Why is Blender wasting time rendering transparent areas when “film transparent” is activated ?
Is it possible to cancel rendering tiles on transparent areas and move to the next one until it meets an object to render ?
Renders could speed up by 200-300 %
Also, is there an algorithm that could average a tile between similar pixels so that on flat colours or similar areas, the tile renders speed up making an average between 2 pixels to create the 3rd one ? (pixel or tile)
I remember that modo faced this problem many years ago and found a solution through what i just explained above.
Hope tit would help.
