THREE.JS Exporting JSON models from blender (including textures)

sparkyspider picture sparkyspider · Mar 6, 2013 · Viewed 24.4k times · Source

I'm using the mrdoob Blender Export Plugin (io_mesh_threejs) to Export to Three JS, but the exported .js or .dae objects do not contain any reference to the texture map files. Is there a special way I need to export the object? Alternatively, is there a special way I need to apply the map to the object in Blender 2.65 in order for the exporter to include it. Lastly, if there is not a way, can I manually add the texture in the JS file?

Code To Load JSON Object

var object;
var loader = new THREE.JSONLoader();          

loader.load( "./quirk_logo.js", function(geometry, materials) {
     var material = new THREE.MeshFaceMaterial(materials);
     object = new THREE.Mesh(geometry, materials);

     object.scale.set(1, 1, 1);
     scene.add(object)
     render();
});

I think you can first export your model to .obj from your Blender and then follow the rest part of this tutorial to get your right .json model.
