Action: Control Morphing
This action gives control over the morphing of generated objects. It can do so either by acting directly on the particle, or by controlling a Morph modifier.
The Action's interface looks like this:
This sets the operation mode of the Action. There are two options:
The Action will directly alter the particle morphing. It does NOT require a Morph modifier. This lets you control morphing at a precise point without having to work indirectly through a modifier.
In this case the Action will let you control the operation of a Morph modifier in the scene.
Control Modifier Mode
This field is only available if you choose 'Control Modifier' in the Mode setting.
This field accepts a Morph modifier which you drag into the field from the Object Manager. Without a linked modifier, you cannot access any of the other parameters and the Action will have no effect. In addition, in the modifier's interface the Mode parameter MUST be set to 'Action-Controlled'. If it is set to 'Independent' the modifier will simply work on its own like any of the standard Cinema 4D modifiers and the Action will have no effect on it.
Effect on Particle
This drop-down menu has two modes:
Modifier Will Affect Particle
In this mode the modifier will start to influence the particular particle which is affected by this Action. Once the particle is influenced by a modifier, that influence will continue until the effect is turned off (e.g. by another Action).
Note that whether the modifier actually has any effect on the particle will depend on the modifier's parameters and especially on its falloff. Even if the modifier is set to effect a particle, it may have no effect on it if the particle never enters the field of effect of the modifier.
Modifier Will NOT Affect Particle
In this mode, the modifier's influence on the particle will be turned off and the modifier will never affect the particle, unless it is turned back on again (e.g. by another Action).
Direct Change Mode
These are the parameters which can be changed in 'Direct Change' mode.
Change Target Index, Morph Target Index
These settings work identically to the settings 'Change Morph Target' and 'Morph Target Index' in the morph modifier. Please refer to the Morph modifier for details.
Set Morph Amount
If this switch is checked, the amount that the object is morphed will be changed to the value in the 'Morph Amount' setting.
The amount to morph an object associated with the affected particle.
Drag the particle Group object(s) you want to be affected by the modifier into the 'Groups Affected' list. If the list contains at least one group, groups not in the list will not be affected. But if no groups are in the list, all groups are affected.
