How to delete/replace a String parameter reference in python

Hi,

When a string parm is set with a hscript reference to another parameter, how can we delete or replace this reference?

If I simply do set, it will change the value of the referenced parameter and deleteAllKeyframes() does nothing…

The only solution I found at this time is the next:

p = hou.parm('/obj2/geo2/file1/file')
if p.getReferencedParm() != p:
    p.revertToDefaults()
p.set('`chs("../../geo/file1/file")`')

Or change this to an expression…

Am I wrong or there is no other way?

Thanks

I guess in this case you need to use the setExpression() function, instead of the regular set().
it's documented here: https://www.sidefx.com/docs/houdini/hom/hou/Parm.html [www.sidefx.com]

cheers
