Problem with babylon.csg, dispose method and material property

[Anonymous]

var b1=new BABYLON.Mesh.CreateBox("box1",3.0,scene);

var b11=new BABYLON.StandardMaterial("b11",scene);

b11.diffuseColor=new BABYLON.Color3(1,1,0);
b1.material=b11;

i have created one box and applied material property and i have also subtracted another box from b1 box using babylon.csg like

var b2=new BABYLON.Mesh.CreateBox("box2",1.0,scene);

var b1CSG=BABYLON.CSG.FromMesh(b1);
    var b2CSG=BABYLON.CSG.FromMesh(b2);
    
    subCSG=b1CSG.subtract(b2CSG);
    
    b1.dispose();
    b2.dispose();
    
    subCSG.toMesh("csg",new BABYLON.StandardMaterial("mat",scene),scene);

After this, hole is created inside box1 but the material property i have given is not applied to the box1.

How can i apply this material property to box1 after dispose method?

Thanks...!!

Hi Anonymous (who is that masked stranger) and welcome to the forum. Do you know about the playground ? Putting your code into the playground is the best way to get help from the many responsive people on this forum.

NOTE do not use new when creating a box mesh. In your line  subCSG.toMesh("csg",new BABYLON.StandardMaterial("mat",scene),scene);  the new standard material you created has not been given any properties use a material you have previously set see PG below.

Here is a working playground http://www.babylonjs-playground.com/#GSRTH#1
