Features

 

  • Enables resizing particle with distance and current angle between emitter and camera; e.g., a lens flare shown only when you look into the engine bell.
  • Enables changing the particle renderMode (http://docs.unity3d.com/Documentatio...enderMode.html)
  • Enables rescaling the emitter in the .cfg, permitting resizing of both model and effect.
  • Adds a "grow" variable whereby particles can grow with time
  • Adds a curve for emission, energy, speed, grow, size and emitters scale & offset with variation of atmo density and vessel Mach speed.
  • Particles collide with terrain.
  • Exhaust persists even when the engine is destroyed.
  • Compatible with the stock MODEL_MULTI_PARTICLE. Basic config uses the same args
  • Does not call the kraken when you change scene (stock does that on Flight => Spaceport on certain condition )
  • Limits number of active particle to twenty-thousand (soon configurable) and usually stays well-below

 

Future

 

  • Ship-centric emitters
  • Surface effects; e.g., dust, water.

 

I know the rules, not pict not click but you'll have to wait for Nothke to publish his engine config for the picts :)

So how does it works ? First you need to define an effect. Look into the "HotRockets!" thread for a working example with stock KSP.

You just have to change the MODEL_MULTI_PARTICLE into a MODEL_MULTI_PARTICLE_PERSIST

Here is a minimal config with only the required info

 

name = flamethrust

modelName = MP_Nazari/FX/flamestandard

transformName = thrustTransform

 

Here is the same config with all the default value shown : 

modelName = MP_Nazari/FX/flamestandard
transformName = thrustTransform
shaderFileName =
renderMode = Billboard
collide = False
collideRatio = 0
localRotation = 0,0,0
localPosition = 0,0,0
offsetDirection = 0,0,1
fixedScale = 1
sizeClamp = 50
initialDensity = 0.6
physical = False
stickiness = 0.9
dragCoefficient = 0.1
timeModulo = 10
singleEmitTimer = 0
randomInitalVelocityOffsetMaxRadius = 0
angle = 1
distance = 1
emission
{
	power = 1
	density = 1
	mach = 1

	time = 1
}

{
	power = 1
	density = 1
	mach = 1
	parttemp = 1
	externaltemp = 1
	time = 1
}

{
	power = 0
	density = 0
	mach = 0
	parttemp = 0
	externaltemp = 0
	time = 0
}
force
{
	power = 0
	density = 0
	mach = 0
	parttemp = 0
	externaltemp = 0
	time = 0
}

{
	power = 0
	density = 0
	mach = 0
	parttemp = 0
	externaltemp = 0
	time = 0
}

{
	power = 0
	density = 0
	mach = 0
	parttemp = 0
	externaltemp = 0
	time = 0
}
logGrowScale
{
	power = 1
	density = 1
	mach = 1
	parttemp = 1
	externaltemp = 1
	time = 1
}
lengthScale
{
	power = 1
	density = 1
	mach = 1
	parttemp = 1
	externaltemp = 1
	time = 1
}
velocityScale
{
	power = 1
	density = 1
	mach = 1
	parttemp = 1
	externaltemp = 1
	time = 1
}

 

So now let's explain all those.

First we have 2 kind of config parameters :

- fixed parameter : all the xxx = yyy from modelName to angle

- curve : the entries with a subsection like emission or energy

The Fixed Parameters

modelName : point to the model of your effect. it's the same as the stock FX so you'll have to find stock tutorial on how to build those in unity.

transformName : part transform where your effect is attached

shaderFileName : point to a compiled shader text file to replace the default shader of your model. Not testes all that much

renderMode : set the particule renderMode, one of Billboard/HorizontalBillboard/SortedBillboard/Stretch/VerticalBillboard. See unity doc http://docs.unity3d.com/ScriptReference/ParticleRenderMode.html

localRotation : rotation of the effect. For when you did not align correctly in unity or want to point an other way

localPosition : move the effect away from the transform its attached to.

offsetDirection : direction of movement when offset is used, see offset curve.

fixedScale : fixed scale of the effect. For when you want to rescale to effect or the part

sizeClamp : maximum size of the particle.

collide : does the particle collide with stuff. False / True

collideRatio : change how the particle collide. Test in game to see the effect. Set to a value between 0 and 1

stickiness : how is the particle slowed on collision

physical : simulate the buoyancy of the particle/gas

initialDensity : density of the particle/gas at its starting size

dragCoefficient : atmo drag on the particle/gas

timeModulo : used with the time input (see bellow with the curve)

singleEmitTimer : when different than 0 change the behaviour of single emit event ( like flameout ) and replace them with an emission of x seconds.

randomInitalVelocityOffsetMaxRadius : let me copy Egg comment on the value

The initial velocity of the particles will be offset by a random amount lying in a disk perpendicular to the mean initial velocity whose radius is randomOffsetMaxRadius. This is similar to Unity's 'Random Velocity' Setting, except it will sample the offset from a (normal) disk rather than from a cube. Units (SI): m/s.

The Simple Curves

angle and distance distance are curve with only 1 input. They are used to resize particle with the camera distance and angle with the transform. They were added for flares effects. Since they are curve you need to add the line more than once to set them up.

For exemple here is a config that show the particles if the angle of the camera with the transform is lower than 45° :

 

  
angle = 0.0 1.0 // at 0° do not resize
angle = 45.0 1.0  // at 45° stil don't resize
angle = 50.0 0.0 // from 45° to 50° and beyond resize to 0. ( with 47.5° being half size)

 

The Multiple Input Curves

Those change different parameter of the effect in relation to multiple input curve. Those inputs curves are :

- power : the power sent to the effect. 0 to 1. For engines it's related to the throttle (set or current, it change with the engine config)

- density : atmo density.

- mach : current speed in mach. For now mach speed is calculated for AIR.

- parttemp : the part temperature

- externaltemp : the external temperature

- time : time in second modulo "timeModulo". So you get a repeating sequence between 0 and timeModulo.

Curve are divided in additive en multiplicative curve. The additive add the result of the inputs and the multiplicative multiply them.

emission : multiplicative. Change the number of particle emited per second

  

emission // Modulate emission from mach and density curve. You can add other section for size, energy, speed, grow, offset and scale
{
	mach = 0.0 0.0
	mach = 0.8 0.0 // don't display until mach .8
	mach = 1.0 3.0

	density = 1.0 0.0
	density = 0.4 0.0 // don't display over .4 atmo
	density = 0.3 1.0
	density = 0.002 1.0
	density = 0.001 0.0 // and stop under .001
}

 

energy : multiplicative. Change the energy (life in s) of each particle

speed : multiplicative. Change the particle speed

grow : additive. Change how the particle grow with time with a exponential functions. 1 is 100% per second

 

SS_grow.png

 

scale : multiplicative. Rescale the emitter

size : multiplicative. Rescale the particles

offset : additive. Move the emitter away from the transform in "offsetDirection"

force : additive. Change the power of the force applied to the particles each frame

logGrow : additive. Change how the particle grow with time with a logarithmic functions

 

SS_log.png

 

linGrow : additive. Change how the particle grow with time linearly

 

SS_lin.png

 

logGrowScale : multiplicative. Change the log function base

lengthScale : multiplicative. How much are the particles stretched in their direction of motion.

velocityScale : multiplicative. How much are the particles strectched depending on "how fast they move". Use this to make particles get longer as their speed increases.

randConeEmit: additive default value 0 (no cone emission), similar to

randomInitalVelocityOffsetMaxRadius, but a little less random effect

appearance in-game. Forces a mirrored emission to ensure symmetric

plume appearance.

xyForce: multiplicative default value 1, multiplicatively damps or grows horizontal

(perpendicular to exhaust velocity) speed.

zForce: multiplicative default value 1 multiplicatively damps or grows vertical

(parallel to exhaust velocity) speed.

Two questions:

Can the color of a flame be altered via plugin, or would it have to be through texture/modeling? Ideally what I want to do is have a set of colors representing various substances and temperatures to interpolate between.

Second, can particles be made to spawn at an offset from the origin in order to create a cylindrical (or rectangular) sheet?

1. Color, not yet.

2. You can create a spawn shape like a circle, ellipse, box, plane, point and a few more shapes from the particle exporter options. You can create offset in two ways, one is to create an offset by moving the system in Unity, then puting it under a parent gameobject, and another way is to add a "localOffset = 0,0,0" line, or "offset = 0.0 0.0" if you need to make it moveable, although it works in just one dimension (Y).

Spawn shape is more what I'm after than offsetting the effect as a whole, in which case what I'd need would be a hoop I guess. (Equivalent to offsetting each individual particle a fixed distance at a random angle in the plane.)

Nothke found a bug related to part unloading ( think SRB falling down ). I uploaded a new version that should fix that but their trail will vanish until I find a proper way to handle this case.

Mother of God....does this mod add that to all engines or do I have to edit them myself?

SmokeScreen doesn't add anything visually. It's a plugin to help creation of new particle systems including a lot of fixes from the stock exporter. What's in the screens is a particle mod that I am developing right now.

Man, this is locking gorgeous, but i will wait until it have an proper set of config to all rockets .

Great Job! ;)

Hey Nothke, will you post or set of config files for us?

sarbian: Great plugin! One remark however:

I'm not sure whether it's too late to change the identifiers (there shouldn't be too many compatibility problems right now), but I think 'persistant' should be replaced by 'persistent' (unless you intended to name the classes in French). I'll report it as a bug on GitHub.

nothke: These screenshots look great!
