//| PSYS_PART_BOUNCE_MASK //Bounce on object's z-axis
| PSYS_PART_WIND_MASK //Particles are moved by wind
| PSYS_PART_INTERP_COLOR_MASK //Colors fade from start to end
| PSYS_PART_INTERP_SCALE_MASK //Scale fades from beginning to end
| PSYS_PART_FOLLOW_SRC_MASK //Particles follow the emitter
| PSYS_PART_FOLLOW_VELOCITY_MASK//Particles are created at the velocity of the emitter
//| PSYS_PART_TARGET_POS_MASK //Particles follow the target
| PSYS_PART_EMISSIVE_MASK //Particles are self-lit (glow)
//| PSYS_PART_TARGET_LINEAR_MASK//Undocumented--Sends particles in straight line?

//PSYS_SRC_TARGET_KEY , NULL_KEY,//The particles will head towards the specified key
//Select one of the following for a pattern:
//PSYS_SRC_PATTERN_DROP Particles start at emitter with no velocity
//PSYS_SRC_PATTERN_EXPLODE Particles explode from the emitter
//PSYS_SRC_PATTERN_ANGLE Particles are emitted in a 2-D angle
//PSYS_SRC_PATTERN_ANGLE_CONE Particles are emitted in a 3-D cone
//PSYS_SRC_PATTERN_ANGLE_CONE_EMPTY Particles are emitted everywhere except for a 3-D cone
