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
