The two knots are set at 10% and 90% along the gradient. To control the distribution you would need a gradient with two knots, like so: For example, suppose you have three child objects arranged like this in the object manager: It is the position of any knots that is important.
To use this gradient the colours are not used at all.

It has no effect if the Generator only has one child object. This is a gradient which becomes available if 'Use Multiple Child Objects' is set to 'Use Gradient'. The seed value for the random selection of objects when you select 'Randomly' from 'Use Multiple Child Objects'. If the Generator only has two child object and you enter a '3' here, nothing will be generated. It's up to you to make sure the index is valid. This is only available if you select 'Choose by index' from the 'Use multiple child objects' drop-down. Use Gradient: with this option the 'Object Distribution' gradient is available and you can use that to control the distribution of objects.
For example, group 1 particles are associated with the first child object of the generator, group 2 particles with the second child object, etc.
Assign by Group: child objects are assigned to each particle according to the particle's group. This may not appear to be a very useful mode, but the great advantage is that you can change the object generated with an Action, so when a particle satisfies the required criteria it can be made to generate a different object. The first valid child is given the index of 1, the second is 2, and so on. Choose by Index: in this mode, you can choose which child object is to be generated. First Child Only: the Generator will ignore other child objects and just generate the first valid child. Randomly: for each particle the Generator will choose one of the child objects at random. In other words, if you have a Generator with three child objects - a cube, a sphere, and a cone - the first particle will generate a cube, the second a sphere, the third a cone, the fourth a cube again, and so on. Sequentially : for each particle the Generator will generate one of its child objects in turn. This setting determines how the generator will deal with more than one child object. You should normally leave this switch checked unless you are sure you want to turn it off. If it is unchecked, no object will be generated for newly-created particles until this switch is checked again, or until object generation for a particle is turned on by an Action. If this switch is checked, an object will be generated for each particle as soon as it is created. Add EmitterĬlick this button to create a new emitter and add it to the 'Emitter' link field. Until you have done so, you will not be able to access any of the other settings in the Generator. Drag an emitter object into this field to do that. Parameters General quicktabįor objects to be generated from particles, you must tell the Generator which emitter it will work with. The object's interface includes these sections:įor the 'Groups Affected' tab, and for the buttons at the bottom of the interface, please see the ' Common interface elements' page. For more details, please see the 'Use Multiple Child Objects' section below. What if the generator has more than one child object? There are several options to handle this. It’s up to you to make sure that there is a valid child object or objects to generate. You may not even see particles in the editor, depending on the setting in 'Draw Mode'. Note that if you turn on object generation, but the Generator doesn't have any valid child objects, nothing will be generated at all. Playing the animation will now generate multiple copies of the child object(s). Then ensure that 'Draw Mode' is set to 'Geometry Only' or 'Geometry and Particles'. Nor will it generate objects such as particle modifiers, since these have no effect on the scene (this is a restriction within Cinema 4D, not X-Particles).įor any valid object create the object and make it a child of the Generator object. For example, it doesn't make much sense to generate multiple Sky objects, so X-Particles won’t let you do that. The Generator will generate almost any kind of object, though some are excluded. If you want objects to be associated with those particles, you will need to add a Generator object. This is needed because the Emitter object only generates and manipulates particle data. The Generator object is responsible for generating objects in the scene.
