PrepKit

A Godot plugin for streamlined 3D asset processing, including mesh library generation, automated GLB → scene conversion, and customizable file mapping workflows.

PrepKit helps you:

• Batch-convert GLB files into Godot scenes
• Optimize materials by reducing duplicates
• Build mesh libraries from individual assets
• Define custom asset processing rules with mappers

Installation

1. Clone/copy the plugin to your project's addons/prep_kit directory
2. Enable in Project Settings → Plugins

Usage

Build Mesh Library: Right-click directory with GLB files → "Build Mesh Library"

File Mapping:

1. Right-click directory → "Create Map Config"
2. Configure the _prep_kit_map_config.tres file (mapper settings, prototypes)
3. Right-click GLB files → "Map Files"

Custom Mappers:

@tool
class_name MyCustomMapper
extends PrepKitMapper

func is_valid_path(path: String) -> bool:
    return path.ends_with(".my_extension")

func map(path: String, map_config: PrepKitMapConfig, directory_config: PrepKitConfig):
    # Your custom processing logic here
    pass

Requirements

• Godot 4.4+
