I was playing with the Mega Terrain Swamp Lands by and Kindred Arts and RavenLoor for the first time, and thought perhaps my Necromancer guy could show off his Horizon inspired Face Paint here. I did this in a Twitch stream, using Aloy as a reference. The landscape itself is a great starting point, but I thought my guy needed somewhere to live too.
Julia discovered these cute little procedural generated houses by Watabou, so I tried one of them as a background object: https://watabou.itch.io/procgen-mansion
It worked out great! The geometry of such models is often not fantastic, but I found a little add-on called Bmesh Clean that cleaned it up nicely (see before/after screenshots). The lighting was done with the HDRI that came with the Mega Terrain, with the addition of two mesh lights to brighten up my man's face a little.
