Scribble Gen is a collection of Geometry Nodes presets designed to generate meshes, volumes, and particle effects using curve drawing workflows. Users can draw splines in Edit Mode to create structures like brick walls, barbed wire, hanging cables, chains, and cobwebs. The toolset also includes generators for scattering objects, instancing on curves, and emitting particles for effects like fire and dripping fluids. Each preset exposes customizable parameters in the modifier tab, including options for scene collision, curve radius scaling, and mesh realization.
