the scene.

checkpointRender Off For EXR renders only, including VSHADs. If enabled

Katana watches for an Arnold render to be killed, and

copies intermediate data in EXR files in the output

render location. If enabled on subsequent renders, the

unrendered portions of the current render, are

rendered and stitched together with the previously

rendered image data to produce the final frame.

Note: Does not work with DEEPSHADs

assInclude N/A Path to an ass file which is sourced immediately prior to

rendering.

assIncludeWhen at start up If a file is specified in assInclude, determines when the

ass file is included (which is relevant if the ass file

contains light linking information).

reference_time 0 Sets the time at which SSS point clouds are computed.

Also, when disabling motion blur with the ignore_

motion_blur option the time specified by reference_

time is used instead of the shutter open time.
