Spline Brush - Turn Splines into Brush Strokes

Spline Brush is a Geometry Nodes-powered tool that can convert curves to cards based on surface normals and splines on a mesh surface, allowing you to paint brush strokes or decals on a 3D model by simply drawing curves.

Documentation: Spline Brush Docs
Tutorial: YouTube

And the tool contains modifiers and shaders with explanatory tooltips for each parameter.

Works with Blender 4.1+ and supports:

• Drawing splines on surfaces with automatic alignment by surface normals.
• Editing curve radius, tilt globaly and per curve.
• Packing and storing of UV maps with support for custom UV layouts.
• Creating your own stroke\decal atlases or trim sheets.
• Baking generated UV maps and textures.
• Guided scattering that generates a lot of small cards based on density parameters.
• Curve extension, normal offset. Masking these parameters in the texture-painting mode.
• Shrinkwrap.
• Camera culing.
• Camera space projection
• And many more...
