Neptune 16K Photorealistic Low-poly 3D model

Overview

The asset combines an optimized mesh with 16K physically accurate equirectangular textures, seamlessly mapped without polar distortion. Designed for film, games, VR, AR, and fulldome environments. Ready to import and render immediately, with all materials embedded. Includes a volumetric atmosphere for ray-traced engines and, in Unity, a custom atmospheric shader that simulates sunsets using color gradients and Fresnel effects without requiring additional setup.

Scientific Background

This 3D representation of Neptune is based on scientific data regarding its chemical composition and atmospheric dynamics. The physically based textures incorporate visual features of high-altitude methane ice crystal clouds, derived from real images taken by Voyager 2 and the Hubble Space Telescope.
