Ill have to try it as a card again. I converted my tiff to a extruded plane and deleted the lower vertices, than mirrored it for a kinda square lighting bolt. These hard faces may be playing with the luminosity rays maybe? I dunno.
Also I did make a light source populator thats on NWDA. Just online. I should be able to pack it as a executable with the portable Chrome browser with PHP built-in though. It can do spheroid and square pops as well as some tricks like setting min and max sizes, intensities, light limits, and colour, as well as variation percentages of colours for each instance, and of course light source checkbook settings.
