During live rendering (IPR mode), 3Delight for Maya always renders the current frame and the settings of this section have no effect.
This section controls which frame(s) to render when launching a rendering.
The Frame Range group.
Current Frame Only
If this toggle is set to ON, only the current frame will be rendered. If set to OFF, the frame interval specified by Frame Range and Increment will be rendered.
If the Current Frame Only toggle is off, specifies the range of frames to render (bounds are inclusive). The default range is [1..1].
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.
