Collider Tools is a Blender addon to create physics colliders for games and real-time applications. The addon offers a lot of tools for creating the most common collider types like Box, Sphere, Convex, Convex (cylindrical), Auto Convex (Windows only), and Mesh quickly and easily within Blender. These colliders can then be imported to engines like UE, Unity, and others.
The addon offers big flexibility and controllability by using the selection, both in Object and Edit-mode, as well as offering settings like global or local space generation. Further, the addon supports the generation based on both the original mesh (pre-modifier stack) and the evaluated mesh (post-modifier stack). Collider Tools offers functionality for organizing the colliders, showing, hiding, and selecting them and tools to automatically generate multiple convex shapes to represent complex meshes (convex decomposition)
