This is a custom, photorealistic, physically-based 3d model with shaders, royalty-free textures and render setup with lighting

Ready to use models

Geometry is all quads (except for cilinder caps) with clean, contiguous topology. Base meshes are low poly with subdivision modifier not applied

Consistency

Each object is UV-Unwrapped and textured and named with relevant english names, multiple-mesh objects are grouped and attached to an empty

Photorealistic shaders

Each material has been created from scratch, using Cycles' node system, according to real world data and light behaviour - You can use the shaders in your creations without having to tweak parameters (or with minimal tweaking)
