The TOON Stuff still has a ways to go- I think E-On has just finally begun to address the Python Issues- More will happen there as more advanced users start working with the Toon Materials. I've done some R&D stuff- but I don't know PYTHON...

Here's a more Volumetric looking STORM CLOUD- actually two that were cloned from one. NOT my BEST Lightning Prop- I have 11 more- but not quite ready in VOB format.

The Storm Cloud is made up of a Nimbo-Cumulus ANVIL shape
(flat bottom) and I threw in a couple of WISPY Clouds for a VAPOR-LIKE Vortex and some HEAVY RAIN washing down. These from the Flight Sim set. STILL SO MUCH MORE can be done with these cloud shapes. I've barely scratched the surface of the many beautiful cloud shapes that can be made from them...
