Вот краткое пособие по составляющим эффекта самолетного дыма
Цитата:
ClassInfo]
ClassName TParticlesSystemParams
[General]
MatName Cannonsmoke.mat
Color0 0.64 0.66 0.68 1.0 // Start color (R B G A) 0 = Black 0.65 0.67 0.69 0.11
Color1 0.61 0.61 0.55 0.0 // End color (R B G A) 0.66 0.61 0.55 0.01
nParticles 300 // # of smoke particles 288
FinishTime -1.0 // How fast to draw 1st particle? , -1=draw continuously /Time before smoke starts to dissapear, begins to fade.
MaxR 1.0 // Max repeats? 1.0
PhiN 1.0 // Angular speed 1.0
PsiN 1.0 // Angular speed 1.0
LiveTime 6.0 // How long each smoke from conception to completion 4.0 How long the smoke will continue to come from the wings,
the start begins to fade.
EmitFrq 72.0 // Frequency emission, higher = more smoke
particles 48
EmitVelocity 0.5 4.0 // Min / Max speed of the emission 0.5 4.0
EmitTheta 90.0 0.0 // Min / Max angle of the emission 85 95
GasResist 0.01 // Resistance to expansion, lower = faster dispersal 0.05
VertAccel -0.6 // How fast to move up down vertically -0.6 if you want the smoke to rise "hence to gain altitude"
Wind 1.0 // wind is a random speed which moves particles
1.0 How Much Wind there will be when the smoke leaves the wings
Size 3.0 8.0 // Size of particles, start & ending size 2.0 8.0 The size the smoke will be
Rnd 0.30
================================================== ================================================== ====================================
my defs
nParticles 4096 The number of particles assigned to a cycle
FinishTime -1.0
MaxR 0.0
PhiN 0.0
PsiN 0.0
LiveTime 4 length of the cycle
TranspTransitionTime 0.0f
EmitFrq 120 speed at which particles assigned is used up
SegmentLen 106
MaxObjectVelocity 150 I think this indicated how fast the smoke travels in the direction of the object that emmits it
EmitVelocity 2.0 5.0
EmitTheta 0.2 5.0
GasResist 0.05 How gradually it disperses, lower value fades away better, highr value stops abruptly. max value is 2/0 I think
VertAccel -0.0 this, and the wind setting, will make the smoke move after emmision. Vert accel seems to be how fats it rises..or falls
Wind 1.2
Size 1.0 2.0 Size at source and size when it starts dispersing
See this has two values. In this case the second is a bigger value, so the smoke will expand before it disperses, try this the other way round for fuel leaks or such.
Rnd 0.1
