  1. Hello,

    I am currently trying to blend 2 fbx in chopnet context using the fbx reader.

    The general idea is to create automatic preroll blending restPose to Animation.

    My problem is when I blend the fbx (from rest to animation) whithout same numbers of channels the "simpleblend" node doesn`t  work.

    I would like to kwon if it's possible to compare to clip in order to delete the unused channels.


    Thanks for your time.

    Mathieu N.


    best regards






  2. Hi evryone,

    I start working on a rat crowd sequence.

    Evrything works well.

    My only problem is when I build my rat agent I have this difference between my fbx in hello and the baked agent.

    If somebody have an answer.

    I try changing the deform skin parameters.

  3. Hello evryone,

    I started using hq sim and hq render.

    I am wondering if I can rendering a rop geometrie inside a HDA?

    I don`t think I can`t because It seems logical that my rop geometrie are lock. 



    The other question is when you use a geometrie node inside a ropnet and you connect it to a hq sim and it s doesn`t seem to work as well.

    this is the log:

    The Houdini environment has been initialized.
    Traceback (most recent call last):
      File "/prod/prod2/Projets/2000/hqueue/shared/houdini_distros/hfs.linux-x86_64/houdini/scripts/hqueue/hq_run_sim_without_slices.py", line 4, in <module>
      File "/prod/softprod/apps/houdini/", line 1864, in callFunctionWithHQParms
        return function(**kwargs)
      File "/prod/softprod/apps/houdini/", line 1575, in runSimulationWithoutSlices
        alf_prog_parm = rop.parm("alfprogress")
    AttributeError: 'NoneType' object has no attribute 'parm'



    looks strage to me.


    thanks anyway.

  4. Thanks for you reply.

    But it s still doesn`t work for me.

    Just to be clear, I want to change the $JOB inside my scene with using the 123.py and 456.py.

    With this method I can change the context of any shots with reloading houdini.

    And just to be clear, I need $JOB for HQUEUE server because without a $HIP or $JOB it doesn`t work.

    I gonna continue to find a good solution for this problem.

    thanks again for your reply.




  5. Hi Evryone,

    I am currently building a Houdini pipeline in order to link it to shotgun.

    Everything work well and pretty easily.

    but there is a but.

    I am setting the env var JOB with the command set or setenv it`s the same.

    Each time I re-open the hip file my job env is not set correctly. Houdini keep the older JOB variables.

    And if I do the same manip into the UI in the aliases and variables it`s work well.


    I do not understand why.

    Many there is a logic.

    If anyone know please tell me.









  6. Hello.

    Not sure you can store a global var just for an hda.

    Maybe what you can do is to set a var with the command set or setenv:


    setenv -l MYVAR = tutu


    setenv -l MYVAR = tutu


    hou.hscript("setenv MYVAR = tutut")


    you can create this var every time you create you node and destroy it when you delete the node.

    I dont know if it s a good answer.


    tel me.
