Hello guys, It's something weird with MCOMMAND_MIRROR in S22.
MCOMMAND_MIRROR
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 unchecked Duplicate Points everything works (in S22).

hi,
this look like a bug, I've opened a bug report
Cheers, Manue
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
May be I can help somehow? I can upload the example scene, if you need it.
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
@m_magalhaes Got it, thanks
Hello guys, This bug is still exists in S24. I made a video to show how it worked before (R21) and now (S22, R23, S24).
https://vimeo.com/558586168
For test I used the script from this page. The only difference I made is decreased value from 1000.0 to 0. It's just for convenience.
value
1000.0
0
This script should mirrors selected object, when settings[c4d.MDATA_MIRROR_DUPLICATE] is False. It works in R21 and doesn't work in any late releases. Could you fix it? I'm still using R21 because of this bug
settings[c4d.MDATA_MIRROR_DUPLICATE]
False
Hi,
our developers are aware of the bug and i can't say when it will be fixed. I understand it's not pleasant for you.
Roger that, thanks again. I wasn't sure that the developers were aware. Sorry for annoy you Cheers
Hi kisaf,
if you switch in the SendModelingCommand from MODELINGCOMMANDMODE_ALL to MODELINGCOMMANDMODE_POLYGONSELECTION it should work until the mirror in object mode is fixed.
Regards Fritz
@fritz thank you very much, it works!
I've missed that one, thanks a lot @Fritz
This have been fixe and will be available in a futur update.
