ofxAruco and ofLights

have been playing with the excellent ofxAruco addon/wrapper by @arturo and I haven’t been able to figure out the lights yet. Using the example provided, if I turn off the transparency the dummy box is rendered with a flat white. I tried moving the lights here and there but with little effect. At some point I was getting the light.draw() to render it in what I thought was the right location, but it was obvious the light was coming from another source.

Anybody has encountered this issue?

Anybody know how to introduce lights to ofxAruco “scenes”?
