The Marble Run Master Kit provides a comprehensive set of 3D components for constructing custom marble run structures. The collection includes 209 total assets, derived from 49 core elements such as rails, curves, spirals, slopes, crossings, angles, catchers, and blocks. The assets are provided in FBX format, enabling compatibility with Blender.

Each core element is supplied in up to five distinct resolution variations to accommodate different use cases. These variations range from a low-poly version optimized for fast rigid body physics simulations, to medium and high-resolution iterations featuring varying degrees of surface wear and beveled edges. Additionally, ultra-resolution versions include extensive sculpted detail targeted at close-up rendering workflows.
