Channel Packer Pro

Channel Packer Pro can pack and swizzle up to four different textures into a single texture, fast and effortlessly with the help of GPU acceleration. Simply set each channel using a value slider or use any channel from a source image or generated image. Additionally invert channels with a single toggle for each channel or postprocess the output texture before export.

Designed with artists in mind with its intuitive layout, simple controls and preview windows that update as soon as you make a change. The preview windows work in a similar way as the built in texture preview window in Unity. But with the added ability to preview each channel in greyscale and preview selected channels in any combination giving you more control while staying consistent with the Unity editor.

Streamlines and automates finding, packing, processing and exporting textures in a non destructive workflow with presets, packing group generators and channel packer projects that can be saved in your Unity projects. Save your projects to quickly make changes or continue later, Save presets for frequently used combinations and conversions, save and use packing groups to set up your project once and let channel packer do the rest.

Channel packer projects, presets and packing group generators can be packaged for reuse in other Unity projects to save you from having to set them up with every new Unity project.

Comes with default postprocessors and image generators but you can script your own.
