Houdini Main Changelogs

Houdini 4.9.589 This change was made in 4.9.446 but not documented. In the LSystem SOP, various improvements were made:
  • The point width attribute is multiplied by the thickness value of the lsystem, so will match the diameters of the tube generation.

  • Generations over 127 produce the correct generation number.
  • When point attributes are generated, we create more than just the width attribute:
    • segs ($SEGS), an integer point attribute for the number of segments (rows) tubes leaving that point should have.
    • div ($DIV), an integer point attribute for the number of divisions (columns) tubes leaving that point should have.
    • lage ($LAGE), the age of the point in the lsystem.
    • arc ($ARC), the arc length from that point to the root of the lsystem.
    • up ($UP[XYZ), the up vector for the tubes birthed at that point.
    • gen ($GEN), the integer generation of that point.
  • When point attributes are created, the system's points are automatically sorted by generation. This means point numbers will match from generation to generation, allowing motion blur, etc.

Houdini 4.9.588 The HOUDINI_OUTLINEFONT_PATH now includes $WINDIR\Fonts. Wed. January 9, 2002
Houdini 4.9.588 The gfont application has a new -q option for suppressing output messages. Wed. January 9, 2002
Houdini 4.9.588 The internal names for the "Mantra 3" and "VEX Mantra" operators have been changed to omantra/mantra from mantra/vmantra. When loading .hip files, we check the version of the saved hip file and will automatically convert the operator types. However, existing scripts cannot be checked in such a fashion and are thus not forward compatible to H4.9.588. For example

        hscript -> opadd mantra
        hscript -> opadd vmantra

should now be

        hscript -> opadd omantra
        hscript -> opadd mantra

Houdini 4.9.588 The Blend and Sequence Blend SOPs now blend alpha attributes if Do Colours is on. There is no work around to this. Wed. January 9, 2002
Houdini 4.9.588 The blend and sequence blend Operations now blend alpha attributes if Blend Colours is turned on. Wed. January 9, 2002
Houdini 4.9.588 In specifying path names for objects, trailing slashes are ignored. Thus, cd /obj/logo/ is as valid as /obj/logo. Wed. January 9, 2002
Houdini 4.9.588 The Extrude SOP no longer unholes all of the incoming geometry. Instead, it only unholes that geometry which will be extruded. One can restore the old behaviour by prefixing a Hole SOP with Unhole turned on. Wed. January 9, 2002
Houdini 4.9.588 The Hole SOP with "Unhole" chosen now preserves group information. There is no work around to this. Wed. January 9, 2002
Houdini 4.9.588 A ".hip" extension will automatically be added to the filename if the user doesn't specify it. Wed. January 9, 2002
Houdini 4.9.588 The Extrude Operation no longer unholes its entire incoming geometry. Instead it just unholes the subset to be extruded. Wed. January 9, 2002
Houdini 4.9.588 Unholing now preserves group information. Wed. January 9, 2002
Houdini 4.9.588 Fixing bugs where clicking on a handle to enable or disable it didn't create an undo block. Wed. January 9, 2002
Houdini 4.9.588 Doing a single carve on a torus which cuts it once in the U and V direction will unwrap the torus like one would expect. Wed. January 9, 2002
Houdini 4.9.588 Adding a section to the HDK documentation on how to debug HDK code on linux. Wed. January 9, 2002
Houdini 4.9.586 Fixed bug in Dissolve SOP that would sometimes cause a core dump. Tue. January 8, 2002
Houdini 4.9.586 Fixing bugs a hard-locked sop would sometimes generate the error "not enough sources specified" if it had no inputs connected to it. Tue. January 8, 2002
Houdini 4.9.586 Adding help for the sop-level select state. Tue. January 8, 2002
Houdini 4.9.586 Adding a check-box for the "select from all objects" option to selector's menus. "select from all objects" can still be turned on and off by right-clicking on the "see one/see all objects" icon. Tue. January 8, 2002
Houdini 4.9.586 A polygonal quadrilateral grid of dimmensions 1xN no longer generates an error. Instead, it generates by rows as one would expect. Tue. January 8, 2002
Houdini 4.9.586 Degenerate primitives will now convert in the Convert SOP. This may cause some new primitives to convert that didn't before. There is no workaround to this. Tue. January 8, 2002
Houdini 4.9.586 Degenerate primitives, such as zero volume spheres, now convert. This also includes 1xN meshes, which now convert to polygons in the expected fashion even if surface type isn't set properly. Tue. January 8, 2002
Houdini 4.9.586 Toggling vertex selections with vertex grips on now works correctly with region selections. Previously it would toggle once for the actual vertex, and once for the grip, resulting in no change. Tue. January 8, 2002
Houdini 4.9.586 We now truncate long paths in the file history menu. Tue. January 8, 2002
Houdini 4.9.586 Fixed problem with toggling multiple points in point selections in the UV viewport when using vertex UVs where the point would be toggled for every vertex referencing it which was selected. Tue. January 8, 2002
