PBRgen turns a text prompt or image into a full PBR material ready for any 3D software.
Work through the steps left to right: generate a base texture, edit it, create the material maps, tweak each map, then export.
Every material you create is saved to your library automatically.
Type a prompt describing the surface you want and click Generate.
Use Presets to load example prompts.
Use Enhance to improve your prompt with AI.
Use Surprise me for a random prompt.
Drag an image into the prompt area to generate a prompt from it automatically.
Results appear as thumbnails. Click one to select it. Use the arrow keys to navigate.
Optional
Prompt style: applies a style modifier to steer the visual style.
Input colors: seeds the generation with specific colors.
Guide map: provides a spatial reference image to control composition.
Model and resolution can be set before generating.
Edit repaints the selected texture with AI while keeping its overall structure.
Choose a preset or write your own edit prompt.
Each edit creates a new version. Click thumbnails to compare.
Use Add original prompt to append your generation prompt to the edit prompt.

Adjust seam size to control how wide the inpainted region is.
Choose a resolution and click Create material from texture.
Adjust each PBR map using a layer stack.
Click a map tab at the top to select it: COL, ROUGH, NRM, DISP, MTL, REFL.
Click Add to add a layer. Layers process from top to bottom.
Drag a layer header to reorder it.
Layer types
Sources (Map, Color, Noise, Math): add or blend content into the channel.
Effects (Blur, Levels, Brightness, Contrast, etc.): adjust everything below.
Press V or click 2D in the viewport to see the active map in real time while editing.
Set a material name. Maps are saved as [name]_COL.png, [name]_NRM.png, etc.

Your materials are stored in My materials.
Click a material to open it.
Right-click a material for options: rename, delete, or move to a folder.
Drag materials into folders to stay organized.
Examples contains sample materials to explore different styles.
The 3D viewport shows a shaderball preview of your material.
Press V or use the 3D/2D button to switch views.
In 2D mode you can zoom and pan the texture.
In the Tweak step, 2D mode shows the active map updating in real time.
