Physics Collision Import Generator

This Godot plugin automatically generates physics bodies and collision shapes during the import of 3D scenes from GLB/GLTF files, with potential support for more formats in the future.

Installation

1. Copy the physics_collision_import_generator folder to your project's addons/ directory
2. Go to Project Settings → Plugins
3. Enable the "Physics Collision Import Generator" plugin

Usage

1. Import GLB or GLTF files into your project
2. Open the "Collision Import Generator" dock panel (near the FileSystem dock)
3. Select one or more files from the list
4. Choose a physics shape type from the dropdown
5. Click "Apply Physics" to add physics, or "Remove Physics" to remove it

• Files with physics applied are shown in green
• Use the search filter to find specific files

Features

• Automatically creates StaticBody3D nodes with CollisionShape3D for all MeshInstance3D nodes
• Multiple physics shape types supported
• Preserves existing scene structure
• Uses Godot's import script system to automatically process scenes during import

Shape Types

• Trimesh: Exact mesh shape (best for static geometry)
• Convex: Convex hull approximation (good performance/accuracy balance)
• Box: Simple box shape based on mesh bounds
• Sphere: Simple sphere shape based on mesh bounds
• Capsule: Simple capsule shape based on mesh bounds

Notes

• Physics bodies are created as StaticBody3D by default
• Existing StaticBody3D nodes are reused when possible
• The plugin sets the Import Script Path in the file's .import configuration to automatically process scenes during import
