Quick Start Guide

Zero to Packed Texture in 10 seconds.

1. Installation

1. Copy the TextureChannelPacker folder into your project's Plugins directory.
2. Restart Unreal Engine.

2. Step-by-Step Workflow

Step 1: Open the Tool

Go to Tools > Texture Channel Packer.

Step 2: Drag & Drop Inputs

Drag your textures directly from the Content Browser into the slots.

• Tip: Standard ORM layout is Red = Ambient Occlusion, Green = Roughness, Blue = Metallic.

Step 3: Verify & Generate

1. Notice that the Output File Name is automatically generated (Smart Naming).
2. Set the Width and Height for your output resolution (they can differ for non-square textures).

   Note: Resolutions above 8192px will show a memory warning dialog before processing.

3. Toggle Invert on any channel if you need to flip values (e.g., Roughness → Smoothness).
4. Click the Folder Icon if you need to change the save location.
5. Click Generate Texture. If an asset with the same name exists, a confirmation dialog will appear.

Pro Tips

• Empty R, G, B slots are automatically filled with Black (0). Alpha defaults to White (255).
• No need to resize textures beforehand; the tool handles it automatically.
• For ORM maps, leave the Compression setting on Masks.
• Use the Invert checkbox to flip values per-channel — no need to edit source textures.
• Width and Height can be set independently for non-square output textures.
