	To compute how many particles are emitted per second, divide Count by Time. This leads to an important observation: in order to make particles live X times longer, you have to also increase Count in X times, if you want to keep the same emitting speed.		To compute how many particles are emitted per second, divide Count by Time. This leads to an important observation: in order to make particles live X times longer, you have to also increase Count in X times, if you want to keep the same emitting speed.

			Note that if you design particle system to apply to surface emitter (with "particle deform" material), then Count is specified per 64 x 64 area of emitting surface. So the larger is emitting surface in this case, the more particles will be rendered at every moment. This small adjustment is very useful e.g. for rain, because it allows you to create emitting surface of arbitrary size, and it will always have same particle density.

	'''Orientation''' has major effect on how particles are rendered. If you want just to render particle aligned to the viewer, use View orientation. This is typical value for smoke, fire, fountains, and many other effects. If you want particles to always face up, then set orientation to Z.

Now, for easiest editing of particles, load up an existing particle, such as the leaf one in the example, modify it and then use "save as". I will explain a bit more further down.

	Firstly, and most importantly, we have '''~~material~~'''. This is the path to your material; not the image file but the material for your custom leaf. So for example you can see the example above has textures/particles/tdm_leaves_01. If you know the name of your material (for example textures/particles/green_leaves) then you can type that in there and press enter and it will find it by itself showing the changes in the render view.		To see the changes you are making, center your camera in the render view on the tree and press {{key\|F7}} and {{key\|F6}}. {{key\|F7}} rebuilds everything and {{key\|F6}} enables animations. Leave it in render view and move the particle editor to the side so you can see the render view (to watch the changes you are making as you make them).

			Firstly, and most importantly, we have '''Material'''. This is the path to your material; not the image file but the material for your custom leaf.

If you know the name of your material (for example textures/particles/green_leaves) then you can type that in there and press enter and it will find it by itself showing the changes in the render view.

	~~Now that~~ you can ~~see your custom material we~~ can ~~continue on~~ to the ~~size~~ of the ~~leaves etc~~.		Other things which combine with material are '''Color''' and '''FadeColor'''. The material you use will be modulated/multiplied by the color value specified. So if you have a white particle texture, you can set color to "1.0 0.3 0.3" to make all particles green. Or you can set color to "0.05 0.05 0.05" to make particles much more transparent. The FadeColor should usually be fully zero, since it specifies the color of a fully "faded-away" particle. The particle can also change the color dynamically using fading settings. If you want particles to gradually disappear during the second half of their lifetime, set '''Fade Out''' to "0.5". If you want the particles to gradually appear from nowhere during the first 20% of their lifetime, set '''Face In''' to "0.2".

	'''~~cycles~~''' determines how many times the particle effect will play. Zero value means "infinite number of times".		'''Cycles''' determines how many times the particle effect will play. Zero value means "infinite number of times".
	In general, a particle system repeats itself prescribed number of times, and every such time is called a "cycle".		In general, a particle system repeats itself prescribed number of times, and every such time is called a "cycle".

This is large enough so that player does not notice randomly disappearing/appearing particles.

	'''~~bunching~~''' this determines how much the particles tend to bunch together: 0.0 means they all come out at first instant, 1.0 means that they are emitted evenly over cycle time, 0.4 means that all particles come out in the first 40% time part of the cycle.

	'''~~count~~''' controls how many particles there are (at any moment), so basically the example shown has 32 particles in total. Obviously the more you have, the more dense the effect is, and the more performance it costs. This is a slider so slide it around as necessary. Alternatively you can input a value into the box and then press apply down the bottom right.

Obviously the more you have, the more dense the effect is, and the more performance it costs. This is a slider so slide it around as necessary. Alternatively you can input a value into the box and then press apply down the bottom right.

			To compute how many particles are emitted per second, divide Count by Time. This leads to an important observation: in order to make particles live X times longer, you have to also increase Count in X times, if you want to keep the same emitting speed.

			'''Orientation''' has major effect on how particles are rendered. If you want just to render particle aligned to the viewer, use View orientation. This is typical value for smoke, fire, fountains, and many other effects. If you want particles to always face up, then set orientation to Z.

	~~To see the changes~~ you ~~are making~~, ~~center your camera~~ in the ~~render view on the tree and press {{key\|F7}} and {{key\|F6}}~~. ~~{{key\|F7}} rebuilds everything and {{key\|F6}} enables animations~~. ~~Leave it in render view~~ and ~~move~~ the particle ~~editor~~ to ~~the side so~~ you ~~can see the render view~~ (to ~~watch~~ the ~~changes you are making as you~~ make ~~them)~~.		The last really useful orientation type is "Aimed", which allows you to stretch every particle along its movement direction, drawing a trail behind particle. The Time number is the duration in seconds of the trail. Better set this to low values like "0.1" first, then try to increase/decrease and tune how long you want the trails to be. This trail feature is useful to turn an ordinary fire particle into a fireball, or an ordinary puddle particle into a long rain droplet.
			The Trails number should always be zero, unless you want to see curved trails. If you set Trails to K > 0 (integer), then every particle will be rendered as (K+1) quads, so every trail will consist of K+1 segments. Note that amount of geometry sent to GPU also increases in (K+1) times, so setting big values will decrease performance. On the other hand, bigger values may be necessary to make curves trails smoother.

	'''Distribution''' ~~This is where things get a little more annoying.~~ You'll notice 3 check dots - rect, cylinder, and sphere. ~~Realistically you'd want~~ to ~~use sphere, but for some reason~~ the ~~algorithm for distribution~~ in the ~~sphere (at least for the leaves) does not work correctly and~~ you ~~get several particles occupying~~ the ~~same spot, which results in z-fighting and generally looks really bad~~. ~~Now, the rectangle distribution works perfect; particles are properly distributed and there is no z-fighting, but it's a rectangular shape, but~~ can ~~look ok~~ if ~~not too many~~ particles ~~are used. Another alternative is the cylinder distribution. Cylinder distribution works well but annoyingly enough the particles get distributed only on the walls of the~~ cylinder, ~~which means a hole in the middle, so you need to adjust the particle size and cylinder size so that there is no hole in~~ the ~~middle~~.		'''Distribution''' You'll notice 3 check dots - rect, cylinder, and sphere, describing the shape of emitting zone.
			The values to the right are the size values in doom units, so change that to roughly be the size you want the emitting zone to cover.
			The nonzero ring value can be set if you want to emit particles from cylinder or sphere surface, not from the whole volume.

	~~The values~~ to the ~~right are the size values in doom units, so change~~ that ~~to roughly be the size you want the leaves to cover~~. ~~If you selected cylindrical distribution,~~ don't ~~bother adding a ring value as it just makes it larger~~ in ~~diameter~~, so leave it at 0.		Note that if you intend to apply particle system to a surface (instead of particle model), then the emitting position is already chosen randomly on that surface.
			You don't need distribution in this case, and can leave it as "rect 0 0 0".

	The ~~offset~~ is ~~the~~ offset from the center of the particle entity. Try keeping the leaves centered on the particle emitter, as Doom 3's light rendering system calculates whether or not to light the particles by checking whether the particle emitter is inside the boundary of the light; if yes then applies the lighting to it, but if not then it leaves the particle unaffected, ID did this for performance reasons.		The '''Offset''' is an additional offset vector from the center of the particle entity or surface. In general, better leave it zero. Try keeping the leaves centered on the particle emitter, as Doom 3's light rendering system calculates whether or not to light the particles by checking whether the particle emitter is inside the boundary of the light; if yes then applies the lighting to it, but if not then it leaves the particle unaffected, ID did this for performance reasons.

	'''Random Distribution''' is just what it says, so you ~~may want to leave that ticked~~.		'''Random Distribution''' is just what it says. Normally, you should always have it enabled, since otherwise all particles will start from the same point.

	'''Speed''' ~~leave that at~~ 0 ~~for~~ the ~~leaves as that~~ is ~~the speed at which the~~ particles ~~move away from the center~~ of ~~the~~ emitter.		'''Speed''' defines how fast particles will move. Set this to zero for stationary particles. '''Direction''' specifies where they move. If you want to send all particles up (e.g. rain), set "cone 0". If you want to spread them along cone (e.g. fountain), then set "cone 45", where the second number is cone angle. If you want to create an explosion, use Outward direction. It is also possible to apply '''Gravity''' to all particles, so that they accelerate down like physical objects. In most cases you should use '''World Gravity''' flag, since otherwise gravity will be directed along local Z-axis of particle emitter.

	'''Size''' is self-explanatory; it's the size of each particle.		'''Size''' is self-explanatory; it's the size of each particle.

	'''Rotation''' is rotation speed of the particle and ~~aspect~~ stretches the particle from the center of the emitter. So leave these 2 alone for leaves.		'''Rotation''' is rotation speed of the particle and '''Aspect''' stretches the particle from the center of the emitter. So leave these 2 alone for leaves.

	Notice that each of these has 2 sliders. This is for time based particles, so one slider is "from" and the second is "to". This is governed over the lifespan, so for example a particle that has sizes 0 to 50 and a lifespan of 10 would mean that it would gradually increase it's size to 50 from 0 over a span of 10 seconds. So for leaves this means that you leave both sliders at the same value. The other values below the speed, size, rotation, and aspect sliders do various things and you can mess around with them if you wish but they are not useful for leaves.

	'''~~Bunching~~''' ~~this~~ determines how ~~much~~ the ~~particles tend to bunch together~~, ~~0 meaning they want to spread out as evenly as possible~~, ~~while~~ 1 ~~means that they bunch together~~ a ~~bit~~. ~~The~~ effect ~~is not actually that noticeable mind~~.		'''cycles''' determines how many times the particle effect will play. Zero value means "infinite number of times".
			In general, a particle system repeats itself prescribed number of times, and every such time is called a "cycle".
			The most common values are: "cycles 1" for a single-time effect (e.g. one-time explosion), or "cycles 0" for an endless continuous effect (e.g. rain).

	'''~~Count~~''' controls how many particles there are, so basically the example shown has 32 particles in total. Obviously the more you have, the more dense the ~~tree~~. This is a slider so slide it around as necessary. Alternatively you can input a value into the box and then press apply down the bottom right.		'''time''' this is how long one cycle of the effect will last in seconds.
			If you want to determine the total duration of the effect, multiply this time by the number of cycles it has.
			For fast effects like fire, smoke, or rain, this is usually about a second.
			For something lazy like leaves randomly flying around, better set this to something like 300.0 (i.e. 5 minutes). This is large enough so that player does not notice randomly disappearing/appearing particles.

			'''bunching''' this determines how much the particles tend to bunch together: 0.0 means they all come out at first instant, 1.0 means that they are emitted evenly over cycle time, 0.4 means that all particles come out in the first 40% time part of the cycle.
			This is not important for a single-cycle particle system.
			To create a continuous particle effect (e.g. rain), set bunching to 1.0. If you set it to any lower value, then particles will come out in bursts, bunched near the beginning of every cycle.
			Note: bunching values over 1.0 are not supported and will cause some particles teleport around randomly.

			'''count''' controls how many particles there are (at any moment), so basically the example shown has 32 particles in total. Obviously the more you have, the more dense the effect is, and the more performance it costs. This is a slider so slide it around as necessary. Alternatively you can input a value into the box and then press apply down the bottom right.

	'''Cycles''' this is how long the effect will last in seconds, If you set "cycles 0.000", it is endless, otherwise repeated so many times. In my case I am creating some ceiling dust that is triggered so am going with 1 or 2 cycles.

	To see the changes you are making, center your camera in the render view on the tree and press {{key\|F7}} and {{key\|F6}}. {{key\|F7}} rebuilds everything and {{key\|F6}} enables animations. Leave it in render view and move the particle editor to the side so you can see the render view (to watch the changes you are making as you make them).

Leave it in render view and move the particle editor to the side so you can see the render view (to watch the changes you are making as you make them).

	You will also notice the "time" input beneath it. This is the lifespan of a particle in seconds. If I may suggest, don't mess with this, as putting it too low will make the particle lifespan visible, as in you'll notice them appearing/disappearing etc. If you put it to something ridiculous, like 99999, then it will load for extremely long, and sometimes not at all. It's best to leave it at 300 (5 minute), as you won't notice the tree leaves changing around every 5 minutes.

	'''Distribution''' This is where things get a little more annoying. You'll notice 3 check dots - rect, cylinder, and sphere. Realistically you'd want to use sphere, but for some reason the algorithm for distribution in the sphere (at least for the leaves) does not work correctly and you get several particles occupying the same spot, which results in z-fighting and generally looks really bad. Now, the rectangle distribution works perfect; particles are properly distributed and there is no z-fighting, but it's a rectangular shape, but can look ok if not too many particles are used. Another alternative is the cylinder distribution. Cylinder distribution works well but annoyingly enough the particles get distributed only on the walls of the cylinder, which means a hole in the middle, so you need to adjust the particle size and cylinder size so that there is no hole in the middle.
