I made a simple stress test file with 1321 subd objects.
First I made the donut object, then another with higher density, removed some faces and offsat it both ways to make the glazing and threw some sprinkles on it, and blocked the finished donut.
(I used a custom script for mesh populating that I made earlier that populates a mesh with a block on random top intersections while randomly rotating the block around Z)
Then duplicated and rotated that two times. This resulted in a file with 1320 subd objects. + the tray of course, which is another subd object. Added two rectangular lights and lowered the environment hdri exosure.
Hope you like it and here is the file if you want to take a look.
(It’s actually only 4 objects in the file, one donut, one dripping coating, one sprinkle and one tray)
