Houdini Main Changelogs

Houdini 4.9.541 Adding preferences for whether or not secure selection should be on by default at the sop and object levels. Thu. November 22, 2001
Houdini 4.9.541 Transform state should no longer core dump in TOPs and should be functional. Thu. November 22, 2001
Houdini 4.9.541 When using the Set Keyframe option in object-specific handle for Bone objects, it now only sets keyframes on channels that are specifc to the handle type. eg. Set Keyframe while right-clicking on the capture region handle will only set keyframes on the cregion parameters. Thu. November 22, 2001
Houdini 4.9.541 PLEASE READ AND COMMENT ON THE FOLLOWING CHANGE!

In previous builds of Houdini 5 the Transform SOP had defaults $GCX, $GCY, and $GCZ for its pivot. These defaults were set in the sop's creation script to avoid breaking custom user scripts. Now these defaults are hard-coded, so scripts may be at risk.

First, in case the reason for the new defaults is not clear, let me provide an example. Suppose you have an object, say a box, located at (0, 0, 4) in space. Now you apply a transform sop with the intent of rotating that box. You change the Y rotate parameter to 90 degrees.

  • With the OLD pivot defaults (0, 0, 0), the box rotates 90 degrees
around the world Y-axis, ending up at a new position (4, 0, 0).
  • With the NEW pivot defaults ($GCX, $GCY, $GCZ), the box rotates 90
degrees around its own center, so it's position is still (0, 0, 4). It is expected that most users involved in everyday modeling will want the new more intuitive behaviour.

The new defaults should not cause a problem interacively. You can still set the pivot parameter to (0, 0, 0) if you want, and even make that the permanent default.

Existing scripts, however, may pose a problem. These may have been written assuming a (0, 0, 0) pivot. "opscript" commands that do not set the pivot explicitly will have to be changed to set the pivot to (0, 0, 0) if that is the behaviour the script requires.

Please comment on whether this change is a significant inconvenience, and if the benefits of more intuitive modeling transformations justify such inconvenience.

Houdini 4.9.540 When deleting a group from the channel list using the pull down menu, we now correctly delete the associated group as opposed to the currently selected group which may not be the same thing. Wed. November 21, 2001
Houdini 4.9.540 The chadd hscript command's -f and -t options now work. Wed. November 21, 2001
Houdini 4.9.540 Fixed crash in Blend Object when using the Constrain option with a Reset Frame that is greater than your current frame. Wed. November 21, 2001
Houdini 4.9.540 The Ray SOP Minimum function now works for NURBS & Bezier surfaces (broke in 4.9.525) It also will work properly with polygons and meshes (never worked). Wed. November 21, 2001
Houdini 4.9.540 In the Save View to Camera window, the "Use Camera Pivot" now behaves as one would expect. Some related redraw issues are also addressed. The "Use Camera Pivot" is now default to prevent accidental changes to the camera pivot when setting up camera paths. Wed. November 21, 2001
Houdini 4.9.539 The Add SOP now has the Delete Geometry but Keep points at the top of its point list so it is visibile. The Remove Unused Points is likewise highlighted.

The Delete SOP now has a Keep Points option that allows you to delete primitives but keep the points in an intuitive fashion.

Tue. November 20, 2001
Houdini 4.9.539 TOPs dropped from the viewport now connect intuitively and layuot nicely as well. Tue. November 20, 2001
Houdini 4.9.539 Hopefully fixed some annoying bugs with tight scrollbars (such as on the toolbars) from not laying out properly. Tue. November 20, 2001
Houdini 4.9.539 Bound SOP no longer core dumps and actually works correctly when "Keep Inputs" and "Divisions" are both toggled on. Tue. November 20, 2001
Houdini 4.9.538 Putting a little cross at the "hotspot" of the hand cursor. This way you can till what geometry is beneath the cursor when you right-click on it. Mon. November 19, 2001
Houdini 4.9.535 Adding keyframes should work again after resizing the channel graph editor window. Fri. November 16, 2001
Houdini 4.9.535 Fixed crashing bug with brush symmetries on non-polygonal objects. Fri. November 16, 2001
Houdini 4.9.535 The Edit Capture Weights spreadsheet has been fixed to match the speed of the slider handles in the viewport. Fri. November 16, 2001
Houdini 4.9.534 Problems with the CapturePaint brush ghosting the old geometry after a frame change resets the deform orientation should be fixed. Thu. November 15, 2001
Houdini 4.9.534 Pasting operators (especially objects) are a lot faster now. Thu. November 15, 2001
Houdini 4.9.534 Undo and redo of operator creation, deletion, pasting should work now. Thu. November 15, 2001
Houdini 4.9.534 Fixed bug with not being able to render the default scene using mantra 5. Thu. November 15, 2001
Houdini 4.9.534 Brushes on NURBs, Bezier, and Mesh surfaces should have their normals oriented the right way.

Brushes in general should be less flighty with their normal directions.

Thu. November 15, 2001
Houdini 4.9.534 Fixed a bug with the SOP viewer where changing it to a network pane and deleting the sops and then switching back to a viewer would result in a crash. Thu. November 15, 2001
Houdini 4.9.533 Assigned a volatile hotkey ('b') to the Transform state at the Object level. The hotkey appears in the title of the Ctrl+RMB menu of the Transform state. There's no easy way to change the hotkey other than by opening up the hotkey dialog and searching for "volatile", then editing the appropriate hotkey entry.

Since the Transform state is also the default favourite state at the Object level, you can use 's' to enter it in non-volatile mode. And if that's not enough, you can Alt+Ctrl+Shift on the Transform icon on the viewport's toolbar and assign a unique key specifically to the Transform state.

The SOP-level Transform state is not affected by this change.

Houdini 4.9.533 Default orientation in the Grid SOP is now ZX. Wed. November 14, 2001
