Applying material not working with .glb/.gltf but works with .obj


Recommended Posts

Hello

I am unable to apply material to objects loaded in .gltf/.glb format but am able to do so for objects loaded in .obj formal.

I have attached chair_gltf.png, chair_obj.png and relevant code below.

I would like to create a demonstration in the babylon playground but cant since I dont know how to add assets to the playground.

Questions

1) Can someone help me figure out how to apply materials to models loaded via gltf?

2) How does one add static assets to babylon playground?

function addObject(scene, model){
  var scale = model.scale;
  var pos = function(t) {
      t.loadedMeshes.forEach(function(m) {
        console.log(m.material)
        m.scaling = new BABYLON.Vector3(scale,scale,scale);
        let materialSphere1 = new BABYLON.StandardMaterial("texture1", scene);
        materialSphere1.alpha = 0.5;
        materialSphere1.diffuseColor = new BABYLON.Color3(1.0, 0.2, 0.7);
        m.material = materialSphere1;
        console.log(m.material)
      });
  };
  var loader = new BABYLON.AssetsManager(scene);
  let file_dir = dirname(model.gltf_url).substring(1) + '/'
  let file_name = basename(model.gltf_url)

  var object = loader.addMeshTask(model.title, "", file_dir, file_name);
  object.onSuccess = pos
  loader.load();
}

@Luaacro I have this playground to demonstrate the issue. The chair on the left is glb and the chair on right is obj. The relevant code follows

    // create loader
    var loader = new BABYLON.AssetsManager(scene);
    var glbTask = loader.addMeshTask("batman", "", "https://dl.dropboxusercontent.com/u/28136236/models/chair/", "chair.glb");
    var objTask = loader.addMeshTask("batman", "", "https://dl.dropboxusercontent.com/u/28136236/models/chair/", "chair.obj");

    // function that takes a mesh and applies pink material
    function applyMaterialToMesh(mesh){
        var materialSphere1 = new BABYLON.StandardMaterial("texture1", scene);
        materialSphere1.diffuseColor = new BABYLON.Color3(1.0, 0.2, 0.7);
        mesh.material = materialSphere1;
    }

    // applies pink material and move mesh one to left
    objTask.onSuccess = function (task) {
        task.loadedMeshes[0].position.x += 1
        applyMaterialToMesh(task.loadedMeshes[0])
    }

    // applies material but does not move to left
    glbTask.onSuccess = function (task) {
        applyMaterialToMesh(task.loadedMeshes[0])
    }

I hope this suffices. The code in my project is slightly convoluted.
