How to boost AO to keep good quality

Hi, I made window and I wanted to boost AO in ‘small corners’, so I used render layers to boost AO after render but altrough using 256 samples It looks same like I would rendered it in 32 samples. Do you know how to do it properly? In C4D is easier to make this effect.


I “found” “solution” how to do this: I render AO to file and in GIMP flat surfaces (also I select some surface with wand) I paint on white (also I select some surface with wand) and then I apply blur effect, so it isn’t so noisy - also I can change resolution of rendered AO and this will give better quality :wink:
