```auto
for (let i = 0; i < scene.meshes.length; i++) {
            let mesh = scene.meshes[i];
            if (mesh.name.endsWith("_merged")) {
                scene.meshes.splice(i, 1);
                // mesh.dispose()
            }
        }

```

why does mesh.dispose() throw an error?

First: It is not a good idea to remove an item within a loop over the items. You should go from the last item backwards to index 0: for (let i=scene.meshes.length-1; i\>=0; i–) …

Second: mesh.dispose() returns this error. I suppose you have to remove the Hawok body first before removing the mesh because they are connected together.

I would like to answer your question with the word from scene of Romeo and Juliet on the balcony (act 2, scene 2):

no.

Hi!

Here is a working PG:

> **[Babylon.js Playground](https://playground.babylonjs.com/#Z8HTUN%23417)**
>
> Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes

Errors in your PG:  
`redMat.diffuseColor = new BABYLON.Color3.Yellow();` delete `new`  
the same at line 79

Delete this:  
`scene.meshes.splice(i, 1);`

and this at line 41:  
`scene.disablePhysicsEngine()`

If you disable Havok, it will destroy the world (you know what I mean, don’t reveal this to Kim Jong 😃😃 😃 ) so you can’t safely dispose the mesh.

You can disable it after the mesh has been disposed.

Added async to your functions to init the Havok engine as the doc says.

🖖

LoL, good one. I won’t mention that I tried for 20min disposing of the body before disposing of the mesh 🤐, thinking the same as @CodingCrusader…though it’s hard to dispose of something that no longer exists, isn’t it ? 🤭 😅

Yep 😉 Imagine if we live in a simulation and a coder makes a mistake an disables the physics engine and it will destroy the world… We are fucked 😃
