why don't work alpha channel and Transparency when loding obj file

[lingkernyurk.]

I am a beginer of babylon.js.

I was going to load obj file using babylon.objfileloader, but did't work alpha channel and transparency in loading obj.file.

The code I worked is follow

var loader = new BABYLON.AssetsManager(scene);
BABYLON.OBJFileLoader.OPTIMIZE_WITH_UV = true;
var mesh;
mesh = loader.addMeshTask("bane", "", "Assets/Chicken Coop/", id + ".obj");

obj file works well in assimpView, but don't work in babylon.js

Here is result by babylon.js

 

I believe you to help me.

best regards.

Could be the way the file was exported. Can you show the associated mtl file?

hi,

maybe you have a similar issue I had in this thread.

I'm pretty sure the materials.hasAlpha flag isn't set to true...

Hi javalang

Thanks your reply.

I did work as you said, but it don't work well.

Send my code.

           mesh = loader.addMeshTask("bane", "", "Assets/"+ type +"/", id + ".obj");
            mesh.onSuccess = function (task) {
                allMesh = task.loadedMeshes;
            for(i=0; i<task.loadedMeshes.length;i++)
                {
                           allMesh.material.diffuseTexture.hasAlpha = true;
                }

I believe you can help me.!

 Waiting for your reply.

I wasn't able to load your file into the sandbox, I think there is some mismatch in the obj-file.

What I did: importing into blender and exporting it to test.babylon with "Texture location"-option is set to "inline" for enbedding all textures. No special code required to render the file.

Hint for loading objects in general: first make sure the import into http://sandbox.babylonjs.com/ is correct, after then your programmatically import will also be fine

in the attachment you can find my converted .babylon file.

Hope this helps.
