DESCRIPTION
Realistic Procedural Asteroid – Space Rock | Blender 3D Model

This is a fully procedural and physically accurate asteroid 3D model created in Blender 4.0.2, designed for use in CGI, cinematic renders, space simulations, and sci-fi environments. The model features a handcrafted shader system that simulates natural rock weathering, surface irregularities, and erosion — all without relying on image textures. This ensures maximum flexibility for customization while maintaining high realism and performance.

Developed using Blender's node-based material system and rendered with Cycles, this model provides cinematic-level quality with minimal file size. Unlike traditional texture-based rocks, this asteroid is entirely procedural, allowing users to tweak parameters such as surface detail, roughness, erosion scale, noise density, and color tinting directly in the shader editor.

Whether you're building a galactic battle scene, designing an asteroid belt for a space strategy game, or visualizing planetary impact scenarios for educational purposes, this asteroid is built to deliver production-ready results.

Key Features:
  • Fully procedural material with no image textures
  • Shader-driven surface erosion, cavities, displacement, and edge breakup
  • Surface properties like color, gloss, roughness, and bump are easily adjustable
  • Blender native .blend file includes shader nodes and lighting setup
  • Can be reused for multiple variations by tweaking parameters
  • Compatible with game engines, cinematic rendering pipelines, and educational visuals
Optimized Geometry:
  • Clean and subdivision-friendly mesh
  • Compatible with animation, modifiers, and sculpting workflows
  • No non-manifold edges or overlapping faces
  • Quad-dominant geometry with balanced topology
  • Verified for slicing and 3D print-ready workflows

Vertex Count: 39,684Polygon Count: 39,445

File Formats Included:
  • .blend – Native Blender file with material and light setup
  • .fbx – Game engine and general-purpose compatible
  • .obj – Universal 3D file format
  • .stl – Ideal for slicing and 3D printing

All files are organized in a structured ZIP folder for easy integration and clean workflow.

Compatible Applications:
  • Space-themed games (desktop, VR, mobile)
  • Sci-fi cinematics and cutscenes
  • Planetary visualizations and scientific simulations
  • Educational environments related to astronomy and geology
  • VFX pipelines for space destruction or celestial motion shots
  • Prototyping planetary terrains and asteroid belts

  • Files may be modified, redistributed, or retextured as per license
  • Model license: Royalty-Free (Editorial use allowed)
Why This Model?

This asteroid model was not just built — it was crafted with a production mindset. With fully procedural shaders, artists can push the visual fidelity beyond static textures, while enjoying maximum control. The absence of image textures keeps the asset lightweight and reusable in many different projects.

Compared to similar models that rely on baked textures or high file sizes, this asset offers high realism with lower performance costs. The surface can be changed to simulate everything from a dry moon rock to a glowing meteor, all through Blender's powerful node controls.

Whether you're working on:

  • A stylized sci-fi battle in Unreal or Unity
  • A cinematic flythrough for a film or short
  • An educational solar system demonstration
  • Or even a scientific visualization involving planetary impact simulations

This model provides you with a professional-grade cosmic rock that is reliable, clean, and adaptable to various workflows.

Bring the cosmos to your scene — with full control over how it looks, behaves, and performs.

Geometry
No N-gons
N-gons are polygons with five or more sides which might cause issues in certain processes like rendering or animation. Learn more
No faceted geometry
Faceted geometry uses flat surfaces without smoothing, which can look unrealistic on curves.
Learn more
Manifold geometry
Manifold geometry ensures all surfaces are properly connected, avoiding issues like edges shared by more than two faces.

Textures & material
PBR textures
PBR textures simulate how light interacts with materials, making the model look realistic under different lighting.
Required PBR textures:
- Base Color
- Roughness
- Metalness
- Normal

No embed textures
Embedded textures are stored inside the model file, increasing its size and sometimes causing compatibility issues.
Learn more
Square textures
Texture aspect ratio is the width-to-height ratio of a texture. Expected texture aspect ratio: 1:1

Power of 2 texture sizes
Textures with dimensions in power of two (e.g. 512x512px, 1024x1024px) are used to optimize performance and memory usage.

UVs & naming
No UV overlaps
UVs overlap when multiple points on the 3D model's surface are mapped to the same point on the UV island causing texture stretching.

UV unwrapped model
A UV unwrapped model means its 3D surface is flattened into 2D space, allowing textures to be applied accurately.
