Trash Gen is a geometry node setup and asset pack designed to scatter refuse across 3D surfaces. The generator automatically aligns the scattered items to the target object and allows users to restrict spawning to specific faces. It includes controls for adjusting the overall density and selecting specific types of trash, such as paper cups, crumpled papers, chip bags, cigarettes, trash bags, leaves, rocks, and pebbles. Additionally, the tool supports custom weight painting to manually mask and dictate exactly where the trash is distributed on the mesh.
