This modifier attracts particles to itself or to other objects. It can carry out user-specified actions when the particle approaches the target.
This modifier has the following sections:
For the 'Groups Affected', 'Mapping', and 'Falloff' tabs, and for the buttons at the bottom of the interface, please see the 'Common interface elements' page.
Uncheck this switch to disable the modifier.
Independent [default setting]
In this mode, the modifier will work in the same way as a standard Cinema 4D particle modifier: particles will be affected if they come into the field of effect of the modifier. X-Particle Actions have no effect on the modifier in this mode.
In this mode, the modifier will only act on a particle when told to do so by an Action. Until that point, the particle will not be affected, but once activated for a particular particle, the modifier will continue to influence it as long as it is in the field of effect of the modifier. The modifier's effect on a particle can be halted by means of another Action, if desired.
This modifier has two modes of operation, which are controlled here. The options are:
This is the default mode. Here, the modifier takes complete control of the particle movement and if you add another modifier which also influences particle speed and direction (e.g. Turbulence) you will find that it has little or no effect on the particle. This is the only mode that was available in X-Particles 3.5.
In this mode the change in velocity caused by this modifier contributes to, but does not control, the final particle velocity. Adding a modifier such as Wind or Turbulence will also contribute to the final result. This is the mode to use if you want to add some other kind of movement to the particle as well as rotation.
This is the force applied to the particle to attract it to the modifier.
This will accelerate the particle as it moves towards the modifier. Because the particle speed can become very high, very quickly, you can limit the speed to the value in the 'Speed limit' setting.
The maximum speed the accelerated particles will have.
From this menu you can select which of the objects in the 'Attractors' list will be used to attract the objects. Note that if the list is empty, the particles are attracted to the position of the modifier itself and this menu is not used.
The options are:
The particles are attracted to the nearest object to them. Depending on particle position, different particles may be attracted to different objects. Also, if the objects are animated, the object which is nearest to a particle may vary over time.
The particles are attracted to the object furthest away from them. Depending on particle position, different particles may be attracted to different objects. Also, if the objects are animated, the object which is furthest from a particle may vary over time.
The positions of all the objects in the 'Attractors' list are averaged and the particles will be attracted to the resulting location. Almost certainly, this will be somewhere in the 3D world other than an actual object position.
The particles will be attracted to a specific object in the list, where the first object in the list has an index of 0, the second an index of 1, and so on. Use the 'Index' parameter to select the object to use.
Each particle will be attracted to a randomly-selected object from the list.
The object to use if 'Object Select' is set to 'Object Index'.
Drag the objects you want to use into this list. If you leave it empty, the particles will be attracted to the position of the modifier itself. This is the same behaviour as in previous versions of the modifier, which did not use an object list.
You can drop a Mograph Cloner or Matrix object into this list and all clones or matrix elements will be used as attractor objects. Note that if you select 'Object Index' in the 'Object Select' drop-down menu, each clone or matrix element counts as an object. That is, if you have a Cloner with five clones in the list, followed by a primitive cube, the cube would actually have an object index of 5 (the clones would be objects 0 to 4).
Range Less Than
The Actions in the 'Actions' list will be triggered while the particle is closer to the Attractor than the value in 'Range'.
Range More Than
The Actions in the 'Actions' list will be triggered while the particle is farther away from the Attractor than the value in 'Range'.
The minimum distance the particle must be from the modifier for actions in the 'Actions' list to be triggered.
You can drag any action into this list. When the action is triggered depends on the 'Range Mode' setting (see above).
Clicking this button will add an action to the scene and drop it into the Action list.
