pymxs pickle

cannot pickle pymxs.MXSWrapperBase

Getting error while deepcopy pymxs object

which object do you want to copy and how? please give a code example... otherwise the question is too abstract and does not make general sense.

[pradeep_cher]

import pymxs
mxs = pymxs.runtime
cameraName = "VRayPhysical_configurator_animated_lhd"
node = mxs.getnodebyname( cameraName )
dict1 = {}
import copy
dict1["cam"] = copy.deepcopy(node)
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "C:\3dsmax2023x64\3ds Max 2023\Python\lib\copy.py", line 161, in deepcopy
rv = reductor(4)
TypeError: cannot pickle 'pymxs.MXSWrapperBase' object

This will work for Max2019 and throwing error with Max2023

you can't use Python copy method to copy MAX objects or values. You must use MXS copy or deepcopy for this:

mxs = pymxs.runtime
mxs.copy (node)
## or mxs.deepcopy for array values, for example

Than you @denisT.MaxDoctor , this worked
