How do I make textures for 3D models in Photoshop?

To make textures for 3D models in Photoshop, start with the model's UV layout so you know where each surface sits on the 2D canvas. Paint or place material details on the correct UV islands, use layers for color, dirt, decals, seams, and masks, then export maps such as Base Color, Roughness, Opacity, or Emissive depending on your pipeline. Photoshop is useful for manual 2D work, but creating a full PBR material by hand can be slow because normal, height, roughness, and metallic maps need separate attention. A faster workflow is to generate finished maps in TextureFast and use Photoshop only when you deliberately want hand-drawn labels, decals, or custom 2D graphics.
