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