Channel Pack Studio is the ultimate texture optimization tool for Unity developers. Pack multiple grayscale textures (Metallic, Roughness, AO, Height, etc.) into a single RGBA texture, dramatically reducing texture memory usage and draw calls in your projects.
Key Features
🎯 Universal Pipeline Support
- Full support for Built-in Render Pipeline
- Optimized shaders for Universal Render Pipeline (URP)
- Professional shaders for High Definition Render Pipeline (HDRP)
- Automatic shader detection and material setup
🚀 Advanced Packing Features
- Pack up to 4 textures into RGBA channels
- Real-time preview with zoom and pan controls
- Drag & drop texture assignment
- Multi-texture selection and auto-assignment
- Smart texture naming detection (automatically assigns metallic, roughness, AO, height)
🎨 Professional Channel Control
- Extract from any source channel (R, G, B, A, or Grayscale)
- Value remapping (min/max control)
- Channel inversion
- Per-channel settings with animated UI
🛠️ Workflow Optimization
- One-click presets for common packing formats:Standard PBR (Metallic/Smoothness/AO/Height)
Unity HDRP (Metallic/AO/Detail/Smoothness)
Unity URP (Metallic/Occlusion/Detail/Smoothness)
Unreal Engine (AO/Roughness/Metallic)
- Batch processing support
- Automatic texture import settings configuration
📊 Output Control
- Adjustable texture resolution (128x128 to 8192x8192)
- Multiple texture formats (PNG, EXR)
- Compression quality settings
- Mipmap generation
- Filter mode and wrap mode control
- sRGB/Linear color space support
🎭 Demo & Testing Tools
- Create demo scene with sample objects
- Generate test textures (gradients, noise, radial)
- Example material creator for each pipeline
- Interactive camera controls in demo scene
