How to make a rocket?

I have recently started to use ue4 after attending camp and started thinking about making a rocket, so I did. I made 2 meshes in blender for the rocket and started watching some YouTube videos. I found that when trying to make an emitter that would pool smoke and exhaust I was unable to make the smoke pool and it would either go through the ground, shoot off into the abyss, or stay exactly where it landed. I used GPU sprites for it and cant find any way to make it pool up. I saw a video of someone doing what I imagine it could look like ( Unreal Engine - Rocket Launch test - YouTube ).I was also wondering if it would be possible to make a 2 stage rocket. I tried doing it but cant get the collision to go around the model correctly and it instead just goes right over the hole for the upper-stage engine. Would there be a way to make parachutes deploy while either stage is falling, or make a set flight path? I would like to make the rocket in a blueprint, but not the emitter. Thanks in advance for any help you can give.

To make a set flight path in Unreal, you might want to put it into a Sequence. You could even animate the whole flight in your content creation tool, use Root Motion and import that into Unreal as a Skeletal Mesh with a Root Bone.

I couldn’t get Cascade to do anything with particle collisions other than make them stop instantly or disappear, either.
Maybe have to make them all separate Actors with their own collision (can all use the same Blueprint though)
