I'd like to have smoke which changes colour with speed and/or collision. Is this possible? I've been tinkering for days and can't quite get what I want. In the smoke shader there's only the option of fluid channel, but I can't seem to change based on particle age, or speed, collision etc. Is there any solution to this issue? Idealy I need the smoke to change through three of four different colours as the animation progresses.
I'm a Lightwave user by the way.
Thank you in advance of any help :-)
