In this video we are going through the process of how to pack different maps(Emission, Roughness and Metallic) into a single image file in different channels(Red, Green and Blue) to then be able to use those channels as separate masks in our engine of choice.
We are using Photoshop and Unreal Engine 5 in this example, but the philosophy should apply to all other similar software.
