Update 22-09-28:

• Fixed an issue causing crashes in UE5;

With this utility you can:

• Edit packed textures (textures with different informations on each RGB Channel, e.g. roughness, metallic, masks, etc);
• Unpack packed textures into grayscale textures, outputing each channel into individual ones;
• Package textures from grayscale ones (injecting grayscale images into any of the RGB channels);
• Swap channels (e.g. moving green channel to red channel, etc);
• Select one of the channels as the "output data", meaning that texture's resolution and path will be used to output the final content;
• Browse to the channels or the output content with a single click on the tool;

IMPORTANT: Remember to Enable the "Editor Utility Scripting" plugin, and to run it, right-click on "UBP_RGBRepacker" and choose "Run Editor Utility Widget".
