| − | 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.

| − | Particles can be drawn as quadratically textured polygone or in form of lines:
| |
| − | * <font class="keyword">Quads</font> 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.
| |
| − | * <font class="keyword">Lines</font> 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 <font class="keyword">alpha-channel</font>. However the alpha-channel will not be considered in every drawing-mode (look beneath).

| − | The used texture can be disposed in "tiles" in <font class="keyword">horizontal (U)</font> and <font class="keyword">vertical (V)</font> direction. If <font class="keyword">quads</font> 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.

| − | 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 <font class="keyword">Activate tile-blending</font> 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.

| − | * <font class="keyword">Opaque</font> - the background is repainted (The opacity will be managed by the alpha-channel).
| |
| − | * <font class="keyword">Additive</font> - Color of the particle will be added to the background. The effect will be limited to the maximum brightness (white).
| |
| − | * <font class="keyword">Smooth</font> - The color of the particle will be added to the background, but the less the brighter the background is.
| |
| − | | |
| − | The adjustment <font class="keyword">Additive</font> 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 <font class="keyword">opaque</font>. Particles will be sorted along the Z-axis which extends the calculating procedure.

In most cases it is a good substitute for "real" alpha-shading.

| − | ==Export/Import==
| |
| − | The feature <font class="keyword">export</font> saves the emitter(!) inside a *.PAR-file. This can be exchanged with other users or appended to the own collection.
| |
| − | | |
| − | The feature <font class="keyword">import</font> loads a *.PAR-file and displaces the current emitter.
