Only applies to Blender Batch style. This determines how many frames each Blender Batch process will render. For example, if you are rendering a 10 frame sequence, a frame chunk setting of 1 will produce 10 separate blender batch processes, whereas a frame chunking setting of 5, will produce only 2 blender batch processes, with each rendering 5 frames.  Frame Chunking, with the Persistent Data option turned on, can help speed up batch renders.

Only applies to Blender Batch style. If this is turned on, all RenderMan Displays options will be ignored and only the final composited image will be saved. If off, then any compositing operators in the Compositor is ignored. If the composited image needs to be denoised, turn on the Optix denoise option.
