3DSmax Exporters

[renjianfeng]

Hi ，When I use the Babylon file, which is exported by the 3dsmax exporter, some of the time, my model will have all sorts of weird problems.

I list some problems, because of these features in 3 ds Max normal performance, Only in babylonjs will appear problem, Maybe I, informs it incorrectly, Only at some point will there be a problem, what is straightforward.

1.Some time, when I add parent to the mesh as a whole, the loaded model returns to the center of the scene.

  var groundMaterial = new BABYLON.StandardMaterial("groundMaterial", scene);
        groundMaterial.alpha = 0;

        var ground = BABYLON.Mesh.CreateGround("ground", 512, 512, 32, scene, false);
        ground.material = groundMaterial;

        for (var i = 0; i < scene.meshes.length; i++) {
            scene.meshes[i].position.y += 13;
            if (i < scene.meshes.length - 1) {
                scene.meshes[i].parent = ground;
            }
        }

        ground.scaling = new BABYLON.Vector3(0.1, 0.1, 0.1)

2.The position of the mesh is incorrect

For example, the position of the door frame

I need to know which default parameters need to be set in 3dsmax to avoid these problems，Please forgive me for my poor English. I have used some automatic translation tools.

Why do you need parenting meshes to the ground ?

I'm not quite sure, but I think this code

            scene.meshes[i].position.y += 13;

will reset all meshes Y position to 13, so of course all meshes will be moved, positioning their center pivot to Y=13 ; isn't it ?

 

[edit ] no i get it, it add 13 to the value, so as to be up to the ground i suppose [/edit]

Do you have clean your meshes in 3dsmax before exporting ? like reset transform & scale & xform ? It maybe be a solution. I have a maxscript to one-click this, save before using it ; when xform are applied, if your mesh is broken,it will explode and no ctrl Z is possible

I need to do a whole operation on all the mesh, like this:

Ground. Scaling = new BABYLON. Vector3 (0.1, 0.1, 0.1)

Rotation, scaling, position and so on

That's why I got the meshes to the ground.

Do you have a better way to do this?

Your model is not just one mesh but several.

You will need to load a scene (with Load() or Append()) and not a mesh (with  ImportMesh()).

Then list each object in your scene to apply a scaling on them.
