I was responsible for creating the environments in the VR game Ghost Giant. That includes most of the assets, textures and level building. It was a challenging and fun project to work on. Since the game was aiming for VR and I was the only environment artist I had to find a efficient workflow & an performant artstyle. I ended up using only three materials (Texture Atlases) for almost all assets - One for exterior, one for plants/vegetation and one for interiors. This boosted performance alot and once I had most of the main textures in place it was very efficient to work with - simply UV-mapping objects to existing textures.
