I don't know the specifics of this package, but for a regular Python package you need PYTHONPATH variable and not PATH

import subprocess subprocess.Popen(['gplay', '/path/to/your/geometry.$F4.bgeo']) gplay must be in PATH, otherwise, specify a full path to it ($HFS/bin/gplay)

Untested, off the top of my head: node = hou.node('your_node') ptg = node.parmTemplateGroup() for i, file_path in enumerate(paths): pt = hou.StringParmTemplate('file%d' % i, 'File %d' %i, 1, file_path) ptg.addParmTemplate(pt) node.setParmTemplate(ptg) Or you could multi-parm block: hou.FolderParmTemplate( ... folder_type=MultiparmBlock)

Unfortunately, this is not possible at this moment. It could be quite useful, there were a few times when I wished this feature existed.

The menu script gets evaluated every time and so if you have an inconsistency between users/machines, you have to deal with it at the script level. There are also two types of menu: a string type menu and an ordered menu. I believe if you set it to a string type it will preserve its value.

Here's a simpler way: QPushButton.setCheckable(True) QPushButton.isCheked()

Hi, Yes, the ui module contains UI related stuff and is not available in Hython. You have few other options: 1. Use OpenGL ROP (probably the best option) http://www.sidefx.com/docs/houdini/nodes/out/opengl.html 2. Call Hscript http://www.sidefx.com/docs/houdini/commands/viewwrite.html Cheers

CMake generates this .proto file at build time. This recently introduced feature allows you (optionally) decouple parameter interface code from the main code. Again, it's not required to do it that way, unless you have special intentions like supporting compiled blocks feature for example or adding a "verb" (see docs) to your plugin. Now, if you absolutely necessary to use SCons, AND you have a code which uses this new paradigm (like SOP_Star.C) take a look at CMakeLists.txt file, you'll see houdini_generate_proto_headers function, which lives in toolkit/cmake/HoudiniConfig.cmake file. Implement it in your SCons script if you want. Cheers.

Using eventCallback is not the right way, the right way would be submitting a bug report since your code is totally fine and should work.

geo = hou.pwd().geometry() for f in random_file_list: geo.loadFromFile(f)

If you're talking about the procedural shader, it should be available within the SHOP context (or the new material context?). Try the SOP version for start. Compile the plugin. The latest compiled version available by the link above is for H16.0. Put the file in here: ~/Library/Preferences/houdini/X.X/dso/ Open the Terminal (http://www.sidefx.com/docs/houdini/basics/config_env.html) Set env variable HOUDINI_DSO_ERROR=2 and run Houdini. If there is a problem with loading the plugin you'll get the message printed out. Cheers.

It's pretty uncommon task to create a node inside thousands of other nodes. The issue easily might be nothing to do with your Python code or HDA itself but simply the Houdini bottleneck. What I would try: Profile your code with cProfile. This might give you an idea what takes time. Performance monitor doesn't help you in this case. You might be querying some Houdini parameter or geometry which makes Houdini cook it. Run your script in Hython instead. Try to do this in Hscript, although it's very unlikely you see any difference. Ask SideFx for support if you have a commercial license. Go crazy and write it in HDK

Vice versa. You attach the debugger to a running process. But as I said before, Houdini is not a process you want Python debugger attach to. Python interpreter is running inside Houdini process so the only option you have for real debugging is using a remote debugger. Maybe someone here could share if they have such experience, I haven't been able to set it up in Houdini.

Debugging and communicating with an application via a port is completely different things. You can do a socket to socket communication in Houdini via openport command or use Houdini's hrpyc Python server. For debugging, since you're running PyDev you should be able to use PyDev remote python debugger. I've had a few attempts to make it work but no luck.
