Hi all,

I need to transfer material from one subnet to another subnet
for example
I have Subnet A and Subnet B
inside of Subnet A i have sphere geo named A
and inside of Subnet B also i have sphere geo named A

i used this python script to transfer material

import hou

def getNodeList(Node_A,Node_B):
getObjectsInSubnet_A=hou.node(“/obj/”+Node_A)
getObjectsInSubnet_B=hou.node(“/obj/”+Node_B)
for child in getObjectsInSubnet_A.children():
t=child.name()
for allObjects in t:
allShopPath=hou.parm(“/obj/”+Node_A+“/”+allObjects+“/shop_materialpath”).eval()
print allShopPath
getObjectsInSubnet_B.setParms({“/obj/”+Node_B+“/”+allObjects+“/shop_materialpath”:allShopPath})



and it is working fine and my issue if i rename both sphere geo to AA(or more than one letter)
its not working giving this error

Traceback (most recent call last):

File “<console>”, line 1, in <module>

File “D:\Sab_VFX\RnD\Houdini\RnD\python\hou_script\getNodeList.py”, line 10, in getNo

allShopPath=hou.parm(“/obj/”+Node_A+“/”+allObjects+“/shop_materialpath”).eval()

How to sort this or any problem with python script
or any other method is there

allShopPath=hou.parm(“/obj/”+Node_A+“/”+allObjects+“/shop_materialpath”).eval()

maybe you can get the Node and use evalParm() instead of parm( .. ).eval()

hi Guys found a way adjusted script litle


import hou

def materialTransfer(getNode_A,getNode_B):
subNetA=hou.node(“/obj/”+getNode_A)
subNetB=hou.node(“/obj/”+getNode_B)
for allNodes in subNetB.children():
getAllNodes=allNodes.name()
#print getAllNodes
allShopPath=hou.parm(“/obj/”+getNode_A+“/”+getAllNodes+“/shop_materialpath”).eval()
subNetB.setParms({“/obj/”+getNode_B+“/”+getAllNodes+“/shop_materialpath”:allShopPath})
print (“Material Transfered succesfully without any Head ache”)


but its taking too much time cook materials

maybe you can get the Node and use evalParm() instead of parm( .. ).eval()

thanks Zarti

let me now its woking let me see evalParm()
