  1. using node.parm().clickButton() without UI

    hipFile='U:/projects/ttv/episodes/e408/work/sq010/sh070/Houdini' Version 1: print "before", print hou.hscript('echo $HIP') hou.hipFile.save(os.path.join(hipPath,"ttv_"+shotBaseName+"v001.hip")) print "after", print hou.hscript('echo $HIP') output: before ('U:/posterToolsBase/mayaScripts\n', '') after ('U:/projects/ttv/episodes/e408/work/sq010/sh070\n', '') Version 2: print "before", print hou.hscript('echo $HIP') pa=os.path.join(hipPath,"ttv_"+shotBaseName+"v001.hip") pa=pa.replace("\\","/") hou.hipFile.save(pa) print "after", print hou.hscript('echo $HIP') output: before ('U:/posterToolsBase/mayaScripts\n', '') after ('U:/projects/ttv/episodes/e408/work/sq010/sh070/Houdini\n', '') WTF???? Where is Houdini folder gone in version 1? in both versions .hip file is saved in correct location (in 'U:/projects/ttv/episodes/e408/work/sq010/sh070/Houdini' folder) But it works now :))
  2. using node.parm().clickButton() without UI

    No. just found that. It's weird combo of "\\" and "/" mixup between python and houdini internals. I wouldn't mind that some Hou.Error was raised, like "File not found" or something. For some reason while in python $HIP variable get wrong value. I save my houdini scene to r"U:\projects\ttv\episodes\e408\work\sq010\sh070\Houdini" but $HIP gets reseted to "u:/" After some experimentation, I found that houdini want to set $HIP to something like "U:projects tvepisodese408worksq010sh070Houdini" (notice space instead of \t - hou must interpret it as tab escape char :))) I think I'm on right track now. Thanks a lot for initial push :)))
  3. using node.parm().clickButton() without UI

    Hi Tomas, thanks for answer ... It's soooo wierd ... You are right, when I execute those commands in python shell they work as expected. But when I execute script in same shell it does nothing. This is part of script that is handling import into houdini ... tempTime = time.clock() print "Importing into Houdini ... ", m = hou.node("/obj").createNode("alembicarchive", ns[1:],run_init_scripts=True, load_contents=True, exact_type_name=False) # m.parm("fileName").set(os.path.normpath(os.path.join(abcPath, ns[1:] + '.abc'))) print "Node",m.name() m.parm("fileName").set("$HIP/../anim/sceneABCexport/"+ns[1:]+'.abc') print("Subnet Content before update: {}".format(m.children())) m.parm('buildHierarchy').pressButton() print("Subnet Content after update: {}".format(m.children())) # hou.hscript("opparm -c /obj/"+str(ns[1:])+" buildHierarchy") # m.hdaModule().BuildHierarchyRoot(m) # m.parm("buildHierarchy").pressButton() # m.parm("buildHierarchy").eval() # m.cook(force=True,frame_range=(1001,1001)) m.moveToGoodPosition() print "done. ("+str(time.clock() - tempTime)+" sec)" No error, no warning ... just nothing :((( (commented out are things that I've tried and didn't work) This is output ... Importing into Houdini ... Node ttv_prop_oldsafe_rig_mr_MASTER Subnet Content before update: () Subnet Content after update: () done. (0.00554966969401 sec) Superstrange. I'm digging into it but still have no idea what is wrong. Is there a chance that callbacks are executed in different thread and I have to wait (timer.sleep(100) or something) for .pressButton() to finish?? How I can find when it's done?
  4. I'm trying to python script maya->houdini transfer script via alembic. I've sorted out most of kinks, but there is one hurdle that's giving me a headache for days now ... I have to use alembicArchive because I need node tree. In script I create a alembicArchive node, set all params as desired and execute aNode.parm("buildHierarchy").pressButton() While I was testing this in houdini's python shell pane everything worked great. Once I left houdini UI and went to python I can't generate subtree. I need that because I need to assign shaders and some other things before I save a file. I tried to force cook node (aNode.cook(force=true)) but it didn't solve it. Any ideas how to force this node to rebuild hierarchy? thanks. edit: of course that i meant pressButton() method instead clickButton … lapsus. Also I found that I can call calback script on this button (item.hdamodule().BuildHierarchyRoot(item)) or do i via hscript's “opparm -c” but that also does not work without UI … so I'm still on square one. I know that there is a possibility to build alembic hierarchy myself, but I would like to avoid that if possible. tom.
