A Simple Diffuse Substance Painter is not a competitor to Adobe Substance 3D Painter, but a focused, accessible alternative for artists who want direct color control without PBR complexity. By stripping away roughness, metallic, and normal maps, you gain:
Next step suggestion: Implement the tool as a Blender add‑on or a small Godot editor plugin, using GPU-based painting for real‑time feedback.

To "prepare a piece" using the SimpleDiffuse generator in Substance Painter, you can follow this streamlined workflow to create high-quality, stylized textures in under 10 minutes.
SimpleDiffuse is a specialized generator (often used by artists from Nhance School
) designed to speed up the texturing process by automating shadows, ambient occlusion (AO), and color gradients. 1. Project Setup Import Mesh : Load your 3D model into Substance 3D Painter Bake Mesh Maps
: Ensure you bake your mesh maps (especially Curvature and Ambient Occlusion) as SimpleDiffuse relies on these to calculate its effects. Add Channels Texture Set Settings , ensure you have a Base Color
channel. If you plan to use procedural filters like HBAO, also add an 2. Applying SimpleDiffuse Create a Fill Layer : Add a new fill layer to your layer stack. Add the Generator : Right-click the layer (or its mask) and select Add Generator SimpleDiffuse from the list. Configure Base Settings Base Color : Set the primary tone of your material. Shadow/AO Color
: Adjust the shadow color (often a darker, cooler tone) and its spread to create immediate volume. Curvature Opacity : Tweak this to highlight edges or add wear. 3. Adding Variation and Detail Top/Bottom Gradients
: Use the built-in gradient controls to add color shifts (e.g., warmer on top, cooler/darker on bottom), which is highly effective for organic models like characters. Layer Masking Black Mask to your SimpleDiffuse layer and use the Polygon Fill
tool (UV or Object mode) to restrict the material to specific parts of your model. Hand-Painting : Create a simple diffuse substance painter

This guide covers the "SimpleDiffuse" generator—a specific tool designed for streamlined stylized texturing in Substance Painter—as well as the general process of creating and exporting diffuse (Base Color) maps for non-PBR or simplified workflows. 1. Understanding SimpleDiffuse
The SimpleDiffuse generator is a specialized tool for Substance Painter that helps artists create stylized textures by focusing on three core components: Base Color: The foundational hue of your object.
Shadow Color & Spread: Controls the intensity and reach of multiplied shadow colors.
AO (Ambient Occlusion) Color & Spread: Adds soft depth to crevices and corners. 2. Setting Up Your Project
Before applying diffuse textures, ensure your project is properly configured to generate the necessary data for your shaders.
Baking Mesh Maps: Go to the Bake Mesh Maps window. Baking "Ambient Occlusion" and "Curvature" is essential, as these maps drive the smart effects in SimpleDiffuse.
Channel Selection: In your Texture Set Settings, ensure the Base Color channel is active. If you are aiming for a purely diffuse look, you may disable Metallic and Roughness to save on resources, though Roughness is often key for realistic highlights. 3. Applying the SimpleDiffuse Generator
Once your maps are baked, follow these steps to use the generator: Create a Fill Layer: Add a new Fill Layer to your stack.
Add a Black Mask: Right-click the layer and select Add Black Mask. A Simple Diffuse Substance Painter is not a
Apply the Generator: Right-click the mask and select Add Generator. Click the "Generator" slot and choose the SimpleDiffuse asset from your shelf. Adjust Parameters:
Shadow Spread: Increase this to "flood" the darker areas of your mesh.
AO Intensity: Use this to define the "inner" shadows of your model. 4. Creating a Custom "Simple" Smart Material
If you want to reuse your diffuse settings across multiple objects, you can create a Smart Material:
Group Your Layers: Select your Fill Layers and press Ctrl+G to put them in a folder. Rename: Name the folder (e.g., "Stylized_Base").
Save as Smart Material: Right-click the folder and select Create Smart Material. It will now appear in your shelf for future use. 5. Exporting Your Diffuse Maps
To get your textures out of Substance Painter and into engines like Unity or Blender: Open Export Window: Go to File > Export Textures.
Output Template: Choose a template like PBR Metallic Roughness or Unity Universal Render Pipeline (URP).
Locate Base Color: Ensure the Base Color (sometimes called Diffuse or Albedo) is checked.
Export: Click Export. You can then drag these files directly into your 3D software's shader slots. Next step suggestion: Implement the tool as a
Do not use the "PBR Metallic Roughness" default fill layer as your diffuse. Instead, create a new Fill Layer. Rename it Base_Diffuse. In the properties panel, disable the Height, Roughness, and Metallic channels. Only enable Base Color.
Set the Base Color to your primary hue. For the shield, that might be a desaturated brown (#5A3A22). This is your simple anchor.
| Component | Description | |-----------|-------------| | Layer Stack | Non-destructive layers (blend modes: Normal, Multiply, Screen) | | Brush Engine | Simple round brush + alpha stamps (hard/soft edges, opacity, flow) | | Mask System | Paint on layer masks (black hides, white reveals) | | Projection | 2D viewport + auto-UV island detection (per-triangle painting) | | Export | Single diffuse color map (optional: + alpha for opacity) |
This tool is designed for:
Diffuse Map = The base color of a surface, without lighting information (no shading, just flat color + hand-painted variation).
To create a simple diffuse substance painter in Substance Painter, follow these steps:
Painting and Customizing:
Enhancing with Layers and Effects:
Exporting and Implementation:
A simple diffuse substance painter is a versatile and powerful tool for creating high-quality textures and materials. By understanding how it works and how to create one, you can quickly and easily add realistic materials to your 3D models.
Code Example (Python)
import substance_painter
# Create a new project
project = substance_painter.Project(width=2048, height=2048)
# Create a new material
material = project.create_material("Diffuse")
# Create a new texture
texture = project.create_texture("Diffuse", width=2048, height=2048)
# Paint the diffuse texture
# ...
# Configure the material
material.diffuse = texture
# Export the material
material.export("wood_chair.sbsar")
