How would I remove the long streaks at the end of the flame of a pyro sim? I want there to be a harsh cut off between the body of the flame and the long streaks that extend from it, and this making my whole simulation more box like than long if that makes sense. I have been messing around with the flame height and remap heat cool field curve, along with cooling rate but I can't seem to get the effect that I want to.
Attached is a snapshot of my pyro playblast along with the reference that I am trying to match it too. The red outline is what I consider the "body" of the flame and the green ones the "streaks" coming out of it which I want to remove. Please offer your suggestions on how to solve this problem.
