Hello,

i have set up a network where i have several group nodes which all end at a switch node.
I was wondering how can i check with an expression in Hscript wheter each one of my group nodes has an input or not.?

it should be smth like ex. if(group1/“smth”)==1,1,0)

you can check if there is an input by using the opninput() expression.
something like
if(opninput(“../group1”)>0, 1, 0),
alternatively you could use python and do something like this:

node = hou.node('/obj/geo1/group1")
if not node.inputs() == None:
print “hello”


Or you could try to see if there is incoming geometry by using the npoints() or nprims() expressions and do something like this:
if(nprims(“/obj/geo1/sopnode”) > 0, 1, 0)

cheers,

Manu
