Blender export obj 不导出双面对象。如何以双面模式渲染对象。我试过这个没有成功:
var loader = new THREE.OBJMTLLoader();
loader.load('models/test.obj');
loader.addEventListener( 'load', function ( event ) {
objects = event.content;
objects.position.set(0,5,0);
objects.scale.set(1.5,1.5,1.5);
objects.mesh.doubleSided = true;
scene.add(objects);
});
