Modular Sewers Environment, made for Unreal Marketplace,
Contains Around 200 Assets, Interactive Doors, Procedural Pipes and Wire + Light's System, that helps to build Level very easily.
Most of the materials contains Vertex Paint channel to draw some Dirt and Moss, where its needed.
Using Dirt Masks and Second UV channel, i made some AO blended with Dirt that works perfectly with Tiling Materials.
