Prototype Sprite 3D

This addon for Godot 4 provides a PrototypeSprite3D node that helps developers quickly create and manage prototype textures for 3D sprites.

It includes features for generating placeholder textures with grid overlays, exporting templates for art pipelines, and importing final artwork.

Usage

Basic Placeholder Generation

Placeholder generation can be used to quickly block out sprites in a scene that are sized correctly for your 3D world in meters.

1. Add a PrototypeSprite3D node to your scene
2. Configure the desired world dimensions (width_meters, height_meters)
3. Choose a color and enable/disable grid overlay
4. Set a PrototypeCanvas resource for texture resolution and settings
5. Click "Generate" to create the texture

Canvas Resources

The PrototypeCanvas resource defines the resolution and properties for exported art templates. See the canvases/ folder for pre-configured canvas resources optimized for various 3D sprite types.

Canvas Templates for 3D Sprites

Exporting Templates for Artists

1. Set the export directory path
2. Click "Export" to generate a template file using the current texture at the specified resolution

Importing Final Artwork

1. Set the import file path to your final artwork in a supported image format (e.g., PNG, JPEG)
2. Click "Import" which will replace the placeholder texture with the final art and adjust pixel size accordingly
3. When satisfied, change the node type to a standard Sprite3D for production use

Requirements

• Godot 4.5 (might work with earlier 4.x versions)
