Procedural Spaceship Generator Addon

1. Overview

The Procedural Spaceship Generator allows you to create sci-fi spaceships by combining customizable components, including a detailed fuselage, swept wings, engines, cockpit, and hull details.

Adjust the proportions and design of each component to create different spaceship styles. The random seed system provides endless design variations.

Key Features:

• Procedural spaceship generation.

• Adjustable fuselage length, width, and height.

• Customizable wings, engines, and cockpit.

• Hull details, stripes, antennas, and window lights.

• Tail fins, turrets, and wing engine options.

• Six built-in spaceship presets.

• Custom preset saving and loading.

• Procedural materials, textures, and animation.

2. Installation

1. Download the add-on ZIP file.

2. Open Blender 4.2.3 or newer.

3. Go to Edit → Preferences → Add-ons.

4. Open the small arrow menu in the top-right corner.

5. Select Install from Disk and choose the downloaded ZIP file.

6. Enable the add-on using the checkbox next to its name.

Important: Do not extract the ZIP file before installation. Make sure you select the individual add-on ZIP rather than a bundle containing multiple add-ons.

3. Opening the Add-on Panel

1. Move your cursor over the 3D Viewport.

2. Press N to open the sidebar.

3. Select the Procedural tab.

4. Find the Spaceship Generator panel and expand it.

All Mrs Eliza procedural add-ons share the same Procedural tab.

4. Live Update and Spaceship Generation

The Live Update option is enabled by default. Whenever you change a setting, the spaceship automatically rebuilds after a short pause.

You can also use the refresh button beside Live Update to rebuild manually when automatic updating is disabled.

The add-on maintains a single live object during rebuilding, preserving its position, rotation, scale, parent, and existing modifiers.

Create New: Creates another spaceship at the 3D cursor without changing your existing design.

Randomize Seed: Generates a different spaceship using the same settings. Entering a previous seed allows you to reproduce an earlier design.

5. Creating Your First Spaceship

Follow these steps to generate your first spaceship:

1. Enable Live Update.

2. Click Create New to generate a spaceship.

3. Adjust Fuselage Length, Width, and Height Ratio.

4. Customize Wing Span and Wing Sweep.

5. Add or remove engines and adjust their dimensions.

6. Enable or disable the cockpit and hull details.

7. Use Randomize Seed to explore alternative designs.

When you find a design you like, click Create New to keep it and continue experimenting with another spaceship.

6. One-Click Setup and Presets

The Presets & Scene section provides ready-made spaceship designs and scene setup options.

Click One-Click Setup to generate a complete example using the default Sleek Fighter preset. It also creates materials and can optionally add a ground plane, sun light, and sky color.

The viewport automatically switches to Material Preview so you can see the spaceship's appearance immediately.

Built-in Presets

The add-on includes six ready-made spaceship presets:

• Sleek Fighter

• Heavy Cargo Hauler

• Battle Cruiser

• Stealth Interceptor

• Retro Rocket

• Alien Bio-Ship

Select a preset and click Apply Preset to generate its design. You can continue adjusting the spaceship afterward.

Custom Presets

Save and reuse your own spaceship configurations:

• Save My Preset: Save your current settings under a custom name.

• Load My Preset: Restore a previously saved preset.

• Delete My Preset: Remove a saved preset.

Custom presets are stored in Blender's configuration folder and remain available across projects.

7. Colors, Materials and Textures

The Color, Material & Texture section allows you to customize your spaceship using procedural shader nodes. No external image textures or UV unwrapping are required.

Colors

Create smooth color gradients using four adjustable color stops. Enable Hard Bands for a stepped, toon-style appearance.

The gradient can follow the texture, object height, or surface slope.

Textures

Choose from procedural textures such as Noise, Voronoi, Wave, and Brick. Adjust scale, detail, distortion, stretch, seed, and bump strength.

Layer Effects

Add secondary color effects such as snow, moss, or dust using adjustable thresholds and breakup controls.

Surface Settings

Customize roughness, roughness variation, metallic, glass, clear coat, opacity, and IOR.

Glow and Color Adjustment

Control glow color and strength, along with hue variation, saturation, and brightness.

Random Look generates a new material combination, while Reset Look restores the default appearance.

You can select different spaceship parts and customize their appearance independently.

8. Animation

The Animation section provides material and object animation controls that work with the timeline.

Material Animation

• Flowing Texture: Moves the texture in a selected direction.

• Color Cycle: Continuously changes the material's hue.

• Glow Pulse: Creates a pulsing glow effect. Set Glow Strength above zero to see the effect.

Object Animation

Choose from four motion types:

• Float

• Spin

• Pulse

• Orbit

Adjust speed and amount to control the animation.

Click Stop All Animation to disable all active material and object animations.

9. Settings Guide

The following controls determine the spaceship's shape, proportions, and details.

10. Buttons and Their Functions

The add-on includes several useful actions:

• One-Click Setup: Generates a spaceship using the selected preset, materials, and optional scene setup.

• Apply Preset: Applies the selected built-in preset, including its settings, appearance, and animation.

• Apply Look: Applies procedural materials to the result or selected objects.

• Random Look: Generates a new color and texture combination.

• Reset Look: Restores the add-on's default color, texture, and animation settings.

• Stop All Animation: Disables all active animations.

• Add Lighting & Ground: Adds a ground plane, sun light, and sky color to the scene.

• Save My Preset: Saves your current configuration.

• Load My Preset: Loads a previously saved custom preset.

• Delete My Preset: Deletes a saved custom preset.

11. Tips for Better Results

• Long, narrow fuselages with swept wings create fast fighter-style spaceships.

• Short, wide fuselages work well for cargo ships and heavy spacecraft.

• Use Randomize Seed repeatedly to explore different designs.

• Click Create New to keep your favorite designs while experimenting.

• Add a Subdivision Surface modifier to create a smoother hull.

• The generated spaceship is already symmetrical. You can use a Mirror modifier in your own workflow when detailing one side.

12. What Can You Create?

The Procedural Spaceship Generator is suitable for:

• Sci-fi game assets.

• Futuristic spacecraft concepts.

• Space exploration scenes.

• Background spaceship fleets.

• Sci-fi animations and motion graphics.

• Concept art and 3D visualization.
