if I have to rerender a specific area of a frame, is it possible to define that in the mantra node?
For example if I only need a quarter of a full HD frame, I might specify the pixel area as (0,0,959,639). The rest of the frame might just filled with black or anything else.
However I haven't found this option in the mantra node yet, but I know it from other renderers. Is it also possible with mantra?
