Hmm i just thought of a new way of cutting down modelers time :D , how about for the smoke the spies throw down tiny balls that release smoke .. similar to the ones you see batman use :D!.
...and make the smoke purple, like the one in Naruto.
Hear that modellers? A sphere instead of a cylinder! That will save you the time it takes to set a height.
lmao, it's not much more work lol
