Godot Version

Question

How can we control the size and intensity of the Ambient Occlusion? I highlighted an example of AO with a red arrow below:

AO-godot-default
AO-godot-default1196×643 234 KB

To get a stronger shadow area like here (edited in Krita):

AO-godot-stronger

Thank you very much for your help!
