DESCRIPTION
Overview

Molten Core Asteroid – Procedural Sci-Fi Rock is a highly realistic, fully procedural 3D model created in Blender v4.0.2 and rendered using the Cycles render engine. This asset represents a detailed asteroid rock with glowing lava-filled craters, sharp impact zones, and a rugged surface topology. The model is crafted using procedural shading techniques—no image textures are used—which makes it highly customizable, resolution-independent, and lightweight in terms of memory usage.

This model is ideal for cinematic space environments, science fiction scenes, educational simulations, and real-time games. It can be used to depict asteroid fields, cosmic debris, alien planetary fragments, or even high-energy space anomalies in visual storytelling.

The glowing interiors simulate molten lava effects with animated emission shaders. You can tweak crater size, glow intensity, displacement, and surface details via Blender’s intuitive node groups. This gives you granular control without the need to bake or re-texture the model, keeping workflows efficient and creative.

Key Features
  • Procedural Shader-Based Materials – No image textures; everything is controlled through Blender’s node system for infinite resolution flexibility and parameter control
  • Molten Lava Core Effects – Glowing crater interiors using dynamic emission shaders with adjustable intensity and glow spread
  • Detailed Surface Geometry – High-resolution mesh with deep impact craters, layered fractures, and physically inspired surface noise
  • Customizable Node Parameters – Easily modify crater depth, glow strength, displacement, and roughness with exposed node sliders
  • Modular Design – Easily duplicated and rotated for asteroid belts or space debris clusters
  • Game & Render Ready – Optimized topology ensures fast viewport rendering and clean results in animations

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

Assigned materials
Materials are applied to the 3D model to allow visualize a model's surface properties and appearance.
Learn more
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.
Learn more
UV unwrapped model
A UV unwrapped model means its 3D surface is flattened into 2D space, allowing textures to be applied accurately.
