An Unreal4 project that I've had in the works for a few weeks now. I wanted to challenge myself to use more procedural materials in UE4 so I'm using a lot of tiling textures with materials that apply rust, moss, and wetness procedurally on top of them using worldspace and masks I baked out of Substance Painter, used in combination with vertex painting and decals. I also toyed around a bit with UE4's cables and edge dithering in some materials.
Modeling done in Maya and zBrush. Textures in Designer & Painter. Everything else in UE4.
