I am still new in Cycles development and want to figure out one thing:
if I do not want to render all screen, but just a small part of it - how to specify it?
As I understand Cycles split the screen into tiles and render it separately - so if I specify some list of tiles - I will be able to render some specific part of the screen.
But in cycles binary command line I see params to specify tile width/height, samples count, but not tiles list to be rendered.
Could you please help me to figure out how to make rendering just some specific part of the screen?
Ah, you’re working directly with the Cycles code. Then I think you should be able to set the same values on Cycles’ Camera class, instance variable border (but that’s from looking at the source just now, haven’t tried it).
