  1. I have added interpreter " C:\Program Files\Side Effects Software\Houdini 16.0.705\python27\python2.7.exe ". Added paths "C:\Program Files\Side Effects Software\Houdini 16.0.705\houdini\python2.7libs " to pycharm. added "C:\Program Files\Side Effects Software\Houdini 16.0.705\houdini\python2.7libs" to system's PATH variable of win10 but when i type in "from PySide2 import QtWidgets " i get the error message in PyCharm : Unresolved reference 'PySide2'
  2. Hello, in Houdini 15 I was using hou.ui.selectFile() dialog to get user's input and I would process it further in python. I used the same function to let user select files or folders, based on the needs of a tool. Now I updated to 16 and the function does not seem to enable user to select a folder, it works only with selecting a file. Does anybody know if there is a way to select a folder in 16? I want to batch process files in a directory and I would like to use file browser dialog to let user set it. In worst case I could use hou.ui.readInput(), and to ask user to enter a path there, but this is super user-unfriendly Thanks, Juraj
  3. UI Dialog Help

    I imagine this is very simple but I find building ui's with python a bit tricky (compared, for example, to Maya which is very straight forward). I want to create a simple window (or dialog or ui) with several text fields, float fields, int fields etc. I have it working with hou.ui.readMultiInput, but you don't have much control in terms of layout/styling or what data types are allowed/expected. What are the best functions for this kind of thing?
  4. Hi everyone, I'm trying to have my Python Module in my HDA place another node right below my asset on creation. So my OnCreation script runs my python module from disk, which has the following code: pos = first_node.position() second_pos = (pos[0], pos[1] - 2) second_node.setPosition(second_pos) This does nothing. The second node is always created near (0, 0) in the network editor. But if i run those lines in the Python shell in Houdini, it works just fine. So that tells me that the OnCreated scripts don't wait for the HDA to actually be placed into the scene before running, despite what the docs say (a problem I've run into before). My solution to this was to use hdefereval to wait to run the code until the event loop was idle. This shows promises of working, but I'm running into issues now. The code I'm trying is: pos = first_node.position() second_pos = (pos[0], pos[1] - 2) hdefereval.executeDeferred("second_node.setPosition(second_pos)") but the problem here is that when it goes to execute the code, the variables no longer exist, and the code fails because "Name 'second_node' is not defined". But I use a custom 123.py script every day that has the exact line hdefereval.executeDeferred("hou.hscript(code)") where "code" is a pre-defined variable, and hdefereval has no problem using that variable when it goes to execute. So I'm not really sure what the problem is here. What is the best way to move a node using Python? (and if you know how to get my hdefereval call to work, that'd be even better!) Thanks, ~Chris
  5. Hi. Guys. I got a huge work to do, there is a fbx file export form max,when i import it to houdini, it include too much parameters on Geo interface form max. So i want delete it all since it was useless. I make a sketch show what i want to do. I just want to remove the ss parameter form interface, not just delete the keyframes or expression. If there was something like hou.parm().destory() modules can do this. Thanks.
  6. Hello, what I would like to do is very simple, just for an exercise. I would like to run Houdini from a Python script using the hou module. What I am trying to get working is something like: import sys import subprocess sys.path.append('/opt/hfs15.0.244.16/houdini/python2.7libs') import hou hou.hipFile.load(file_name='/home/ramon/hello.hipnc') sf_geo = hou.node('/obj').createNode('geo') But I get no UI. I could do subprocess.Popen(['houdinifx', '/path/to/hipfile.hpnc']) but it creates deatached from the python script. Maybe should I create it first through shell (subprocess.Popen) and then load it using hou.hipFile? and start playing with it inside the python script? I would like to have a self-contained example. Just a python file that the user just runs like python script.py no more. Thanks and sorry for the stupid question. EDIT: I think I found out what I was looking for... haha... now i can compile vfls using Popen subprocesses and import them afterwards and doing everything in a self-contained file. cool. import sys import subprocess sys.path.append('/opt/hfs15.0.244.16/houdini/python2.7libs') import hou hou.hipFile.save(file_name='/home/ramon/hello.hipnc') hou.hipFile.load(file_name='/home/ramon/hello.hipnc') sf_geo = hou.node('/obj').createNode('geo') hou.hipFile.save(file_name='/home/ramon/hello.hipnc') subprocess.Popen(['houdinifx', '/home/ramon/hello.hipnc'])
  7. Hi I want to import .abc cache containing a maya camera into houdini scene, but I can't seem to find the approriate hscript or hou functions. I mean I can do it manually by file --> import--> alembic scene. But How do I automate this in python script ? there is some animation from frame 1-100 in the .abc file. I tried to compile alembic on windows 8.1 because I want to try the SOP_AlembicIn included in the code, I got lots of error when trying to do so. For geometries I know I can create a geo node, and go inside create a alembic node to import .abc file.I think convert this to hscript is pretty straightforward. But for camera .abc file, this doesn't work, while file --> import--> alembic scene seems working, is there a way to code this camera import in python ? or is there another way ? or someone has compiled this for windows ? Thanks.
  8. Hi everybody, Can anybody point me to a way of getting text highlighting of the hou module while using emacs as an external text editor? Thank you!!!
