Problem with multimaterial export from blender

[mandim]

Hello,

I'm having an issue when trying to import a blender model (i.e. .babylon). I have created a simple bottle in blender with multimaterials (3 colors) and export it to .babylon. Here is the snippet code:

var bottleMeshTask = assetsManager.addMeshTask("BottleTask", "Bottle", "assets/Bottle/", "bottle.babylon");
                bottleMeshTask.onSuccess = function (task) {
                    console.log(task);
                    bottle = BABYLON.Mesh.MergeMeshes(task.loadedMeshes, true, true, null);
                    bottle.position.z = -150;
                    bottle.position.y = 0;
                    bottle.position.x = 10;
                    bottle.rotation.z = Math.PI / 2.0;
                    bottle.scaling = new BABYLON.Vector3(0.3, 0.3, 0.3);
                    console.log(bottle);
                    
                };
                bottleMeshTask.onError = function (task, message, ex) {
                    console.log(message, ex);
                }

                assetsManager.load();

 

The problem is that when I insert the asset using the addMeshTask(...) it only shows the top first material.

Any ideas?

bottle.babylon

bottle.blend

Seems like the multimaterial is defined ("multiMaterials":[{"name":"bottle.Multimaterial#0","id":"bottle.Multimaterial#0","materials":["bottle.White","bottle.Blue","bottle.Red"]}]) but it is missing a few parameters. 

What material is applied to the mesh?

Actually only the white material is being applied.

I checked the .babylon in the sandbox, and it loads fine from there.  I see no problem in what Blender produces.

I know that in sandbox its loading fine. That's why I created this topic. Is it possible to load the .babylon in the playground and how?

[JCPalmer]

It is possible.  You do have to post the .babylon on an addressable area of the web to get.  You then use the code you have with the right url.  Usually you have to make minor changes to fit within a createScene function.

This may be due to you merging the meshes. Try without merging the meshes and see if this solves your problem.

Thanks for the notice. This resolved the issue.

Many thanks...
