Houdini Main Changelogs

Houdini 6.0.70 The Object Merge SOP (object_merge) has a new set of parameter names. Files created with the old parameter names will be automatically forward converted when cooked in 6.0. Scripts refering to the names will have to update to the new ones:
  • obj# and sop# for the two components of the sop path are now hidden. If non-empty, they will trigger the autoconversion process.

  • xform is also no longer used, it is converted to the xformpath.
  • numobj is the number of entries in the dynamic UI, ie: the number of objects to merge.
  • enable# is whether each object path will be merged or not.
  • objpath# is the path to the object or sop to merge, either a relative path to this SOP, or a full path from root.
  • xformpath is the path of the object to use for the transform relation. If empty, no transform is done. If it points to a SOP, that SOP's object is used.

Houdini 6.0.70 The Object Merge SOP now uses the dynamic UI. This also means instead of the object/sop menu to select the object, a regular path dialog is given. This gives added flexibility allows simple drag and drop selections.

Old Object Merge SOPs should automatically convert into the new mode. Scripts which refer to the old parameters will have to be updated.

  • Fixed bug where reference input lines were never drawn in the active color
  • Fixed bug where the dotted lines would ignore the "thick lines" preference
  • We now draw the op names and the links with a drop shadow when a background image is being displayed so that they will be visible against both dark and light backgrounds.
Tue. September 24, 2002
Houdini 6.0.68 The Point SOP now has a Custom tab where you can specify explicitly an attribute to affect. The attribute will not be created (use the AttribCreate for that) but can be changed. Tue. September 24, 2002
Houdini 6.0.68 The grid parameters in the worksheet are now saved with the desktop. Tue. September 24, 2002
Houdini 6.0.67 Fixed a bug in IGES import that would sometimes cause a crash if the spline being imported isn't valid in Houdini (e.g. has too high an order). Mon. September 23, 2002
Houdini 6.0.67 The worksheet display options have grown to Network Editor Display Options. They now include display options for both the worksheet and the oplist viewers. The ctrl-right menus for worksheets and oplists are significantly smaller now. Mon. September 23, 2002
Houdini 6.0.64 The Transform SOP (xform) no longer has the Pivot about Group Centroid option. Old transform sops will be automatically converted to using the ($GCX, $GCY, $GCZ) expressions in its Pivot parameter the first time it cooks. Fri. September 20, 2002
Houdini 6.0.64 Fixed bug in the Capture/CaptureProximity SOPs that could crash if they encountered a bone more than once when traversing the object hierachy. For example, this situation could happen if bone1 outputs twice into a blend object and the blend object outputs into bone2. Fri. September 20, 2002
Houdini 6.0.64 The Add SOP now has dynamic UI. This means an arbitrary number of points, or an arbitrary number of primitive description lists can be specified. The default is still 25 and 6. Fri. September 20, 2002
Houdini 6.0.64 With the addition of dynamic UI, the Add SOP no longer supports the local variables $PT# as you can have an arbitrary number of added points, but not local variables.

The parameters "points" and "prims" have been added which govern the number of points or primitives to have in the UI.

The number of points and primitive fields now defaults to 1 rather than 25 and 6 respectively. Old files should generate the required number of parms automatically.

Fri. September 20, 2002
Houdini 6.0.64 Fixing a problem where the '/etc/init.d/sesinetd stop' script would attempt to shut down the license server on a different machine if hserver was using a different machine as the license server. Fri. September 20, 2002
Houdini 6.0.64 When manually placing background images in the viewport, a negative scale can now be entered to properly flip the image. Fri. September 20, 2002
Houdini 6.0.63 When running "opadd -n bone", the bone object now gets a default rotation order of ZYX instead of XYZ. This was a dangerous thing because all the character tools assume a ZYX rotation order. Thu. September 19, 2002
Houdini 6.0.63 The Global Animation Options dialog now has a button to snap all keys to integer frame boundaries. Note that this does the equivalent of "chround -a". Thu. September 19, 2002
Houdini 6.0.63 Under the main Dialogs menu, there is now an option to bring up the Channel Editor (if it is not up already). Thu. September 19, 2002
Houdini 6.0.63 There is a new 'choption' (channel option) hscript command that controls global animation options. This gives identical functionality to the Global Animation Options dialog of the playbar. See "help choption" for full usage. Thu. September 19, 2002
Houdini 6.0.63 There is a new "Apply" button in the Global Animation Options dialog (playbar plus button) that controls when the changed Start/End values get applied. This allows the animator to change the start/end values both at once without losting intermediate precision that may result from doing them one after another. Thu. September 19, 2002
Houdini 6.0.63 The following options from the the Channel Editor options dialog have been moved into the Global Animation Options dialog (plus button in playbar):
  • Initial Segment: Function
  • Added Segments: Auto Function, Split function, Auto slope, default slope
  • Hold Last Key
The Global Animation Options dialog now has the ability to save all the options as default so that they get loaded upon each new Houdini session. Note that all of these options will get saved along with the hip file.
Thu. September 19, 2002
Houdini 6.0.63 Having SOP nodes templated will no longer invalidate the display lists of other nodes as a result of the wire color not being properly maintained. Thu. September 19, 2002
Houdini 6.0.62 Fixed crash in the Save Texture Image option in SOP nodes. Wed. September 18, 2002
Houdini 6.0.61 A new command, "optype" has been added to hscript. This allows you to query the network type, table name, and optype, of op nodes. The optype command in the expression language has been expanded by the addition of an optypeinfo expression which allows the user to get these expanded parameters inside expressions. Tue. September 17, 2002
