CrossSection is a Unity tool that lets you create real-time cutting, slicing, and cross-section visualizations for 3D models. It works with static and skinned meshes, generating clean cross-section surfaces with customizable colors, materials, outlines, and effects. Ideal for architectural previews, scientific demos, destruction systems, and stylized gameplay mechanics. The tool supports URP, HDRP, and Built-in pipelines, includes shader-based and mesh-based modes, and offers high performance even on mobile. Easy to integrate and highly customizable, CrossSection helps you reveal interiors, slice objects interactively, or showcase layered structures with minimal setup.
