Houdini Main Changelogs

Houdini 4.9.342 Persistent PIs are now stored in the hip file. There are new commands for creating, modifying, and grouping persistent PIs. There is also a new pane type that provides a UI for modifying persistent PIs.

The IK end affector handle now has the pivot handle at the end of the bone for doing IK, plus it draws a second handle that looks like a bone. Grabbing this handle does FK on the chosen bone. The Move Single Bone option has been removed from this handle. As well, Shift-clicking on a handle will toggle the Locked state of that joint. Finally, for a given IK end affector PI, only a single handle is "current". The current handle has the full pivot handle drawn. Non-current handles just show the small box from the center of the pivot. For locked joints, the box is drawn shaded. For unlocked joints, the box is drawn in wireframe.

Houdini 4.9.342 The Joint handle for bones can now also delete joints. The handle will now always clean up the transforms of modified objects. Tue. April 24, 2001
Houdini 4.9.338 Miscellaneous fixes to illuminance() loops in VEX fog shaders when ray-tracing. Doing illuminance() loops in fog shaders should produce correct results when ray-tracing now. Fri. April 20, 2001
Houdini 4.9.337 When there were many objects being rendered in vmantra (typically in the thousands -- usually due to particle instancing), vmantra would waste a large amount of time in object setup. This setup time has been significantly reduced. In a sample case of 4550 particle instances, render times went from 4:15 to 0:49. Thu. April 19, 2001
Houdini 4.9.337 New hotkeys have been added for the object/sop viewport layouts. In 4.0, they were 1,2,3,etc. They are now Ctrl+1,Ctrl+2,Ctrl+3,etc. Thu. April 19, 2001
Houdini 4.9.336 The Object Copy and Mirror States both now have options to specify the destination CHOP network to place copied InverseKin CHOPs.

The Bone Create State now cleans the transform of all its created objects. New options here include:

  • Specifying the name of the CHOP network to place InverseKin CHOPs
  • Ability to create twist affector objects for IK bone chains
  • Option to automatically set the Keep Position when Parenting flag on created affectors and chain roots
  • Options to coloir chain roots and affectors the same as their bone
FK End affectors are now also created with an orientation that matches their bones.
Wed. April 18, 2001
Houdini 4.9.336 Split viewports should now refresh properly when display options are changed with "Apply Changes to All Split Views" toggled on. Wed. April 18, 2001
Houdini 4.9.335 Bone and Object Mirror States have been collapsed into a single Object Mirror State. The Bone Mirror State has been renamed to be the Object Mirror State. The Mirror State now provides a preview of where the mirrored objects will appear. Hotkeys have been added to the Mirror State to switch between the mirror planes. Mirroring now works with object subnetworks. Twist affector objects (used by InverseKin CHOPs) are now also copied or mirrored. The option to not copy end affectors have been removed. Fixed mirroring bug when end affectors were already in the same hiearchy as the bone to be mirrored. The Mirror State no longer creates mirror Null objects (it uses the pre-transform instead).

The bone twist handle now only shows its front part to the viewer so that it is easier for the user to determine its orientation.

Fixed bug that caused Houdini to crash when trying to convert old bone objects that have no channels via the boneconvert command.

In the Bone Create State, to go back one bone while drawing, it is now the delete key, not the backspace key. When drawing new bone chains, the first bone's local y axis is now always aligned to be perpendicular to the construction plane.

The Bone Joint handle now works with any type of bone chain as opposed to only No Kinematics bone chains.

Cameras and the IK Handle CHOP now work with cleaned transform objects.

Ambient lighting bugs have been fixed when only happened to show up with bone objects.

mplay now starts up on NT without crashing.

Fixed crash that happened if you tried to load a hip file with a desktop that did not exist.

Tue. April 17, 2001
Houdini 4.9.335 Implemented network navigation commands (like in the modeller) for traversing the COP network in the viewport. Tue. April 17, 2001
Houdini 4.9.335 New Expand COP, which does matte expansion and contraction. Tue. April 17, 2001
Houdini 4.9.335 Implemented the Rotospline COP and its associated handles. Tue. April 17, 2001
Houdini 4.9.5 Started 4.9 Version file. Wed. April 4, 2001
Houdini 4.9.5 When dragging tiles, press the ALT key to avoid drag-n-drop and just simply move. (Cursor restores to original state). This allows one to move the tiles off the pane to hidden areas. Currently you must press ALT *after* starting the move, since ALT-clicking on a tile will 'jump down' into the network once released. This will be resolved at a later date.

Clicking on 'Jump to Export Chop' in floating parameter window coredump fixed.

Mechanism added to allow specific behaviour when drag-n-dropping to specific op parameters.
