I reworked the wetlands, pretty much redid everything and added a large clusters of detailed procedural forests to the already massive 400 sqkm map. Everything inside the map is 100% procedurally generated, running in real-time in UE4. Everything was created with custom photogrammetry models and surface scans created in MetaShape. Foliage assets where created in 3dsmax, little procedural work in Substance and lots of materials, procedural setups in UE4.
