This is something I’ve been playing around with for a few days - a modular treehouse fortress. I started this specifically because I couldn’t find any good assets to use with Dungeon Architect. Also pictured is the Redwood Forest and some assets from the Modular Wooden Prop Pack for filler while I develop.
It makes use of depth fields to draw enhanced AO, moss, leaves, dirt, etc.
Performance is good, I’ve been keeping this scene at 120fps on a GTX 980Ti.
