Here you will find documentation on all the descriptions that Cinema 4D currently has. You can list them Alphabetically, by Type or Plugin . The sample Python and C++ code is automatically generated and in some cases may not be 100% correct.

Example Code

The following code does not use the correct values when setting the data. You should check directly in C4D for the correct values that you should use in place of the ones that are shown. This code is just to show you how to access the values for getting and setting the parameters.

Python

import c4d
from c4d import gui
def main():
    obj = c4d.BaseObject(c4d.Opolyreduction)
    doc.InsertObject(obj)
    c4d.EventAdd(c4d.EVENT_FORCEREDRAW)
    
    #You can set parameters two different ways. 
    #First way              
    obj[c4d.POLYREDUCTIONOBJECT_STRENGTH] = 0.1
    obj[c4d.POLYREDUCTIONOBJECT_MESHFACTOR] = 1
    obj[c4d.POLYREDUCTIONOBJECT_COPLANAR] = True
    obj[c4d.POLYREDUCTIONOBJECT_BOUNDARY] = True
    obj[c4d.POLYREDUCTIONOBJECT_QUALITY] = True
    
    #Second way, using the base container.
    bc = obj.GetDataInstance()
    bc.SetFloat(c4d.POLYREDUCTIONOBJECT_STRENGTH,0.1)
    bc.SetInt32(c4d.POLYREDUCTIONOBJECT_MESHFACTOR,1)
    bc.SetBool(c4d.POLYREDUCTIONOBJECT_COPLANAR,True)
    bc.SetBool(c4d.POLYREDUCTIONOBJECT_BOUNDARY,True)
    bc.SetBool(c4d.POLYREDUCTIONOBJECT_QUALITY,True)

    main()
