Physics Collision Import Generator
GDScript
Automatically generate physics bodies and collision shapes for 3D scenes from GLB/GLTF files. Select files in the Collision Import Generator dock, choose a shape type, and apply the changes. The plugin sets up import scripts that automatically add physics on each reimport. This captures both the user action (applying via the dock) and the persistent behavior (the import script runs on future reimports). After enabling the plugin (Project → Project Settings → Plugins), a new dock panel named "Collision Import Generator" will appear beside the FileSystem dock.
