Hello guys,

I'm having a problem to get a StringParmTemplate working.
I would like to create a parameter where the user is able to pick a textures path for further processing.

That is what I have:
parms.addParmTemplate(hou.StringParmTemplate('texpath', 'Texture Path', 1, "", string_type=hou.stringParmType.FileReference, file_type=hou.fileType.Directory))

But unfortunately it not letting me pick a folder and asking for a file instead.
I searched the forum, looked up the documentation and googled with no luck.

Hope someone of you can help me with this issue!

Cheers,
Jakob

Hi Jakop,
yes it seems to be like that. its a pain…
I would also love to see a solution for this.
Currently i copy paste directories
or select a file and delete it from the string.

Greetings

Olaf

Thank You Olaf,

I already was pretty desperate about this issue.

But it's quite unbelievable. Why isn't something so simple impossible, though it works like a charm with
hou.ui.SelectFile([..]file_type=hou.fileType.Directory[..])

Why isn't SESI implementig it into all file parameters!? Especially, because the file picker button is calling a hou.ui procedure anyway.

Seems to me, that I have to build a workaround with a hou.ui popup myself.

Cheers und viele Grüße!

Hello everyone,

this is my solution I came up with:

These are the parameters created. The Button is calling the texpath function.

parms.addParmTemplate(hou.StringParmTemplate('texpath', 'Texture Path', 1, join_with_next=True))
parms.addParmTemplate(hou.ButtonParmTemplate('texpath_btn', '...', script_callback="hou.session.texpath(hou.node('.').path())" , script_callback_language=hou.scriptLanguage.Python))

This function is written to the Houdini Source module. Taking the triggered node as a variable and setting the string with the path into the node holding the parameter.

def texpath(node):
    texpath = hou.ui.selectFile( title='Choose texture folder for import...', file_type=hou.fileType.Directory, 
    chooser_mode=hou.fileChooserMode.Read)
    hou.node(node).parm('texpath').set(texpath)
