Thanx...

BTW. very nice & good Video Tutorial at DvGarage.com...

I also found a bit more... got very curious...

"Smoke & Mirrors - Heat Wave" by Alex Lindsay
https://www.3dgate.com/news_and_opini...4alindsay.html
it looks a bit like it... he is also using red and green colors for the particles...

here is also one which look interesting... but it is unfortunately for lightwave... "Afterburn Tutorial"... -->
https://www.dynamic-realities.com/sup...afterburn.html

I don't know if this tutorial also might be useful... e.g. if the speed of jetflow is going up or down... "Using Particle Speed" by Alex Alvarez... -->
https://www.thegnomonworkshop.com/tut...eed_color.html

btw. is the "6 story Parking garage" a movie part or a part of an model in Maya?
