I think what you are asking is 'Can Bryce Generate Storms, Lightning, Volcanic Eruptions' in the same manner that Lightwave 3D does through the Digital Particle Stream it calls Hypervoxels and the answer is "NO", But I agree with the Bryster that many people have created, from scratch, some Very Awesome looking storm sequences. And for that matter Neither can Vue generate them, but you can create it in much the same manner as you would in Bryce.

I would rather be Politically Incorrect,
Then have Politically Correct-Incorrectness!!!
