You could do it with a custom material on the spheres surrounding the lights in conjunction with attenuating shadows (which will be fixed as soon as I have real Internet access and can commit the changes). Just have the new materials attenuateShadows call do nothing (but defined so it overrides the default implementation).

It's easy to add a bunch of spheres to the scene at light positions (something similar is done for camera path control points, it's all application code). I'm not sure if you could add spheres enclosing the lights, and then prevent the spheres from casting shadows across the whole scene.

I could give you pointers on where to start looking around, but I don't have time to implement that feature.

Once you have a working prototype we can evaluate your solution before it goes main line.

Hi,
I'd like to be able to see the location of lights (probably represented by spheres) in scenes in Manta. Is there any reason why this shouldn't be added to the system?
     Thanks,
