Hello there,

I know that I can use ch() function to get current value of a certain channel.
But how can I get the default value instead of current value?

There might be a better way, but I managed to get at it with Python using parmTemplate:-


#Node which has the parm you want to get default of
n = hou.node(“/obj/geo1/attribwrangle4”)

#Get the default ('count' is just the name of the parm I am grabbing)
default = n.parm(“count”).parmTemplate().defaultValue()

#return the value
return default

Why you need expression for that? Default value is always constant so why not to type it by hand.

Maybe if the default value is being set dynamically by an automated UI builder? Or maybe a little script to reset all parms to default or something? Could be anything!
