Paintexture

Paintexture is a 3D texture painting app for Windows. Load a model, paint straight onto it, and watch the texture update in the 2D view at the same time.

FEATURES

- Paint on the model in 3D and on the texture in 2D, side by side

- Layers and folders: blend modes, opacity, masks, clipping, drag and drop

- Brushes: brush, pixel brush, airbrush, spray, smudge and eraser, with pressure support

- Make your own brushes: size, spacing, flow, hardness, scatter, jitter, custom tips and curves

- Depth channel with live relief on the model, and a normal map you can tune and export

- Selections, transform (free, distort, warp), mirror painting and filters

- Pen tablet support (Windows Ink or WinTab) with pressure

- Textures up to 8K, many undo steps, and seam padding for clean UV borders

- Multiple UV sets and materials per model

- Model formats: GLB, GLTF, FBX, OBJ, DAE, STL, PLY (and .blend if Blender is installed)

- Export: PNG, PSD with all layers, and normal maps

- Projects save everything (model, layers and settings) in one .ptex file

- Background autosave that never pauses your painting

- Custom themes, movable panels and editable shortcuts

REQUIREMENTS

- Windows 10 or 11, 64-bit

- A graphics card with WebGL2 (most cards from 2014 on). 4 GB of video memory recommended for 4K textures and up

- Microsoft Edge WebView2 Runtime (already included in Windows 11; the installer links to the free download if it is missing)

NOTES

- Early Access: it works and is used daily, but it is still growing. Bug reports and ideas are very welcome in the comments.

- Windows may show a "Windows protected your PC" warning because the app is not signed yet. Click "More info" then "Run anyway".
