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
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.
