Hi Paul,

I just noticed this created in $HIH:


However I'm on Linux so… I'm guessing some Windows-specific code snuck in?

That's created as a single directory. Also given how big that could potentially be, is $HOME/houdini17.5 the best place for it? Why not $TEMP? I could be missing something though.

RFE: DnD parms into Wedge TOPs May 11, 2019, 11:53 a.m.


Currently there is no easy way to get parms into a Wedge TOP other than doing a Drag and Drop and choosing “Absolute reference” then manually editing out the expression bits. The Parm chooser dialog is waaaay too slow in a file with 100's of nodes and many parms on each node.

RFE: Please add a new DnD “drop” action “Parm Path” that simply types in the path to the parm.

Q: Wedging preserving original value implemented? May 11, 2019, 11:49 a.m.

Seems to work now thanks!

I do notice that if I use the Orient parameter from the Torus (as an example) and use its String value (i.e. x, y, z) I will get errors on the Wedge node:

Error running callback 'onDeselectTask': The attempted operation failed.
Invalid menu item

Traceback (most recent call last):
File "/opt/software/hfs17.5/houdini/pdg/types/utils/", line 92, in onDeselectTask
File "opdef:/Top/wedge?PythonModule", line 87, in restoreAllCallback

def _set(*args): return _hou.ParmTuple__set(*args)
OperationFailed: The attempted operation failed.
Invalid menu item

The Int version of that parm works though.

Calling parm.set(“x”) etc does work, so not sure why it's failing.

I do see where “bad” data could be entered in the Wedge top though when wedging strings, perhaps this could be a little more artist friendly if that happens?
