KeyShot Lux Scripting - Rendering Frame Time Range

Hi,

Under Lux Documentation, there are the following options for Animation Rendering (at the bottom of this post). However, there’s no option to set a Frame Time Range; for example, if I wanted the script to render only frames 20-30 but not frames 1-19.

How do I go about doing this?

Thanks!

Renders frames of the scene to a folder and/or video file.
folder = Folder to render frames to. *
frameFiles = Name of the frame files. The extension dictates the image format (can be jpg/jpeg, png, exr, tif/tiff or psd). (default = “frame.%d.jpg”)
keepFrames = Whether to keep the frames after rendering (default = true).
width = Resolution width in pixels of the frames (default = scene width).
height = Resolution height in pixels of the frames (default = scene height).
fps = Frames per second (default = 12).
videoName = Name of the video file, if any. The extension dictates the video format (can be mp4, mov, avi, or flv). (default = none)
opts = Options specified as a lux.RenderOptions object (see lux.getRenderOptions() ).
format = Image format. Can be one of the following values: lux.RENDER_OUTPUT_JPEG, lux.RENDER_OUTPUT_PNG, lux.RENDER_OUTPUT_EXR, lux.RENDER_OUTPUT_TIFF8, lux.RENDER_OUTPUT_TIFF32, lux.RENDER_OUTPUT_PSD8, lux.RENDER_OUTPUT_PSD16, lux.RENDER_OUTPUT_PSD32 (requires file extension to match).
