Some of FBX models appears as full black

Hello!
I am creating the 3D Viewer for some model formats. In my scene, some of the FBX models appear black.
The model example is attached.

Mojo_Idle.zip (3.5 MB)

As far as I understand the problem is only with MeshPhongMaterial.

Do you mind sharing the model with all of its textures? When drag’n’drop the model into the three.js editor, you can see a whole set of textures FBXLoader tries to load:

If i try to load the shared model (without textures) in another viewer I see this

You can achieve the same result by iterating through the loaded model and set the map property of the materials to null. Do this in your onLoad() callback:

object.traverse( function ( child ) {

	if ( child.isMesh ) {

		child.material.map = null;

	}

} );

The problem is that the “empty” textures result in a black color which makes the vertex colors not visible anymore.

I understand what you mean, but I don’t understand why in the same causes another 3D Viewer (like https://3dviewer.net/) shows this:

and my shows this:

For this model also some materials appear as black, but all textures were loaded

Sorry, in that case, the problem is with a lighting

I’ve just replaced the model in webgl_loader_fbx with Mojo_Idle.fbx, removed the animation related code and set the map properties to null. Maybe you can use the same approach to easier find out what’s missing in your app.

Yeah, if I set material.map to null I see the result like in another 3D Viewer.

Thank you. Sorry for my stupid)
