How do i remove a mesh from memory that was created by the combineMesh script?

For performance reasons i often combine a whole lot of meshes together... and it happens often and it changes often. It works great, but my problem now is i realize that each time i do it .. it adds to the total vram used. It says so in unity and it will crash my android app after about 30 combines... So....

The question now is how do i remove a mesh from memory that was created by the combineMesh script?

I have tried using destroyImmediate() on the gameobject that houses the mesh filter... i have even went and did something like this on the mesh in the mesh filter.....

"if (currentNode.GetComponent<MeshFilter>())
{
Mesh mesh = currentNode.GetComponent <MeshFilter>().mesh;
DestroyImmediate(mesh);
}

DestroyImmediate(currentNode);

"

So what am i missing? Why do i continue to add to the VRAM usage until i run out?

 

Just realize it also adds to the VBO Total ....

My only assumption is that im creating meshes that arent being removed from memory when im done with them.... Am I wrong? What do i do?

 

I have tried using...
"DestroyImmediate(mesh, true);"
and
" DestroyImmediate(mesh, false);"

neither make any difference...

 

well i managed a workaround which is kind of an annoying workaround, but for now i am using "Resources.UnloadUnusedAssets()"

And that removes stuff from the memory, but still I would love to know why the mesh doesnt get destroyed when i try... anyone know?

 

The below code is the answer I have been looking for. instead of <MeshFilter>().mesh; im using <MeshFilter>().sharedMesh;

"if (currentNode.GetComponent<MeshFilter>())
{
Mesh mesh = currentNode.GetComponent <MeshFilter>().sharedMesh;
DestroyImmediate(mesh, tue);
}

DestroyImmediate(currentNode);

"

 

Thank you, my good man!

 

Great!

 

Thanks hero!

 

I know this is an older thread, just want to say thank you, as I was building up a lot of memory from unused meshes and this thread saved the day!

 

Thanks!)

 

DestroyImmediate(mesh, true), is this destroys asset permenantly from project ?

 

Thanks!)))))))))))))))

 

Due to DestroyImmediate usage are not recommended I use this:

Code (CSharp):

1. meshFilter.sharedMesh.Clear();
2. GameObject.Destroy(meshFilter.sharedMesh);
3. GameObject.Destroy(<GameObjectWithMeshFilter>);

 

Thanks hero!hero!hero!

 

I’m curious. I’m not familiar with the combined mesh script. But should this way be done for any mesh?

 

Kudos!
Thanks to actual Profilers in Unity, the mesh count can be tracked in the Profiler.
But the issue still remains in Unity 2021 (I'm using 2021.2.13f1). A modified version of the code of @Shaman7 with reinstantiating the GameObject even when the Mesh is only replaced with another one saves me 30MByte/s of Garbage.
