fusion will use for the interactive tool cache. Available memory refers to the amount of memory installed on the system, not the amount currently available.

When Fusion's interactive cache reaches the limit defined in this setting, it starts to destroy lower priority frames in the cache to clear space for new frames.

Automatically Adjust In Low Memory Situations

This checkbox will set the Caching to adjust when memory is low. Fusion will notify on the console for any cache purges.

Leave At Least X MBytes

This setting is used to set the hard limit for memory usage. No matter what the setting of the Cache Limit, Fusion will always make certain this amount of physical memory is available for use by other applications.

Normally, this value should not be smaller than 25 MBytes.

Interactive Render

Simultaneous Branching

When checked, more than one tool will be processed at the same time. Disable this checkbox if memory is running out frequently.

Final Render

These settings apply to Fusion's memory usage during a rendering session, either preview or final, with no effect during an interactive session.

Render Slider

Adjust this control to set the number of frames that Fusion will render at the same time.

Simultaneous Branching

When checked, more than one branch of a flow will be rendered at the same time. When running low on memory, turn this off to increase rendering performance.
