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.
in the inspector they are not 
decomment : mesh.dispose()
does it work for you?
it doesn’t on my end 
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:
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.
r.
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
Lucky us, it isn’t me coding the world 
Humanity might still stand a chance after all 
They backup often, I hope so
Thank you SO much for looking into this and solving it @roland !
You are very welcome!
