How to see collision shapes on an object in babylon.js "MeshImpostor doesn't work"

Physics, The ball goes through the terrain

As I wrote before, OimoJS does not support the MeshImpostor. It uses a box instead. So either use a BoxImpostor, or switch to a physics engine supporting the correct impostor-type, like CannonJS or AmmoJS: Use a Physics Engine - Babylon.js Documentation Edit: Check this PG: Babylon.js Playground Lines 21 - 23. Try OimoJS, and you’ll see the mesh isn’t used. Instead it uses the boundingBox of the model. CannonJS and AmmoJS both use the geometry. Can be used with heightmap terrain as well: http…

CannonJS’ MeshImpostor only works with spheres. If you need other Impostor types I would choose AmmoJS instead.
