Hi all, I'm trying to expose the “Tile Texture Filename” and “Save to Disk” of a HeightField Output SOP to a HDA interface. When I do, it appears that the filename parm is set correctly, but when I click “Save to Disk” from either the HDA or the HeightField Output node I get this error:

Traceback (most recent call last):
File “<stdin>”, line 18, in <module>
File “CPROGRA~1/SIDEEF~1/HOUDIN~1.405/houdini/python2.7libs\hou.py”, line 40546, in unexpandedString
return _hou.Parm_unexpandedString(*args)
OperationFailed: The attempted operation failed.
Cannot get unexpanded string for parms with keyframes

I'm using drag'n'drop to expose the parms in the type editor window.

Thoughts?

TNKS!

Hi,

This was due to a bug in HF_Output, this issue should be fixed in today's daily build.
