3D Collider Utility 2 - Merge and Combine v2.0.1|3D Collider Utility 2 - Merge and Combine v2.0.1

 The 3D Collider Utility 2 - Merge and Combine v2.0.1 is a game resource pack that allows developers to create a merged collider of the entire hierarchy with a single click. It supports both runtime and editor-based collider merging and works with multiple collider types including box, sphere, capsule, wheel, terrain, and mesh colliders. For terrain colliders, it creates a simplified version using a vertex decimation algorithm while preserving edge details. The tool includes new optimizations such as vertex merging and hidden face removal. It features a simple editor window and a straightforward API with two main functions: ColliderUtility.CreateCollider(gameObject, settings, disableColliders) and ColliderUtility.CreateFilter(gameObject, settings, createGameObject). Note that the tool does not clean up geometry, and combined meshes may include internal structures if meshes overlap. The asset utilizes MeshSimplifier and MICcomplexHull under the MIT license, allowing unrestricted commercial use.
