A Stone Path or Road Generator in Blender Geometry Nodes

This Blender 3.3 project file places multiple stones along a curve to form a road or path. Each stone has variable height and dimensions leading to a natural, cobblestone effect. The amount of detail in the surface is adjustable for a tradeoff between resolution and vertex count. A number of other controls are provided to control the number of rows and stones per row, trim the egde of path for a more rectangular appearance, surface roughness, and height variation. Also included is a path converted to a mesh, UV-unwrapped, and with a free stone texture applied to show what final effects are possible.
