Whenever I make a new save and go looking for sledgehammers, it just bugged me how occlusion works. I'd like to suggest when you revamp the occlusion system (or if you can easily update it) different occlusions for different scanarios. from my sample photo, it looks lake game uses right method of occlusion, but it would look neater if you followed the left method of occlusion for general purposes, but you can apply the right method of occlusion for building/looting a container like so.
Aside from suggestion, it would be great to add occlusion to the other side which there is none currently. (pz1.png)
