Eric this is a great extension! It reminds me a one for 3DS Max called LumaObject. Except that LumaObject doesn't have to make to make the object glow. This means that it can be used to make a fake radiosity effect without the taxing the CPU. Is it possible that you could make this extension with the option of not making the object glow, but just emit the light? Or is there a work around with AG as it is now to achieve this effect?
