Houdini Main Changelogs

Houdini 6.0.197 Fixing a core dump in exit that was introduced in the last version or two. Fri. January 31, 2003
Houdini 6.0.196 Added a "hscriptinstance" procedural which will instance the results of executing a single SOP in hscript to each point in the geometry. The SOP is opparmed with all the attributes of the point. Thu. January 30, 2003
Houdini 6.0.196 There's a new parameter in light sources to control the style of attenuation. There are currently three settings. Thu. January 30, 2003
Houdini 6.0.196 The ASAD light shader now has options to do physically accurate attenuation (i.e. 1/(r*r) falloff). This option should be used when computing photon maps. Thu. January 30, 2003
Houdini 6.0.196 The Highlight Object Selection option has been moved from the Viewer Controls menu to the Settings menu. Thu. January 30, 2003
Houdini 6.0.196 There's a new expression function (frac()) which returns the fractional component of the floating point value. This is similar to the VEX function of the same name. Thu. January 30, 2003
Houdini 6.0.196 The Blur COP now has separate parameters for X and Y, and by default Y is off (linked to X). Old hip files with different values for X and Y will need to have their Y sizes updated.

The default blur kernel is now Gaussian.

Thu. January 30, 2003
Houdini 6.0.196 Sprite procedural now supports motion blur and can copy attributes from the source point to the new sprite, allowing the overriding of shader parameters with these attributes. Thu. January 30, 2003
Houdini 6.0.196 When the last channel segment is a constant() expression, it's out value is now used to extend the channel as opposed to its in value. Wed. January 29, 2003
Houdini 6.0.196 When the last channel segment is a constant() expression, it's out value is now used to extend the channel as opposed to is in value. Wed. January 29, 2003
Houdini 6.0.195 Fixed the pop select state to actually work, and updated it to support the new selection types introduced in version 5.0. Wed. January 29, 2003
Houdini 6.0.195 Added a "sprite" procedural which correctly interprets the attributes set by the sprite pop and instances a sprite at each particle. It is important to note that the shop references are indirect, and the output driver must have "Shop References" set to "Declare all SHOPs". Wed. January 29, 2003
Houdini 6.0.195 Added cycle/cyclet expression functions which behave similar to repeat/repeatt except that they will cumulatively repeat the motion in a cyclical fashion. They can also repeat motion in a backwards manner if the first parameter is greater than the second. Wed. January 29, 2003
Houdini 6.0.195 As Tab is now used for command and path completion in the Textport, you can no longer type raw tabs into the textport. If \t does not work, one can still force a tab by cutting and pasting text containing a tab. Wed. January 29, 2003
Houdini 6.0.195 Adding menu bars to each pane and changing the look of the panes slightly. Wed. January 29, 2003
Houdini 6.0.194 The textport now does tab completion for cd, opcf, and opcd, where it completes to the longest matching path when one hits tab.

The network reference gadgets (such as those in object merge sop) also now respect tab completion when building a path relative to the root.

Tue. January 28, 2003
Houdini 6.0.194 The Pose Handle's rotate mode now uses rotate handles instead of vector handles. They are sized to be one third of the average bone length in the chain. Tue. January 28, 2003
Houdini 6.0.194 In the Scope Channels... dialog, there is now an option to scope inputs as well. Tue. January 28, 2003
Houdini 6.0.194 The Highlight Object Selection option is now turned on by default when Houdini is loaded. Please try it out and see how you like it. Tue. January 28, 2003
Houdini 6.0.194 The brush SOPs now respect the visibility state of primitives. If a primitive has been made invisible with the visibility SOP, it will not be brushable with the brush SOPs. Tue. January 28, 2003
Houdini 6.0.194 The viewport has a new style of panning. This is changed from the Settings::Main Preferences::3D Viewports::Panning Method option.

Previously in Houdini, panning the viewport will keep the pivot to where the last home occurred. This meant when you panned and zoomed into a subsection of your geometry, rotating would orbit the center of the geometry rather than the center of your interest. This is known as "Maintain Viewport Pivot when Panning".

The new method will move the pivot so it stays at the center of your viewport. This allows one to change the point of interest without having to re-frame on a subregion. This is known as "Move Pivot when Panning".

The current default is the new method.

Tue. January 28, 2003
Houdini 6.0.194 Fixed bug where the viewport render button would get confused if the current renderer is renamed or deleted. Tue. January 28, 2003
Houdini 6.0.193 The graph mode of the channel editor now has new options in the right-mouse menu for framing the selected keys and smoothing the selected slopes. The default hotkeys are 'f' and '9' respectively.

The menu was also corrected to show the previously hidden item to home all graphs (the hotkey 'h').

Mon. January 27, 2003
Houdini 6.0.193 The Capture/CaptureProximity SOPs now have the ability to layer on their weights on top of pre-existing capture weights. You can also control the blending factor.

The object-level Capture Geometry state has also been updated to make use of this new feature. You can also now change the capture type without reselecting.

Mon. January 27, 2003
Houdini 6.0.193 The CaptureMirror SOP has been changed to work better with seams. When a point lies exactly on the mirror plane, the corresponding point is determined to be the point with the same position that is not in the mirror group. As a result, if the geometry has a seam along the mirror plane, and one half of the geometry is selected as the mirror group, the expected result occurs along the mirror plane. This is different from 5.5 where about half the time mirroring would not occur. Mon. January 27, 2003
