I am trying to create a smokey "afterburner" on a spaceship. How do you control the density direction to simulate different environments? In this case, I want to simulate space (zero density?), where "smoke/fire" looking effects should not go upward, but should disperse evenly in the emitter direction.
You can see in the picture when the emitter changes direction, the smoke does not change direction as you would expect in space.
- Turning down density on both smoke emitter (flow) and box (domain)
- Smoke still goes straight up
- Using particle system
- The particles move in the desired direction, but the smoke always floats up
