Rocket Smoke

[DNorman]

I would probabley go for a particle system rather than a smoke sim (maybe due to my old hardware!),

I find particles much faster and more controlable, it is also very easy to have the emmitter folow a path and leave a trail as the particles will “linger” leaving a trail. There are many parameters to control their initial velocity, lifetime size etc etc.

I used particles for my traction engine smoke:

I have finally added the differential effect to the wheels. At first I tried to use the rotation of the main drive control bones as a factor for my rotation driver, but that only worked going into the turn, coming out it would revers the desired effect! In the end I placed two new bones perpendicular to the chassis bone (for the back wheels) and the front wheel direction bone (for the front wheels). The z rotation of those bone does work. Now it will react to all the turns automatically along t…
