Houdini Main Changelogs

Houdini 5.1.59 Motion blurred displacement mapping has been sped up in mantra. Results may be very subtly different, but no more incorrect than in previous versions. Thu. March 21, 2002
Houdini 5.1.59 Fixed a bug in operator nested menus where clicking to bring up a nested menu and dragging the mouse over the entries would actually close the menu when the mouse passed from the buttonstrip containing the popup menu to another one in the underlying menu. Thu. March 21, 2002
Houdini 5.1.58 Added the morient function that constructs a matrix to orient to an arbitrary axis system. Wed. March 20, 2002
Houdini 5.1.58 Dragging off of a radio buttonstrip in a menu will now revert the value back to the previous one rather than sticking with the last one passed over. Wed. March 20, 2002
Houdini 5.1.58 Fixed SI_FlexMenuButton and UI_Flex to work properly with sticky menus. The first time the menus were brought up and an entry selected without releasing the mouse button, it would simply treat it as if the user clicked and released to bring up the menu. This should no longer be the case. This was visible on the RMB menu on the construction plane button and the pane dynamic path widgets. Wed. March 20, 2002
Houdini 5.1.58 Source POP will no longer give an incorrect warning that the distribution attribute does not exist when it clearly does. Wed. March 20, 2002
Houdini 5.1.57 The chgadd command no longer allows channel group names with non-alphanumeric characters. Tue. March 19, 2002
Houdini 5.1.57 The chgadd command no longer allows channel group names with non-alphanumeric characters. Tue. March 19, 2002
Houdini 5.1.57
  • Error messages are now reported if a backup save fails.
  • if HOUDINI_BACKUP_DIR is set to a directory that doesn't exist it gets created recursively (i.e. mkdir -p) rather than the mkdir rules.
Tue. March 19, 2002
Houdini 5.1.57 explodematrix added as an expression function. This allows you to extract the euler channel data associated with a transform matrix to drive Houdini channels. Tue. March 19, 2002
Houdini 5.1.57 Removed channel related entries from the UVEdit handle menu. Tue. March 19, 2002
Houdini 5.1.57 The Ctrl+RMB menu in MPlay now contains toggles to show or hide all the various UI bars. Tue. March 19, 2002
Houdini 5.1.57 MPlay now handles lock files more intelligently.
  • The hostname of the machine MPlay is launched on is appended to the lock file (.mplay.host) so that the same user with a remote shared home directory can run MPlay on different machines without a conflict.
  • COP Flipbooking uses a different lock file (.flipbook.host) so that rendering and flipbooking can be done simultaneously without interfering with one another.
  • Stale lock files are properly detected and overriden (MPlay will continue to load instead of exitting). Valid lock files still halt MPlay.
Tue. March 19, 2002
Houdini 5.1.57 New environment variable HOUDINI_BACKUP_DIR allows users to specify the directory used by "Numbered Backup" save option to store old hip files. Tue. March 19, 2002
Houdini 5.1.56 The AttribCreate Operation now takes a group parameter. If a new attribute is being created, entities not in the group get the default value. Otherwise, they pass through unchanged. This allows the AttribCreate to be an attribute editor for manipulating user generated attributes. Mon. March 18, 2002
Houdini 5.1.56 New icons for Look At, Parent and Follow Path states. Mon. March 18, 2002
Houdini 5.1.56 You can drag to reorder the parameters in the Properties::Parameters lister. You can also do this to reorder inputs listed for an OP. Mon. March 18, 2002
Houdini 5.1.53 MPlay now has a profile manager, which allows customization of its different uses (default, render, flipbook, tools, full, minimal). The profiles are stored in the preference file mplay.profiles, and contain layout options, some display options, and default startup command line options. Fri. March 15, 2002
Houdini 5.1.53 MPlay now has a Save Preview function which saves out the images in the current viewport with the current brightness controls, background image and crop region. Previews are limited to 8 bit RGB. Fri. March 15, 2002
Houdini 5.1.53 Fixed problem where the UVProject handle would sometimes not show the orthographic projection guide. Fri. March 15, 2002
Houdini 5.1.52 Disconnecting the chain root of an IK bone chain now properly recooks the InverseKin CHOP. Thu. March 14, 2002
Houdini 5.1.52 Deleting keys of locked channel segments are no longer allowed. Note that deletion of an entire locked channel is still allowed. Thu. March 14, 2002
Houdini 5.1.52 Values for custom panels are now properly saved and loaded from the hip file. Unfortunately, the interests to execute scripts and watch operator parameter changes are not "wired-up" until a panel's UI is actually built. In addition, slider and input field initial values are currently ignored. Hitting cancel in the interactive UI builder is no longer as prohibitive as it was previously with large custom panels. Thu. March 14, 2002
Houdini 5.1.51 The chls command now lists channels in ascending instead of descending order.

Similarly, the Fetch CHOP now fetches channels in ascending instead of descending order. In this way, it is now consistent with the Export CHOP and if it fetched from parameters which did not have channels.

Wed. March 13, 2002
Houdini 5.1.50 Fixed bug where the bonefixchops command would not properly adjust affected InverseKin CHOPs if the bone chain was in an object subnet. Note that the bonefixchops command is in the delete script of bone objects by default and thus affects regular deletion of bones in IK bone chains. Tue. March 12, 2002
