Huge set of PBR mid-to-low-poly container objects (over 270 Unity prefabs), different color variants, shapes, sizes, contains modular (all parts can be exchanged and rotated) and baked variants (single enclosed optimised mesh), includes around 5 LoD variants per model, single material per object set. Also contains several decal images and UV previews for easier decal placing into original textures.
Each PBR material is composed of 4K Albedo, Normal, Ambient Occlusion and Gloss/Specular maps, object polycount ranges from several dozen thousands to a few dozens triangles across LoD meshes.
