  1. Women Character Rigging

    Hey, Hi, I want to rig a realistic women character, Can someone tell me what is the way to rig a realistic character I'm planning to use a Advanced skeleton in maya, and including the blendshapes can also be helpful? or else painting my own weights will give the better result? ThankU.
  2. python folder creating

    Hi, I'm trying to make folder structure from python... there is a renaming problem I'm facing... How do we can make "vnc_001.......vnc_015", please check the image attached, I strongly required only 3 numbers at the end...
  3. I just did a Python script to create a sphere only with nulls. Actually can be done any shape you want. Here the video with the HIP file included: I know, it's a completely useless and silly project, but was fun to do. Any comment will be welcomed, Oscar
  4. normalize in vex and vop

    Hi, sorry about the silly question, I'm a beginner. NORMALIZE in vops, what it is used for, I saw many times in tutorials people using, but, nobody explaining about it... what it differs from the clamp node?
  5. Hello folks, so, i have a bunch of houdini file with a top node at OBJ level, all file have the same structure and are in the same folder I would like to cook the TOP node from external, Python or another TOP graph. I tried in a background script to access with hou.node('/obj/topnet').parm('cookbutton').pressButton(), but it seems that doesn't cook anything Any idea ? Thanks in advance
  6. Hi Houdini friends, I'm having a pretty weird issue right now and was wondering if this is something that someone else has encountered before: When I call a function as a callback to some button on an HDA/ shelf script, the result is different from when I directly call it in the python shell of an opened Houdini session / directly in a hython shell. More specifically, when called as a callback, it hangs; while when called from hython it went through as expected; The function involves some general wrapping code, that execute some houdini specific code, and it seems that any call from the hou module would hang when ran as callback. Does anyone have similar issues before / knows more about what might be different when something is executed as parm callback vs. directly from hython? Thanks soooooo much in advance!
  7. Hi, I'm playing around with limiting transform handles on nulls to act as a rigging control surface. I found on these forums a cool hscript snippet that allows this: clamp(cubic(),min,max). Does anyone know the python equivalent? The python clamp doesn't seem to accept a cubic() as a parameter. Also, does anyone know of another method of allowing for manual transform handle input that feeds into an expression? (HScript or Python). I can't wrap my head around why cubic() works! Cheers Dan
  8. Hey ODFORCE, Does PyCharm integrate with Houdini well? (Auto-completion, external debugging, unit testing?) Just curious. I did find some blog posts on VS Code set up, but I was curious about Houdini and PyCharm specifically. There was an issue with PySide from an earlier post..? (I'm fairly new to IDE set up, so forgive me if it's obvious) There are plugins for Nuke and Maya for PyCharm. Nothing for Houdini though.
  9. i am creating a point in between 2 points and i want to transfer all the attributes to this new point, is there a way to find all the attributes that are in a point? like a list/array ["Cd", "P", "N"...] thanks =)
  10. Hi, Is there a chance for example to get a picked position of a connection item ( where the pointer is picked its line ) ? I would place a node where it's picked.. I think the paste tool does similar when you pick a position at the Network Editor before paste. THX! G

  13. Hi, In a Filecache node I would like to add an other Rendering button after the factory default button. Can it be somehow ? G
  14. Descriptive Parameter to Node

    Hi, I found a very useful thing in docs but seems like not working for me unfortunately. Can anyone help ? I tried to add a descriptive parm to a node ( the same as a digital asset has ): node.setUserData("descriptiveparm", "parm") THX! G
  15. Hi, In Houdini Python (or hscript ) can we simply extract a given subnet content ? THX! G
  16. Hi, Can scripting can solve a node refreshing ( script run when the node exist ) in a specific time intervall. I mean for example a progress note is refreshed. I found some advanced usage of Network Editor with event but the timer event was not given by examples. Did anyone know use it ? THX! G
  17. Hi, Does Houdini give the possibility to add a progress bar to a user defined property page? Does it need Pyside? If needed a panel can be mixed with PySide elements too ? If anyone has idea, it's welcome ! THX! G
  18. Hi, Can anyone knows how to get a node object ( or parent node ) which parameters a parameter pane shows ? Thanks, G

  20. Hi, I would call a python subprocess (ffmpeg) which creates mov file from jpeg sequence from flipbooks. In Windows 7 it works well but in Windows 10 it makes Houdini Freeze. I tested it with older version of ffmpegs but none. Any idea, experiance of someone ? THX! G
  21. The Artist's Guide to Technical Direction in Houdini - Volume 0: Hscript Back in 2005 I got my start as an intern at Side Effects Software Inc. Over the past decade of using Houdini, I've worked around the world in the film (Starz Animation, Dr. D, Digital Domain) and games (The Coalition, BioWare, EA Motive) industries. In this time, I've had the pleasure of working with many artists who were new to Houdini and sharing some of the insight I've gained. While most people are pretty excited to get their hands on the flashier parts of the software such as FLIP and Pyro, I think that Houdini's greatest strength comes from it's sheer flexibility. And that flexibility is something that only opens up the deeper you delve into how things work. What I like most about Houdini is discovering new ways of doing things. One complaint I've heard time and again, is that after following a tutorial, new artists are often left with something that looks pretty but with little understanding of how anything actually works. I'm always hearing complaints about how steep the learning curve is with Houdini. I'm seeking to help fix that with 7 hours of new training material that focus specifically on HScript scripting in Houdini. This course I've designed for artists who are either lacking a technical background, or who may have experience in other packages but want to understand Houdini better. We'll avoid creating pretty things in this series. Instead, I want to keep a sharp focus on how things work. That means learning about procedural networks, variables and attributes, functions, and for-each loops. Most importantly, I address how to self-learn Houdini. My hope is that this course will build a solid foundation for you to get the most of any future training you pursue and help you to understand how to get the most out of your Houdini networks. If you'd like to become more adept at scripting in Houdini, please consider signing up for my course: https://mixtrn.com/course/the-artists-guide-to-technical-direction-in-houdini-hscript/ Have a Great Day!
  22. Array Function VEX

    Hi there, I'm playing around with creating some custom VEX functions and came across something a bit odd that I just can't seem to get working. If I want to create a custom function that returns an array, say a vector array I will need to declare the return type at the beginning, according to the docs the following should work // A function which returns an array of vectors vector[] rgb_array() { ... }; However if I run this in a wrangle I get a syntax error on line1. Is this a bug? Or am I declaring my function type incorrectly? Thanks in advance m
  23. Hey guys, I was wondering if anybody is familiar with using the hou.node.setDeleteScript() method. In the docs, the language arg is set to Python: setDeleteScript(script_text, language=hou.scriptLanguage.Python) But when running the following code, I get an error n = hou.node('/obj/geo1') cmd = 'x = 5; print x' n.setDeleteScript(cmd) OperationFailed: The attempted operation failed. Python is not yet supported in deletion scripts. Just passing an empty string gives the same error. When trying to set the language flag to Hscript with n.setDeleteScript('setenv x = "hello"', language=hou.scriptLanguage.Hscript) It raises another error TypeError: setDeleteScript() got an unexpected keyword argument 'language' Is there something I'm missing? I would normally create an HDA and use the built in 'On Deleted' call and run my code there, but for this particular case I'm unable to use an HDA. I was able to find this function all the way back in the Houdini 12 docs. Is it still not usable? Thanks!
