Question

Hi all,
I wanted to try some experiments with the MeshDataTool but I’m having trouble assigning a mesh for it to process.

I have a simple scene setup with a mesh object.

Then I’m exporting the arraymesh to the editor.

    [Export] public Node3D meshNode;
    [Export] public ArrayMesh arrayMesh; 
    
    public void _Ready()
    {
        var mdt = new MeshDataTool();
        mdt.CreateFromSurface(arrayMesh, 0);

I’m just not sure how to assign the arraymesh in the editor so I can supply it to the MeshDataTool.

Could someone point me in the right direction here?
Thanks!

Pete
