ImportMesh wireframe mode

[Dad72]

Hello,

 

How can we change the material of a model that was being loaded which has already a material.
I would like to replace the existing material by another material in wireframe mode.

Thank You

Just call mesh.material = myNewMaterial

[Dad72]

It does not work.

I fact:

BABYLON.SceneLoader.ImportMesh(Name, CheminModeles, Fichier, scene, function (newMeshes, particleSystems, skeletons){                        if(newMeshes[0]) {                                                        modele = newMeshes[0];                                  var myNewMaterial = new BABYLON.StandardMaterial("wireframe", scene);                            myNewMaterial.wireframe = true;                            modele.material = myNewMaterial;                            scene.activeCamera.attachControl(container);                }});

The model has always its textures by default to display.

It should work with your code. Is there anything in the javascript console ? Can you share more of your code please ?

[Dad72]

In the console i have constantly:

 

UnknownError  (5 error babylon.js (ligne 20))

...terialsIds .push(subMatId);parseMaterialById(subMatId,parseData,scene,rootURL);}...

 

 

 

More code

function init(CheminModeles, Fichier, Name) {                    var engine = new BABYLON.Engine(container, true);                scene = new BABYLON.Scene(engine);                                    BABYLON.SceneLoader.ImportMesh(Name, CheminModeles, Fichier, scene, function (newMeshes, particleSystems, skeletons)                {                                if(newMeshes[0]) {                                                        modele = newMeshes[0];                                                    modele.rotation.y = 0;                            modele.position = new BABYLON.Vector3(0, 0, 0);                            var myNewMaterial = new BABYLON.StandardMaterial("wireframe", scene);                                                        myNewMaterial.wireframe = true;                                                        modele.material = myNewMaterial;                                                        scene.activeCamera.attachControl(container);                        }                                                                                    });                                camera = new BABYLON.ArcRotateCamera("Camera", 1.52, 1.52, 150, new BABYLON.Vector3(0, 35, 0), scene);                                light = new BABYLON.HemisphericLight("Hemi0", new BABYLON.Vector3(0, 1, 0), scene);                light.diffuse = new BABYLON.Color3(1, 1, 1);                light.specular = new BABYLON.Color3(1, 1, 1);                light.groundColor = new BABYLON.Color3(0, 0, 0);                                engine.runRenderLoop(function ()                {                        scene.render();                                    });               }

This code should work correctly. I just tested it quickly and everything is correct for me.

 

The function Importmesh import the mesh called "Name" and all its submeshes. Are you sure the material is updated on the correct mesh and not one of its children ? You can display the updated mesh name to be sure (console.log(modele.id)) in your callback function.

[Dad72]

In console.log (modele.id)

 

return:

a67642f6-d8e2-405c-ac73-deab1df21da5

 

 

I used the models 'Dude' of samples project and I rename the file name by him.Babylon

for the 'name' of the function init(), i retrieves the name of the file.

 

I have not understood this:

Are you sure the material is updated on the correct mesh and not one of its children ?

newMeshes[0] is a dummy object. It is the parent of the visual mesh. Just change to newMeshes[1]

[Dad72]

Thank You Deltakosh, it works.

 

By contrast I have always these errors in the console that has no effect, but is on each load models.

 

UnknownError  (5 error babylon.js (ligne 20))

...terialsIds .push(subMatId);parseMaterialById(subMatId,parseData,scene,rootURL);}...

I knew it !!

 

Gj guys !

[Dad72]

And for the error line 20 in Babylon.js what is this error?

[GameMonetize]

Do you have a site where we can see the error occuring?

[Dad72]

No, I work locally on this project.

But I will see if i can not make a small version of this part of the program and put it on my server.

Do you have a site where we can see the error occuring?

 

No error online ???

 

I note that online, the error does not appear.

Therefore, the error is when one is in local and not online.

[GameMonetize]

This is due to CORS (cross origin security). babylon.js (and almost all 3D engine) must be used online to get rid of this security issue

[Dad72]

OK, I did not know this. Thank you.
