I add a SpotLight with SpotLightHelper to three box use tb.Object3D({obj:spotLight}),and setCoords(coords),but the SpotLightHelper `s coordinates looks like at the (0,0) even I set any coords, here is the code can be use to test.

@huohuli008 Same problem I get part of the answer to the SpotLightHelper question. 1.I find SpotLightHelper is wrong display but the actually the SpotLight run properly under threebox. 2.The SpotLightHelper appers to be wrong on calculating the matrix inside it`s hard to be corrected from outside threebox. 3.What I recommend is that you should build a alternative helper thing just like the pic below

It`s not work as good as SpotLightHelper but it helps me to deal with the SpotLight problem. Hope to give you some help.
