‘Animation’
This toggle enables the rendering of the entire animation. When the "Render Mode" in the "Output" panel (see [Render Mode], page 48) is set to ‘Save RIB’ then RIBs for each frame will be saved to disk. If the RIB filename remains the same from one frame to another, the data of the current frame is concatenated to the file. This toggle is off by default.
‘Frame Range’
If the "Animation" toggle is on, specifies the range of frames to render (bounds are inclusive). The default range is [1..1].
‘Increment’
Specifies the increment to use when going from one frame to the next in the frame range. For example, if the frame range is [1..6] and the increment is 2, only the following frames will be rendered: 1, 3, 5, 6 (note that the first and last frame are not skipped). The default increment is 1.
