add a Node to diferent Geo Sop at same time.

[vhalldez 46]

Hi friends...I have more than 10024587515 Geo nodes on my SOP network...I need to add a Normal Sop on the final network of everything, I have to do it one by one? Or Houdini give me a way to do automaticly? If yes, which?

Thank you for all

For stuff like that use Python.

Create a shelf tool with the following code:

obj = hou.node("obj/")
geos = obj.children()

for geo in geos:
    last = geo.children()[-1]
    nml = geo.createNode("normal")
    nml.setInput(0, last)
    nml.moveToGoodPosition()
    nml.setRenderFlag(1)
    nml.setDisplayFlag(1)

If all the geo nodes are on the same hierarchy level (e.g. "/obj/geo_nodes/geo_0","/obj/geo_nodes/geo_1","/obj/geo_nodes/geo_2",...), you can create a new "geo" node and then merge everything using an "object merge" node with the wild card syntax:

Be sure to check the "Create Per-Primitive Path" Attribute. Then you can loop over the packed prims via the path and unpack, add normals, repack the geo while still keeping the same path hierarchy.
