Separate fbx part

[davidyannick]

I've downloaded free Utopia kit from kitbash 3D, I've created in vex groups with parts

s@dir;
s@lname;

splitpath(@name,@dir,@lname);

So if I use a for each connected piece with @dir  as piece attribute it works, but I'd like to generate a blast node for each group in Python, but with Python SOP I can't create nodes, so how can I create blast nodes (linked to my wrangle) a blast for each @dir ?

Thanks for your help

you have to use Python Source Editor, or save it as a shelf tool with python script in it. python SOP can only manipulate things inside of it's own object.

I've tried with shelf but I didn't find tthe way to read priimitive attributte and make a for ... in prim from the shelf

thanks for your help  here is a draft. it works

 

acNode=hou.node('/obj/geo1/attribwrangle1')
ac=hou.node('/obj/geo1/attribwrangle1').geometry()

l=ac.primStringAttribValues('dir')
   
print(set(l))

root=hou.node('/obj/geo1/')

for n in set(l):
     b=root.createNode('blast',n)    
     b.parm('group').set('@dir='+n)
     b.parm('negate').set(1)
     b.setInput(0,acNode)
     b.moveToGoodPosition()
