ROP Network with Conditional String

[gemini]

Hi,

I have a simple problem with this python code ( part of a larger script ). It creates a rop network, opens a stored preset for it. And changes a parameter label.

It works. What is wrong that the script clears the conditional string of the rop network. Does anyone has an idea ?

Thanks in advance !

The script :

rop = hou.node('/obj').createNode('ropnet')
drop_preset_name = 'dROP2'

op_path = rop.path()

cmd = 'oppresetload %s "%s"' % (op_path, drop_preset_name)
hou.hscript(cmd)

# set the active toggle label as sim and as render , with version
is_sim = rop.userData( 'is_sim')
parm_obj = rop
ptg = parm_obj.parmTemplateGroup()
parmname = 'active'
pt = ptg.find( parmname)
if is_sim == '1':
    rop.parm('issimtoggle').set(1)
    pt.setLabel('Active / [ SIM ]  /  '+self.version)
elif is_sim == '0':
    rop.parm('issimtoggle').set(0)
    pt.setLabel('Active / [ RENDER ]  /  '+self.version)
ptg.replace( parmname, pt)
parm_obj.setParmTemplateGroup(ptg)

I would guess that it is going to clear the user data because you are creating a new node each time. What if you check if the rop exists and fetch the node rather than creating it each time. Then your UserData might persist.

I'm just guessing at the name generated by the create node, you may have to control the name by specifying it directly upon creation.

rop = hou.node('/obj/ropnet1')
if rop == None:
	rop = hou.node('/obj').createNode('ropnet', 'ropnet1')

THX , but sadly not.

These lines clearing the conditional string:

ptg = parm_obj.parmTemplateGroup()
parmname = 'active'
pt = ptg.find( parmname)
ptg.replace( parmname, pt)
parm_obj.setParmTemplateGroup(ptg)

 

It seems like a bug. Isn't it ?
