In this tutorial I show how to merge different textures sets into one image by using the alpha channel inside Substance Painter to export the images with transparency and merging them in Photoshop into a single image, per texture map. This comes very handy for game assets using multiple materials. Also quick tip: if you are exporting textures for Unreal Engine, make sure to check off the sRGB option in your ORM texture so you can use it as Linear Color in your material. Hope this helps :)
