I wanted to take my Artillery Mech design that was built and rendered in Modo and bring it across to UE4 to recreate a similar set up.
I used Quixel Mixer to generate all of my tiling materials and then drove a smart shader in UE4 with simple Convexity and Concavity masks to blend between them, this is so that I can build the asset quickly with a very small amount of unique textures but also keep the texel density very high.
This means I can get a texel density of 1024 per meter without loading any textures above 2048x2048.
The asset also has no baked normal maps as it's all been modelled with face weighted normals and then very small details are added through normal decals.
