Jet of fire

Hi all. Hope, u will help me -
I wanted to create a jet of fire for fire traps, but i faced to some problems.

  1. When I placed a jet on scene, it started blow strange fireballs, but when a player stays next to a trap ( in game mode ) or camera takes a nessesary place ( in viewport while editing a lvl ), jet ‘blows’ normally. How to fix these fireballs, cuz i need that these jets must be visible despite camera or player’s placement.
