Mirror without duplicate using `MCOMMAND_MIRROR`
-
Hello guys,
It's something weird withMCOMMAND_MIRROR
in S22.This script (thanks to m_adam) duplicates and mirrors the object.
import c4d def main(): # Checks if selected object is valid if op is None: raise ValueError("op is none, please select one object.") # Defines some general settings, take care MDATA_MIRROR_VALUE, MDATA_MIRROR_SYSTEM and MDATA_MIRROR_PLANE settings = c4d.BaseContainer() settings[c4d.MDATA_MIRROR_DUPLICATE] = True settings[c4d.MDATA_MIRROR_SELECTIONS] = True settings[c4d.MDATA_MIRROR_ONPLANE] = True settings[c4d.MDATA_MIRROR_WELD] = True settings[c4d.MDATA_MIRROR_TOLERANCE] = 0.01 # Corresponds to MDATA_MIRROR_VALUE, MDATA_MIRROR_SYSTEM and MDATA_MIRROR_PLANE value = 1000.0 system = 0 # 0 = Object, 1 = World plane = 1 # 0 = XY, 1 = ZY, 2 = XZ if not 0 <= system < 2: raise ValueError("System can only be 0 or 1") # Buffer position vector pos = c4d.Vector() # Calculates Local (Object) coordinates if system == 0: globalMatrix = op.GetMg() if plane == 0: pos = globalMatrix.v3 elif plane == 1: pos = globalMatrix.v1 elif plane == 2: pos = globalMatrix.v2 settings[c4d.MDATA_MIRROR_POINT] = globalMatrix.off + pos * value settings[c4d.MDATA_MIRROR_VECTOR] = pos # Calculates World coordinates elif system == 1: if plane == 0: pos = c4d.Vector(0.0, 0.0, 1.0) elif plane == 1: pos = c4d.Vector(1.0, 0.0, 0.0) elif plane == 2: pos = c4d.Vector(0.0, 1.0, 0.0) settings[c4d.MDATA_MIRROR_POINT] = pos * value settings[c4d.MDATA_MIRROR_VECTOR] = pos # Send the Modeling Operation res = c4d.utils.SendModelingCommand(c4d.MCOMMAND_MIRROR, [op], c4d.MODELINGCOMMANDMODE_ALL, settings, doc) c4d.EventAdd() if __name__ == "__main__": main()
However, if I change
settings[c4d.MDATA_MIRROR_DUPLICATE] = True
to
settings[c4d.MDATA_MIRROR_DUPLICATE] = False
Script doesn't make anything.
In R20 it works.
Is it ok? Is there any way to just mirror the object without duplicate it?P.S. Also, if I use
Mirror
(https://help.maxon.net/index.html#5633) with uncheckedDuplicate Points
everything works (in S22).Cinema 4D S22.118 Windows 10

Hi, I've just tested this script in R23. It doesn't work :(
One of my own scripts cannot work without this function.
Guys, you're really awesome! I love C4D, and hope you can fix it :DMay be I can help somehow? I can upload the example scene, if you need it.

hi,
this will be probably fixed for futur updates but i doubt that this will be fixed for previous version.
The only way to go is to create your own function to mirror the polygon. This can be really long if you want to support uvs, texture, selection tag etc.
Sorry for the inconvenient.
Cheers,
Manuel
