Python Effector

Introduction

The Python Effector is used to create custom Effector for a MoGraph object. It can be found in the MoGraph -> Effector menu.

The Python Effector is implemented through an EffectorData which is not available in Python. Take a look in the C++ doc for more information. The Python Effector offers two modes to execute code:

1. Parameter Control: called for each clone.

2. Full Control: called only one time to handle all clones at once.

Note

The Python Effector should not create/modify objects in the scene.

Example

# This code is used in a Python Effector
import c4d

def main():
    md = c4d.modules.mograph.GeGetMoData(op)
    if md is None:
        return 1.0

    # Generator object, same as c4d.modules.mograph.GetGenerator()
    print(gen)

    # Other variables are also available in a Python effector
    print(doc)   # Document where the effector is located
    print(op)    # Effector object

    return 1.0

Methods

main()

Override - Mandatory method, used to set MoGraph data through c4d.modules.mograph. It can be called multiple time per frame.

Variables

Next variables are defined in a Python Effector scope (in all functions even yours):

• doc: BaseDocument : The document hosting the Python Effector.

• op: BaseObject : the Python Effector.

• gen: BaseObject : the MoGraph Generator (e.g. the cloner object which executes the Python Effector).
