This is Tangent Galvanometer: a true-to-life model derived from a physical original. Surface micro-detail is baked into the geometry rather than faked in the shader. The GLB container bundles the mesh and its materials into a single file. Surface maps are baked at 4K so detail survives heavy zoom. It belongs in offline renders where photoreal detail is the priority. It plays nicely with Maya, V-Ray and Octane. Captured reality you can place and render with confidence.
