python Shelf tools & scripts collection

[younglegend]

 

Hey guys! I'm starting this thread to share few shelf scripts i use and came across, during my houdini journey. Please feel free to add in more!

 

# ADD NODES/OBJECTS TO MANTRA (Customisable)

Select node(s) and click on the script to add it to mantra's force object/matte object etc. You can customise where to add by changing the parameter name (line 22) 

import hou
selection = hou.selectedNodes()
names = [n.name() for n in selection]
my_list = “”
if len(selection) < 1 :
my_list = "nothing selected, please select at least one object"
else:
a=1
for sel in selection:
my_list = my_list + "\n" + "selected object " + str(a) + ":" + sel.name()
a=a+1
hou.ui.displayMessage(my_list, buttons=('OK',))
length = len(selection)
print "Number of nodes selected: " + str(length)
paths = [n.path() for n in hou.node('/out').allSubChildren()
if n.type() == hou.nodeType('Driver/ifd')]
selected = hou.ui.selectFromTree(choices=paths)
mantras = [hou.node(path) for path in selected]
for m in mantras:
m.parm('matte_objects').set(' '.join(n.name() for n in hou.selectedNodes()))
#CHANGE PARAMETER NAME AS REQURIED
print ("Selected mantra nodes : ") + m.name()
new_name=' '.join(names)
hou.ui.displayMessage("( "+ (new_name) + " ) – added to selected mantra(s) matte objects.", buttons=('*OK*',))

 

#SETUP DELAYED LOAD

Select node(s) and execute. It'll create procedural shader and setup all the parameters. Works on all nodes with 'file' parameter.

#function for node variable: return type, description and name
def extract_getTypeName(node):
nodetype = node.type()
description = nodetype.description()
type_name = nodetype.name()
return type_name
#show selection tuple names
selection = hou.selectedNodes()
print len(selection)
my_list = “”
if len(selection) < 1 :
my_list = "nothing selected, please select at least one object"
else:
a=1
for sel in selection:
my_list = "selected object : " + sel.name()
a=a+1
hou.ui.displayMessage(my_list, buttons=('OK',))
#for each object in selection
lenght = len(selection)
print "DONE!"
for i in range(lenght):
#create python variable for selected node
selected = hou.selectedNodes()[i]
if selected:
meshop=hou.node('/shop');
meshop=meshop.createNode('vm_geo_file');
meshop.setName('delayed_load_shop_1', 1)
targetdshop=meshop.path();
meobj=hou.node('/obj')
meobj=meobj.createNode("geo");
meobj.setParms({"shop_geometrypath":targetdshop});
meobj.setName('DELAYED_load_geo_1', 1)
targetfile=selected.parm('file') or selected.parm('sopoutput')
mefile=meobj.node('file1')
meobj.parm("geo_velocityblur").set(1)
meobj.parm("vm_forcegeometry").set(0)
meshop.parm("file").set(targetfile)

#Add Null node by pressing 'N' key

selected_nodes = hou.selectedNodes()
for node in selected_nodes:
parent = node.parent()
name_node_selected = node.name()
null = parent.createNode(‘null’,’OUT_’ +
name_node_selected)
null.setInput(0,node)
macolo = hou.Color((0,0.5,0))
null.setColor(macolo)
pos = node.position()
null.setPosition(pos)
null.move([0,-1])
#flags
null.setSelected(True,True)
null.setDisplayFlag(True)
null.setRenderFlag(True)
