Identifying and contoling mesh

[Mpman]

Hi there, i am a Bab3D junior.

I was wondering how do i identify and control an imported mesh i.e. (newMeshes[0].position.x=100;)

My mesh is newMeshes[0] other meshes [1] [2] etc.

myMesh = newMeshes[0];

myMesh.position=''; //Babylon

myMesh.css("display","none"); //jQuery object.style.opacity

myMesh.whatever...

 

Thanks!

@Mpman hy there and welcome to Bjs, you can use var mesh = scene.getMeshById("put the name of the mesh you need here);

you can use the debugLayer to find the submeshes in your imported mesh, you can find the name of the mesh that you want there.

The debugLayer is really a great tool for this

var mesh = scene.getMeshById("put the name of the mesh you need here);

Hi Mpman,

If the imported meshes are from the SceneLoader then you can change their properties after loading:

BABYLON.SceneLoader.ImportMesh("", "/dir/", "file.obj", scene, function (loadedMeshes) {
  loadedMeshes.forEach(function(loadedMesh) {
    console.log(`loaded ${loadedMesh.name}`, loadedMesh)
  }
});

If you want to hide a mesh instead of using css, try to set it's visibility property to 0.  So, in the code above you could do:

if (loadedMesh.name === 'hideme' ) {
  loadedMesh.visibility = 0
}

If you share the file you are importing and where you are stuck we can be more helpful.

@MpmanAnd you can't use css with the imported mesh...you're working with webgl

Thanks a lot for your responses!
