[[Image:17_Par33_e.jpg]]

In the flag "Rendering" of a particle emitter some presettings are adjusted which concern the drawing of the particles and do not associate directly to the formation and "living" of the particles.

==Type of particle==
(A change directly restarts the particle-system!)

Particles can be drawn as quadratically textured polygone or in form of lines:
* Quads draw a quadrate around the position of the particle which can be coated with a texture. Every particle can use a different section of the chosen texture.
* Lines are drawn from the last position of a particle to the currentl position. This means the lines are the longer the faster the particle moves.

== Texture of particle ==
The look of the particle is defined by this texture. The texture may be colored and can copntain an alpha-channel. However the alpha-channel will not be considered in every drawing-mode (look beneath).

{| style="border-collapse: collapse" width="100%" border="1" cellpadding="4"
| width="100%" bgcolor="#FF9999" |
Important: A texture '''has to be''' defined in the editor. The preset texture is only used to present something if a new emitter is created but it will '''not''' be saved in the VED or VIS file.

==Partition==

The used texture can be disposed in "tiles" in horizontal (U) and vertical (V) direction. If quads are adjusted as a particle type, every particle uses a random tile as texture. Thereby variety is created. Besides there is a determination, how many of the arising texture-parts should be used (starting with '''zero''' continuously and numbered line by line). The adjustment '''-1''' integrates every texture-parts.

== Tile-blending ==
[[Image:17_Par34.jpg]]

Instead of assigning every new particle a random part of the texture (which will be kept by this one), it can be cross-blended between the texture-parts by and by. This feature can be activated through the checkbox Activate tile-blending and can be navigated by the [[Particle life#Size of Particles|curve]] beside.

==Modus of Drawing==
The modus of drawing defines how the texture of a particle is to be associated with the background during the calculating.

<blockquote>

</blockquote>

* Opaque - the background is repainted (The opacity will be managed by the alpha-channel).
* Additive - Color of the particle will be added to the background. The effect will be limited to the maximum brightness (white).
* Smooth - The color of the particle will be added to the background, but the less the brighter the background is.

The adjustment Additive creates an interesting "burn-out" or "outshine"-effect is generated where a lot of particles overlap. Just try it!

The alpha-channel is considered only in the drawing-modus opaque. Particles will be sorted along the Z-axis which extends the calculating procedure.

{| style="border-collapse: collapse" width="100%" border="1" cellpadding="4"
| width="100%" bgcolor="#FF9999" | Hint: If Additive or Smooth are adjusted as thedrawing-modus, the parts of a particle which are the darkest seem to be the most translucent. In most cases it is a good substitute for "real" alpha-shading.
|}

==Export/Import==
The feature export saves the emitter(!) inside a *.PAR-file. This can be exchanged with other users or appended to the own collection.

The feature import loads a *.PAR-file and displaces the current emitter.
