==General==
[[Image:17_Par11_e.jpg]]

The settings of the particle-system beside the preview-area will be adjusted by the flag "system". They influence all particle-emitters.

==Scene for preview==
[[Image:17_Par21_e.jpg]]

You can choose a scenery for preview which is positioned in the back. It serves as an orientation for the particle aspect in the foreground, but cannot be addepted. The adjustement for the particles is to be executed in the foreground scenery. So you can use a particle system in several sceneries (but always at the same position, for example snow and rain).

==Camera angle==
[[Image:17_Par25_e.jpg]]

Particles are "real" 3D-objects, that means they move in an area defined by three coordinate-axis (x,y,z) and are observed by a virtuell camera. At the beginning a particle-emitter is located at the point of origin and the camera is located 3 units away from this point on the z.-axis. The camera is geared to the direction of the positive Z-axis, to observe the point of origin at 3 units range, -3.0 has to be adjusted (presetting).

==Lead time==
[[Image:17_Par10_e.jpg]]

Before it is shown for the first time, the particle-system has to be fast-forwarded by the adjusted lead-time. Otherwise (for example) rain would restart to fall downwards the screen-border at every re-enter.

==Show force==
[[Image:17_Par32_e.jpg]]

Every emitter can be affected by a force field. The activation of the option shows us the exactly position and direction of the force inside the preview area.

	Each widget contains two red lines (except the one for "Emission Count" which only has one). Grab the nodes to move them. If you set them to different values, particles will receive a random property value from the range in-between, making each particle more or less unique – thus creating a diverse and "chaotic" emitter output. Click on the red line to add a new node. This allows you to turn the line into a curve and let the value change over the duration of one emitter loop. You can delete a node by selecting it and pressing the "Delete" button. Pan the timelines vertically with the right mouse button (if possible). The two input fields below show the horizontal position of the selected node in the timeline (between 0 and 1) and its value.

−	The last property is <span class="inlinecode">Color</span>. This allows you to add a tint to the particles. The timeline looks a bit different but you can still add new nodes to it and assign an individual color to each of them. The particles will then change their color during their lifetime. Since you define a tint color, adding a white node does not change the original color. Coloring is easiest when working with a white texture.

Particle systems are added to objects via [[Scenes_and_Objects#Components|components]] and the particles will show up in the viewport, if the second of the two green play buttons above the viewport is enabled.
 * Assigning a particle system to an interface button works just like adding it to a scene object.

 Each particle is generated with a set of properties which define its behaviour. These emission parameters are set up via timeline input widgets (see image). The width of the widgets corresponds to the duration of one emitter loop. Read the description of "Emitter Duration" and "Emitter Loops" above for more about loops.
