  1. Houdini 14 Wishlist

    1. Move to Qt framework 2. python 2.7 3. More python integration 4. More powerfull viewport
  2. I want to store files in my asset to access them via opdef: For textures(pictures) it work well? but not for models (obj, abc, ...) How to solve this. I simple want to store my models in asset
  3. Is it possible to export materials from maya to houdini with alembic via custom attributes. In my maya-script i have: 1. List of materials - ['blinn1', 'lambert1'] 2. List off materials ID for each face - [0,0,1,0,1,1] With this script i can split any mesh in maya. But I need to have in houdini geometry from alembic and two prim groups (for this simple example) --> 'blinn1' = 0, 1, 3; 'lambert1' = 2, 4, 5 At now i can add custom attr to shape setAttr "pCubeShape1.matID" -type "Int32Array" 0 0 1 0 1 1[/CODE] and replicate groups in houdini. But maybe it is other methods to normal export materials facesets from maya to houdini
  4. Alembic ROP problem

    1. I had 3 animated fractured objects. If export all objects with Alembic ROP it works well. 2. But i need export ObjectMerge SOP where this objects are stored. In this situation export fails and Alembic ROP give me warning: What i need to do for export ObjectMerge SOP? scene - http://dl.dropbox.co...ured_export.hip
  5. AlembicSOP bug

    It is problem with AlembicSOP. I think it is bug. 1. All meshes with hard edges exported from Maya = in AlembicSOP have valid normals 2. All meshes with soft edges exported from Maya = in AlembicSOP have valid normals 3. Meshes with hard edges + soft meshes exported from Maya = in AlembicSOP soft meshes have not normal attributes, but hard are OK In other words If i export multiply meshes from maya where it is hard and soft meshes at once - in houdini soft meshes have not normal attributes If all meshes are hard or all meshes are soft - normals valid How to fix, if it possible ? Sory for bad english
  6. Hi, guys. I have serious problem with alembic. 1. It is AlembicArchive object node with heavy geometry 2. If I press button "Build or Update Hierarchy" it updates very fast 3. But if I want update in my python code - it is very slow It behaves equally if I call function, for example: node=hou.node('/obj/alembicarchive1'); node.hdaModule().BuildHierarchyRoot(node)[/CODE] or press button in my code: [CODE]hou.node('/obj/alembicarchive1').parm('buildHierarchy').pressButton()[/CODE] It updates very slowly. I think it is problem with hom implementation or _alembic_hom_extension module that AlembicArchive used. How do you think???
  7. AlembicArchive very slow update from python code

    Guys, can any one replicate same problem? I wand to send bugreport. My conf: gentoo linux ~amd64, houdini-12.1.230 x64 gcc-4.4
  8. AlembicArchive very slow update from python code

    Yes. with hscript it works well, but not from python. And its not only from Python shell, but also from scripts. As i understand, any function in hdaModule called outside from asset, works slow. Sometimes i need call python functions of asset from different places - pythonShell \ functions in other sub assets etc.
  9. AlembicArchive very slow update from python code

    Simple example. This is my asset: If i press butoon Test - it works well. But if I write something like: hou.node('/obj/myasset').parm('Test').pressButton() - it works very slow. Why ? What I`m doing wrong?
  10. AlembicArchive very slow update from python code

    All functions called out from node.hdaModule() \ nodebuttons work ~10 times slower (
  11. AlembicArchive very slow update from python code

    Im doing something wrong, because its not only with AlembicArtchive. All functions manually pressed works very faster than calls in code Pleaze help me.
  12. pane geometry

    Is it possible to get pane geometry - x,y,width,height ?
  13. Alembic ROP problem

    Yes, it really not correctly exports Mesh-type geometry with topology changed in time. But strangeness that at a normal method (not ObjectMerge SOP) everything is normal Any ideas?
  14. Alembic ROP problem

    Strange. If i set sphere type as PolygonMesh (not Mesh) it works well )
  15. Alembic ROP problem

    Also, as you can see, animation stoped when any object contact witth ground and fractured. In other words the first contact spoils an alembic. Edit: With 2 objects it is different situations when everything normally...
  16. Alembic ROP problem

    Do you mean ObjectMergeSOP? At now i tried, and it also fails out of subnetwork (/obj). Can you post your scene?
  17. AttribStringEdit

    I use AttrribStringEdit to change attribute value. I dont understand how to change my sting from: /foo/bar[/CODE] to [CODE]bar[/CODE]
  18. AttribStringEdit

    Very thanx! You saved my precious time.
  19. In windows after use file node(like alembic, file...) i cannot delete file, even if node deleted and file not in use. How to delete files? In other words - How to release file and delete it without reload houdini? My asset need to delete file after destroy itself. In linux works well, but not in windows
  20. Canntot delete files after use in nodes. Need restart houdini

    I'm sorry, I was wrong. In fact, it does not work only with alembiс. Why ?
  21. delete asset in on creation event

    How to delete asset from it self. For example, i want to delete it in On Creation event script of asset
  22. delete asset in on creation event

    Thanx - but i dont need button manually deletion. I need asset that auto delete it self when need
  23. delete asset in on creation event

    and i want this condition inside asset
  24. delete asset in on creation event

    i need to use a condition where it is possible to cancel asset creation
  25. Som HOM questions

    1. Simple piece of code: try: hou.node('/obj/').destroy() except: pass In Houdini and Hython it works well. But in remote functions ( from Maya and other python interpreters ) with hrpyc it does return error and exception dont work. 2. How to know that node is deletable? It is hou.Node.isLocked() method, but it works only for HDA. What about other non-deletable nodes?
