GreebleFX is a tool that automates the creation of panels and greebles on 3D models. It utilizes a non-destructive workflow to generate randomized surface details, streamlining the process of modeling spaceships, cityscapes, and mechanical structures. The tool includes two primary generation modes: a Basic mode for standard panels and an Advanced mode for intricate greebles and nurnies. Users can adjust various parameters, including panel count, island distribution, nurnie factor, height, and density, to customize the generated patterns directly from the interface.
