I worked on this tutorial level for the game Eximius: Seize The Frontline. This level is made specifically to teach players the basic movements and the shooting mechanics of all of the weapons in the game.
All of the modular pieces including the pillars, floor panels, ceiling panels and walls were modeled in the 3D modeling package and brought into the engine to be built. To save time on texturing and UV mapping, the meshes were textured using tiling textures and trim sheets. I made a master shader that allowed me to control the albedo, roughness and metallic values in engine. A few grunge maps were used for the roughness variation on the meshes. I also added mesh decals for the labels and smaller details like screws and bolts.
Here are the other artists involved in bringing the level to life:
