American Desert Town – Store v1.0
What American desert town is complete without a store that sells practically everything?
What do you get?
A total of 8 prefabs, all very well-optimized and PBR-ready. The store is highly customizable. Use the building extensions and the props included in the asset to create a store that is truly unique. The light bulbs can be lit up as well.
Extremely detailed textures. Texture resolutions go all the way up to 4096×4096, depending on the mesh. The store itself uses a single material. Depending on their size, models have either 2 or 3 LOD levels.
