Reply To: Particles only emitting on one side of my plane?

Hey @brandonwamboldt ,

Using a plane as an emitter, you will only have particles emitted from one side.

The plane emitter has only one face, which makes it simpler.

Every face of every object has a positive (blue) side and a negative (red) side, aka external and internal on an object such as a cube.

The normal velocity in the particle settings will be a positive number to emit from the positive side (blue) and a negative number from the negative side (red).

For the rocket launch you want this normal velocity set as -1.

Make sure your particle system is on your Smoke Emitter object only, I see similar issues with the smoke, often the particle system is also on the Smoke Particle object.

Hope this helps!
