Hey @kylenox ,
I have reviewed the above file,
and found there is a particle system on the smoke particle as well as the smoke emitter,
There should only be a particle system on the Emitter.
Have a look to see you haven’t done the same.
If so, remove the particle system on the smoke particle.
Delete all bakes, check the particle settings on the emitter,
play the animation all the way through,
you should now see 161 frames in memory under cache of the particle system.
now bake the particle system,
And render.
You should now be able to launch without exploding your rocket.
Hope this helps!
