Feedback for the artist is very important when creating effects. He has to be able to see them in-game. This process is very painful for the poor artist. He has to leave his comfortable creative environment and cross the corridor to where "The Programmers" are working. These two species speak a different language, so communication is sometimes hard. Artists tend to forget that implementing particles in the game is not easy. Standing behind the programmer, asking "Still not finished????" every minute, doesn't help either.​
