Render AOVs only

[ceen]

Hi,

is there a way to output AOVs only without rendering beauty etc? Since they are calculated in sync with main rendering is there a fast output way other than put like 1 sample into pathtracing etc?

This is probably not possible because render passes are generated during rendering as side product. Technically beauty pass is a mix of all other AOVs. But simple masks should be generated without the need of final rendering - as it is in CPU renderers.

Yes most likely. Do you know how to render layer masks and MatID, ObjID etc only?

You can't have anything without main render buffer. Just use maxsamples low as giving acceptable outputs.
