Houdini Main Changelogs

Houdini 6.0.198 The op name highlight color for Animated Parameters is now a darker shade of green. Mon. February 3, 2003
Houdini 6.0.198 Added the vex SOP context function addvariablename(string aname; string vname). This will add the mapping for vname to point to aname, so in SOPs such as the Point sop, $vname will access the attribute. This allows one to emulate the behaviour of AttribCreate. Mon. February 3, 2003
Houdini 6.0.198 Light handles can now handle cone angles > 180 degrees. Mon. February 3, 2003
Houdini 6.0.198 New Light geometry will help to better visualize cone lights. Mon. February 3, 2003
Houdini 6.0.198 The Shader SOP now turns on indirect referencing of SHOPs by default. Mantra, RIB and .mi generation all handle the indirect references better now. Mon. February 3, 2003
Houdini 6.0.198 Added the AttribPromote SOP. This sop allows one to convert between detail, point, primitive, and vertex attributes, along with specifying how to convert, ie: max, min, average, root mean square, etc. Mon. February 3, 2003
Houdini 6.0.198 Fix bug where cone lights were not accurately displayed in the viewport. Mon. February 3, 2003
Houdini 6.0.198 Fix bug where PolyExtrude handle was being incorrectly clipped when in Local Mode. Mon. February 3, 2003
Houdini 6.0.198 Fix bug where guide geometry for the Fan Force object would go to infinity when the Fan Delta parameter is increased. Mon. February 3, 2003
Houdini 6.0.197 The AttribCopy SOP now allows you to copy detail attributes. Fri. January 31, 2003
Houdini 6.0.197 The geometry spreadsheet now allows you to view and edit detail attributes. Fri. January 31, 2003
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
