Procedural Planet Generator 2.0

A dependency-free Blender extension that creates editable procedural planet systems from native geometry and shader nodes.

Compatibility

• Blender 4.2 or newer
• Tested with Blender 5.2 LTS
• Eevee and Cycles
• Windows, macOS, and Linux
• No external textures or Python packages required

Installation

1. Open Blender.
2. Choose Edit → Preferences → Extensions.
3. Choose Install from Disk.
4. Select procedural_planet_generator-2.0.0.zip.
5. Enable Procedural Planet Generator.
6. In the 3D Viewport, press N and open the 行星生成器 tab.

Quick Start

1. Position the 3D Cursor.
2. Choose a planet type.
3. Set the seed, radius, and quality.
4. Adjust surface, ocean, clouds, atmosphere, rings, and moons.
5. Click 生成行星 / Generate Planet.
6. Optionally create the deep-space presentation scene and press F12.

Planet Types

• Terran: terrain, oceans, clouds, and atmosphere.
• Gas Giant: turbulent bands and equatorial flattening.
• Ice: reflective ice, relief, fissures, and craters.
• Lava: volcanic terrain and glowing cracks.
• Ocean: layered deep-water shading and clouds.
• Barren: rocky relief with crater bowls and rims.
• Alien: extraterrestrial colors with optional clouds and atmosphere.

Main Controls

• Surface: radius, quality, texture scale, detail, bump, terrain height, and crater strength.
• Ocean and Clouds: independent glossy ocean and cloud shells.
• Atmosphere: color, height, brightness, and limb sharpness.
• Rings: inner/outer radius, tilt, opacity, colors, and procedural bands.
• Moons: up to 12 cratered moons with optional orbit guides.

Generated Structure

Each result is placed in a dedicated PG_Planet_* collection. A root controller parents the surface, ocean, clouds, atmosphere, rings, moons, and orbit guides. All meshes and materials remain normal editable Blender data.

Performance

• Use Low quality while exploring seeds.
• Use Medium for normal work.
• Use High for final close-up renders.
• Reduce moon count if generation is slow.

Troubleshooting

Panel missing: enable the extension, open a 3D Viewport, press N, and select 行星生成器.

Planet looks dark: use Material Preview/Rendered mode or create the included presentation scene.

Eevee/Cycles differences: adjust ring opacity and atmospheric brightness for the selected engine.
