Sutoms, Put a bulb with brightness at 1% just outside the box in front of the object (uncheck CAST SHADOWS box) and activate the lens flare.. The low setting will not interfere with the lighting of the scene and it will show the lens flare. Do not drop the brightness to 0% as this just turns off the light, and consequently the lens flare. As far as I know, this is the only way to accomplish the effect. Light will pass through transparent objects, but the effects will not. Check a couple of threads back and you will see something about the refraction settings that seemed to be buggy. Same basic thing... Ken
