## Effector

### Strength

Parameter ID: `MGREEFFECTOR_STRENGTH` · Range: [-∞..+∞%]

The **Strength** value is a measure of the Effector’s overall strength. As with other Strength values, this can also be set to less than 0% or greater than 100%.

### Selection

Parameter ID: `MGREEFFECTOR_SELECTION`

![Image: 018406.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/018406.jpg)\
On the left, a Step effector is shown without selection; on the right, it is shown with a selection applied. A Step effector was chosen here as an example of selection; otherwise, selections work differently depending on the type of effector.

A [MoGraph Selection](https://help.maxon.net/c4d/en-us/Content/html/TMGSELECTION.html.md) or [MoGraph Weightmap](https://help.maxon.net/c4d/en-us/Content/html/TMGWEIGHT.html.md) tag can be dragged into this field or placed automatically by selecting a Cloner object and an existing MoGraph selection/weighting, and creating an Effector.

The Effector will then work as follows, depending on the tag’s settings:

- **MoGraph Selection** tag: Will only affect the clones belonging to the selection.
- **MoGraph Weightmap** tag: The clone weighting (values between 0% and 100%) saved in the tag will be multiplied with the effector strength.

### Effectors

Parameter ID: `MGREEFFECTOR_EFFECTORS`

Drag all Effectors into this list that should be unified or grouped in the ReEffector. This list works exactly like the Effector list in the clone-generating object (e.g., Cloner or Shatter object). However, the ReEffector can also define exactly which effect should be applied using the **Parameter** tab settings.
