Features

Pixel Art Rendering

• Real-time 3D to pixel art conversion with customizable pixelation (8-800 pixels)
• Color quantization with adjustable steps (2-32 colors) and 8-color palette support
• Advanced shader effects: edge detection, sharpening, dithering, and outlines
• Post-processing controls: HSV adjustments, contrast, gamma, and brightness
• Specular and Normal map export

Animation & Export

• Frame-by-frame animation export to PNG sequences with progress tracking
• Flexible export settings: custom frame ranges, variable FPS (1-120), resolution scaling
• GLB/GLTF model support with animation playback controls and auto-refresh detection

User Experience

• Intuitive interface with organized control panels and real-time preview
• Preset configurations and console logging for detailed feedback
• Export management with custom paths, filename prefixes, and batch capabilities

Quick Start

Installation

1. Clone and open:

   git clone https://github.com/bukkbeek/GodotPixelRenderer.git
   cd GodotPixelRenderer

2. Launch in Godot:

   • Import project.godot
   • Press F5 to run
   • Select PixelRenderer/PixelRenderer.tscn if prompted

Basic Workflow

1. Load Model: Click Load Model and select GLB/GLTF file
2. Configure Effects: Adjust pixelation, colors, and shader parameters
3. Set Camera: Position and frame your model using camera controls
4. Export: Choose output directory, set frame range/FPS, and export PNG sequence

Key Controls

• Animation: Play/pause/stop buttons with loop toggle and frame range selection
• Camera: XYZ positioning, rotation presets, and zoom controls
• Effects: Pixelation slider, color steps, palette mode, and post-processing
• Export: Directory selection, resolution scaling, and filename customization

Technical Details

Project structure

• PixelRenderer.gd: Main controller and export system
• models_handler.gd: 3D model positioning and camera controls
• models_spawner.gd: Model loading and animation management
• pixel_material.gd: Shader parameter management
• PixelArt.gdshader: Custom pixel art rendering with Sobel edge detection and Bayer dithering

Export System
