Made with blender and textured in substance painter with pbr textures. Contains 6 objects. All objects are in same file. Origin of each object is in center of objects mesh.
Mesh contains only polygonal quads and tris. Mostly quads. No ngons used!
Every object has own textureset and every textureset contains basecolor/albido, metallic, roughness and normal maps. Texture format is png. There are no complex blender materials used (only textures) so you can get same results with other renderers. Just place textures and render.
Every object and texture is named correctly, so usage is easy. Metric system used !
