USD Prop Randomizer
Artists often reuse models such as grass, flowers, and bowls to build a scene. When every copy has the same scale and rotation, the scene can look repetitive. Adjusting each object manually takes time. USD Prop Randomizer is a PySide6 tool for layout and set-dressing artists working with USD scenes in Maya. It helps artists find repeated props by name and add size and rotation variation without adjusting each object individually.
