: Because it uses a simple layer setup, you can quickly swap colors or adjust shadow depth without starting over. How to Use It
If you want to follow an older tutorial that mentions a "Diffuse" channel and you don't see it, don't worry. In modern Substance Painter, the Base Color channel is your diffuse map.
In the realm of 3D modeling and texturing, Substance Painter has emerged as a leading tool for creating high-quality, realistic materials and textures. One of its fundamental features is the ability to paint and customize materials directly onto 3D models. A crucial aspect of this process is understanding and utilizing the "Simple Diffuse" feature within Substance Painter. This guide aims to provide an in-depth look at what Simple Diffuse is, its applications, and how to effectively use it in your texturing workflow.
Once your simple diffuse setup looks good in the viewport, it is time to export the textures for your engine of choice (Unity, Unreal Engine, Blender, etc.). Navigate to . Select your output directory. simple diffuse substance painter
Avoid painting directly on the default layer. Instead, use for better control.
Use the Dirt generator with a dark brown color, masked by the Ambient Occlusion map, to add grunge to corners.
Create another Fill Layer. Set the color to a bright, light tint of your base color. Disable all channels except . Add a Black Mask and add a Generator . : Because it uses a simple layer setup,
Substance Painter’s generators are great for speeding up simple diffuse creation.
Start with 2048 × 2048 for painting, and you can reduce this later. Setting Up Your Channels
Why? Because modern game engines and renderers (like Unity, Unreal, or Marmoset) calculate those dynamically. If you paint shadows into your diffuse map, the engine will double them up, resulting in a muddy, "dirty window" effect. In the realm of 3D modeling and texturing,
Under the list, locate Roughness , Metallic , and Height .
In a standard PBR (Physically Based Rendering) workflow, "Diffuse" is referred to as . It represents the raw color of your object without any lighting or surface information like glossiness or metalness.
