Streamline Your Game Assets with Our PBR Channel Packer

In real-time rendering and game development, memory optimization is everything. Our PBR Channel Packer is a vital tool for technical artists and 3D developers looking to consolidate their texture maps. By combining separate grayscale textures—such as Ambient Occlusion, Roughness, and Metallic (ORM/RMA)—into the individual Red, Green, and Blue channels of a single image, you drastically reduce texture draw calls and memory overhead.

Optimized for Unreal Engine, Unity, and Custom Pipelines

Instead of loading three distinct 4K textures into your engine's memory, channel packing allows you to load just one. This RGB packing process is the industry standard for major game engines like Unreal Engine and Unity. Our intuitive online channel packer lets you drag and drop your grayscale maps, assign them to your desired color channel, and export a highly optimized, game-ready texture in seconds. Reduce your project's file size, improve frame rates, and maintain a seamless 3D optimization workflow.
