save selected nodes as

[Follyx]

is it in some way possible to save just selected nodes to a hipfile without any rearrangement or similiar.

Maybe a python script?

select the nodes

ctrl+C

open new Houdini session

ctrl+V

[Follyx]

yes, of course. I ment without a new session.

I RFE'd this at some point, it'd be super handy.

Here is some code you can put into a shelf tool (only tested under Linux):

import os, time, subprocess

sel = hou.selectedNodes()
parentNode = "hou.node('/obj')"
filePath = "/tmp/myTempNodes"
p = sel[0].parent()
p.saveChildrenToFile(sel,"",filePath)

if p.parent is not hou.node("/obj"):
    parentNode = "hou.node('/obj').createNode('%s','newparent')" %(p.type().name())
    
saveCode = '"' + "import os, time; newParent = "+parentNode+"; newParent.loadChildrenFromFile('"+filePath+"'); newPath = '/tmp/hipFromSel_' + time.strftime('%Y%m%d_%H%M%S') + '.hip'; hou.hipFile.save(newPath)" + '"'

pyCmd = os.environ["HFS"] + '/bin/hython -c ' + saveCode
os.system(pyCmd)
print "Saved new hip file"

You can save nodes to a file using saveChildrenToFile(); then use loadChildrenFromFile() to read them in as they were saved.

I save them in HDA, then extract where I need. If merging from HIP is the final goal of such "hip-snippets", just save in HDA too.

filePath = "D:/test/myTempNodes.cpio",Need to add suffix，Only then did it run successfully
