(WebGL Error) DrawElements: bound vertex attribute buffers..

[aphex-]

I get this Error if I try to inport a jsonmodel. (FireFox 11, WebGL.Verbose = true) WebGL: DrawElements: bound vertex attribute buffers do not have sufficient size for given indices from the bound element array (Three.js:281) Any ideas? :)

Edit: I do only use the geometry of this file and later aply a material.

Could you also share the relevant code where you're loading this?

I found the problem while I reduced my code to the relevant lines. I used the same instance of a THREE.JSONLoader for more files synchronously. This is obviously not the best idea. Thank you for respond again.

OK.. same problem again (THREE.js r47).

        var jsonLoader = new THREE.JSONLoader(true);
        jsonLoader.load("Models/palette.json", function(geo){
            var mesh = new THREE.Mesh( geo, new THREE.MeshFaceMaterial());
            scene.add(mesh);
        } );

Using THREE.MeshFaceMaterial() or any other Material with a texure does not work. Materials without textures are working. The file "palette.png" is in the same directory like the json-file (256x256px). Any ideas? :)

You don't have texture coordinates in your model. You need to create real UVs in Blender, not just use its procedurally generated coordinates.

And this worked... thank you :)
