These are some of the PBR tileable materials I created with Substance Designer, then used to texture "Another Sight" environments in Unreal Engine. I typically exported texture flats out of Substance Designer and then imported them into Unreal Engine.
In Unreal we usually blended the various material layers using vertex painting (the UE4 custom shaders used on the project have been mostly created by Andrea Molino, our Technical Artist).
"Another Sight" is a 2018 adventure/cooperative indie game for PC, PS4, XboxONE and Nintendo Switch developed by Lunar Great Wall Studios. Additional info on the game can be found on Steam: https://store.steampowered.com/app/888630/Another_Sight
