Houdini Main Changelogs
|Houdini 4.9.387|| VMantra handles compositing of the Af variable differently now. Previously, the compositing was flawed in that opaque/partially opaque surfaces which had the Af variable set to 0 (i.e. a matte surface) would not composite properly in the rendering process. Now, the Of variable controls how opaque the Af variable is. That is, with a surface shader:
the surface shaded will occlude 50% of the background color and also 50% of the background alpha. Previously, the Af of the background would have shown through 100%.

|Houdini 4.9.387||If a scale handle is oriented to the world axes, it will now draw less of itself in an ortho viewport. This will help expose the parts of the handle that make sense for that orthographic projection. The handle will be easier to pick and manipulate and will cover less screen space.||Fri. June 8, 2001|
|Houdini 4.9.387||Fixed bug introduced in 4.9 where using the middle-mouse button in the table mode of the graph editor would disable all subsequent scoping of channels.||Fri. June 8, 2001|
|Houdini 4.9.387||Changed the pomattach command so that instead of simply taking a list of op parameter names, it now takes a set of parameter pairs of the form: "opparm:piparm". This new format makes this command more readable, and much much easier to write.||Fri. June 8, 2001|
|Houdini 4.9.387||Added help for the persistent manipulator commands.||Fri. June 8, 2001|
|Houdini 4.9.386|| The joint handle in the Bones state now has an option to orient the current bone's X axis with the normal of the floor.
The joint handle in the Bones state now has a new handle type, the Spider handle that allows you to precisely position a joint along the axis of its connecting bones (as well as along the normal to the connected joints).
|Thu. June 7, 2001|
|Houdini 4.9.386||Just a note about the new "undoctrl" command. This command will speed up the execution of scripts with the caveat that script cannot be undone. WARNING: This can turn off the undo mechanism inside Houdini...||Thu. June 7, 2001|
|Houdini 4.9.385||The 'r', 'e', 't' hotkeys that change the type of any handle derived from a transform handle now also act as toggles. Thus, if the translate jack is visible, 't' will toggle the jack off; pressing 'e' will make the handle reappear as a scale handle; and so on.||Wed. June 6, 2001|
|Houdini 4.9.384||PolyKnit state and SOP can now do meta-edges. A meta edge is the shortest path connecting two points. So a user can select two points that are not adjacent, and the SOP will find the path connecting them and knit appropriately. The state was modified to show the meta edge correctly.||Tue. June 5, 2001|
|Houdini 4.9.384||Deleting the cop node being used for the background image in a viewport will no longer core Houdini.||Tue. June 5, 2001|
|Houdini 4.9.384||The IK End Affector handle now works on bone chains that are controlled by an IK Chop with "Inverse Kinematics" solver type (i.e. true "IK" chains).||Tue. June 5, 2001|
|Houdini 4.9.383||The objpretransform command is no longer generated with the opscript command if the pretransform is not modified from its default identity value. This improves compatibility of the opscript command with Houdini 4.x when the pretransform is not used.||Mon. June 4, 2001|
|Houdini 4.9.383|| The Bones state's Shift+LMB interaction has been improved. It no longer overrides your currently selected chain parent. The new behaviour is as follows:
||Mon. June 4, 2001|
|Houdini 4.9.383|| The Bones state now creates bones that are oriented with the floor in the viewport that the bone was completed. The X axis of the bone is aligned to be parallel with the normal of the floor. If while in the perspective view and the construction plane is off, then the viewing plane is used.
Chain roots are now created aligned with the world axes. KNOWN BUG: This feature breaks IK w/Constraints. This will be fixed before Houdini 5 ships.
|Mon. June 4, 2001|
|Houdini 4.9.380||The buttons to the left of the viewport for turning handles on and off now let you right click on them to see the same popup menu available when right clicking on the handle itself.||Fri. June 1, 2001|
|Houdini 4.9.380||Fixed bug where executing the "chrmkey" command without specifying either the -t or -f option would cause Houdini to crash.||Fri. June 1, 2001|
|Houdini 4.9.378||Fixed some bugs in the handling of twist on FK bones. Added an option to the IK End Affector Handle to specify whether or not the handle should maintain joint locks when the current time changes. Previously this capability was always on.||Wed. May 30, 2001|
|Houdini 4.9.378|| Fixed core dumper when a collision pop (without the "Add Hit Diffuse Color Attribute" or the "Add Hit Texture UV Attribute" option toggled on) cooks in a simulation which already has these attributes added by another collision pop.
NOTE: A collision pop will fill out these two attributes if they exist in the simulation, just like it does all such hit attributes. It does not need to have the add option for the attribute toggled on.
|Wed. May 30, 2001|
|Houdini 4.9.378||The new Houdini .pic format images can now be gzipped and read successfully by Houdini apps. When creating PRISMS .pic.Z files, gzip compression will now be used instead of using "compress" which uses a patented compression algorithm. Old .pic.Z files can still be read correctly.||Wed. May 30, 2001|
|Houdini 4.9.378|| There is now an environment variable which can be used to set the default color for missing texture maps:
% setenv HOUDINI_TEXTURE_DEFAULT_COLOR "red green blue alpha"
will cause missing texture maps to return the color specified when accessed in VEX.
|Wed. May 30, 2001|
|Houdini 4.9.378||The commands for creating the default scene in 123.cmd has been split into its own file, defaultscene.cmd. The file 123.cmd is loaded whenever Houdini starts up and from within 123.cmd, defaultscene.cmd is sourced.||Wed. May 30, 2001|
|Houdini 4.9.378|| Old change that should have been noted back in Houdini 4.9.337:
There is an option to specify the maximum memory usage for the undo
manager under the "Preferences..." menu option. It is set to 1000 Kb by default in Houdini 4.9. In Houdini 4.1, it was fixed at a size of 100 Kb.
|Wed. May 30, 2001|
|Houdini 4.9.377|| Miscellaneous fixes to 3d texture code:
||Tue. May 29, 2001|
|Houdini 4.9.376|| The Bones State's joint handle can now be switched to a rotate handle via the 'r' key or the right-click menu of the handle. This gives full control over the orientation of the bone.
Similarly, the default bone object handle has been updated to use the new bone rotate handle.
The orientation of the translate handle in the Bones State no longer loses its orientation when you tumble.
FK end affectors in the Bones State now align themselves to their associated bones when you move the position of a joint via the joint handles.
|Mon. May 28, 2001|
|Houdini 4.9.376||Tolerance sliders in SOPs, such as those for project, cookie, etc, are now logarithmic. This means that if you slide it one unit to the right, the number becomes ten times larger, and if you slide it one unit to the left, the number ten times smaller. This is more in line with the sort of changes one wants to make with tolerance values.||Mon. May 28, 2001|
