Houdini Main Changelogs

Houdini 4.9.581 The order of operations of the power operator (^) has changed. It now will bind tighter than * or /. This means 2*3^2 will now evaluate to 18 instead of 36. There is no workaround. Wed. January 2, 2002
Houdini 4.9.581 The power operator (^) in expressions now binds higher than * or /. This means the expression 2*3^2 will evaluate to 18, not 36. Wed. January 2, 2002
Houdini 4.9.569 There are now three levels of details for OP tiles. The smallest is now just a box with no flag buttons, so you can move tiles without tripping flags at highest zoom. Tiles also now zoom properly so actually get smaller when you zoom out. As a result, the layout code is now zoom invariant. Furthermore, you likely don't need to work as zoomed out as before to get the same node densities. Thu. December 20, 2001
Houdini 4.9.569 In the network overview, tiles appear in their native colour (the colour they are set to with the override colour option). Any flags colours, if present, are shown by quarter size squares inside the network tile. Thu. December 20, 2001
Houdini 4.9.569 The network overview ('o' in network view) and color pane ('c' in network view) now draw on top of any tiles, not underneath. Thu. December 20, 2001
Houdini 4.9.569 The Group SOP again allows the typing of non-alphanumerics into the name field. However, it will generate a redflag error if the resolved group name contains anything other than letters, numbers, and underscores. Thu. December 20, 2001
Houdini 4.9.569 The Extrude SOP no longer negates the point normals if they don't align with the primitive normal. This means extrusions always go in the direction of the point normals if present. The work around is to negate any point normal which has the opposite direction of a face normal. Thu. December 20, 2001
Houdini 4.9.569 The Extrude Operation now uses the point normals as is, rather than reversing them to align with the primitive normal. Thu. December 20, 2001
Houdini 4.9.568 Expressions like "linear" and "spline" will now evaluate to their incoming/outgoing values outside their segment range rather than continue to change. Wed. December 19, 2001
Houdini 4.9.568 The multi-host output driver has been removed from the default distribution. It is now available only as a plug-in (via proto-install). Wed. December 19, 2001
Houdini 4.9.568 After homing to a point, the view pan function should move as quickly as it would if you had zoomed to that point. Wed. December 19, 2001
Houdini 4.9.568 The Channel SOP will find the CHOP references, which it has been unable to do since version 554. Wed. December 19, 2001
Houdini 4.9.568 Ascii .geo files with extra precision in floating parameters should now load on NT. Wed. December 19, 2001
Houdini 4.9.567 The printf/sprintf functions in VEX now handle format specifications with leading 0's in the width field. For example:

        int ival = 32;
        mapname = sprintf("path%04.rat", ival);

will assign "path0032.rat" to the mapname variable.

Tue. December 18, 2001
Houdini 4.9.567 The search path for dialog scripts for OP macros (and the renderer plus button) has been changes so than instead of including all dialog scripts found, users are required to include the base level files (as with other table files). This allows users to replace or remove system default dialog scripts with their own versions (which was not possible before without modifying the Houdini distribution). Tue. December 18, 2001
Houdini 4.9.567 Fixed bug in PolyExtrude when extruding two orthogonal faces and symmetry is turned off. Tue. December 18, 2001
Houdini 4.9.567 When switching the direction of playback in realtime mode using the arrow keys, the playbar should no longer jump to the beginning or end of animation. Tue. December 18, 2001
Houdini 4.9.566 The "Animatable Parameters" dialog now has a Ctrl+RMB that lets you see only the parameters that have channels, or group all those parms at the top of the dialog.

If this is too late for docs, please remember it for H5.1.

Mon. December 17, 2001
Houdini 4.9.566 The Clip SOP and the Divide::Bricker SOP will produce different vertex orders than in earlier versions. There is no workaround. Mon. December 17, 2001
Houdini 4.9.566 The Clip and Bricker SOPs now produce more consistent vertex orders. They are less likely to change the implied orientation of polygons. Mon. December 17, 2001
Houdini 4.9.566 In Edit::Preferences::Tiles there is now an option to disable the automatic setting of the highlight flag on new SOPs added in the viewport. Mon. December 17, 2001
Houdini 4.9.564 Capture tubes render in shaded modes (without wires) again. Sat. December 15, 2001
Houdini 4.9.564 Having a non-transparent material or shop assigned to the primitives will no longer cause the alpha attribute to be ignored if transparency is toggled on. Sat. December 15, 2001
Houdini 4.9.563 When merging hip files, we no longer modify any of the animation settings such as current frame, frame range, etc of the hip file to be merged. Fri. December 14, 2001
Houdini 4.9.563 The Bones operation now has an option to parent chain roots to IK affectors. Fri. December 14, 2001
