   How to detect that a character has come into contact with 3ds Max particles?
  Currently, I am working on combat between a monster and the player character.  The monster has an attack animation which blows out green particles of gas.  These particles are part of the attack animation which is created in 3ds max by the artist.How do I know when the player character and the 3ds max particles come into contact with one another?Currently, the player character is in "God" mode. He does not get hurt even when those gas particles are blown onto his face.   
  You know the position of all of the particles, because you render them. You also know the position of the player, and you can determine his extents when you load the model. Then you just need to check if the particle position is inside the player.
