Houdini Main Changelogs

Houdini 6.2.20 When choosing "Create Type From..." from the popup RMB menu for a subnet operator, when the Type Properties dialog appears, Houdini automatically saves the new operator type as if the Apply button was pressed. Mon. October 20, 2003
Houdini 6.2.20 Undoing a rename operation on a locked subnet operator type could cause the expressions of the nodes inside the subnet to be erased. This problem is now fixed. Mon. October 20, 2003
Houdini 6.2.20 Fixed a problem with channel referencing a parameter of a node that is not cooked (such as an object that isn't displayed). Suppose geo1, geo2, and geo3 are all objects. geo2 is not displayed. geo2/tx is 'ch("../geo1/tx")' and geo3/tx is 'ch("../geo2/tx")'. Changing geo1/tx would not move geo3 because geo2 would not cook and so would not propagate the parameter change. This problem is now fixed. Mon. October 20, 2003
Houdini 6.2.20 When a parameter uses a channel reference with th "!!ch()!!" format, the parameter is marked with a green dot in the parameter dialog. This makes it easy to detect parameters using this sort of channel reference. Mon. October 20, 2003
Houdini 6.2.20 The Sticky objects now have a reasonable selector which prompts for object to stick to. They thing prompt to move the sticky by clicking on the object.

Infinite recursion of the sticky space transforms is now detected and properly errored.

Mon. October 20, 2003
Houdini 6.2.20 Transform spaces will no longer be declared in RIB/IFD streams for null objects if the null object isn't displayed or the null object doesn't match the visible objects parameter. Mon. October 20, 2003
Houdini 6.2.20 Transform spaces are output for null objects if and only if the null object is "displayed". That is, if the display flag of the null object is turned off, or the null object doesn't match the visible objects pattern, a transform space will not be declared in RIB or IFD streams. Mon. October 20, 2003
Houdini 6.2.20 Running the chgadd command from hscript will no longer output an error message regarding undo blocks. Mon. October 20, 2003
Houdini 6.2.20 Fixed bug that could cause Houdini to crash if the user hits Alt-N to create a new scene and chooses an entry from the toolbar history. Mon. October 20, 2003
Houdini 6.2.17 Made Rotospline a little more friendly. Handle selection can now be done by box selecting with the Left button, instead of requiring Alt+Left. Clearing the selection can be done by Left clicking on nothing. Fri. October 17, 2003
Houdini 6.2.17 Fixed a potential problem with RMB dragging in the Image viewer to pan; if the user paused long enough, it would attempt to open a menu, but since COPs doesn't have a RMB menu, this could corrupt the state. This was most noticable in the view state, where the image would often fly off the screen (requiring a home). Fri. October 17, 2003
Houdini 6.2.17 The Brush sops should be less jumpy when used with 3/4 views of models that have a large scale factor. Fri. October 17, 2003
Houdini 6.2.17 Fixed bug where PolySplit could cause a crash if the user has some hidden geometry (through the Visibility SOP) and reselects and selects geometry very quickly. Fri. October 17, 2003
Houdini 6.2.17 Open curves and polygons can now be lit when the viewport is in shaded mode. To enable this, there is a new toggle in the display options in the Wireframe page called "Shade Open Curves In Shaded Modes". In addition, geometry objects have a new parameter in the Misc page, called "Shade Open Curves In Viewport" which must also be turned on to shade the open curves in that particular object. The reason for this granularity is because when using this new shading mode, we must disable display lists, and the goal is to do this for as few objects as possible. A new option "-c" was added to the viewdisplay command to allow setting the display option on the command line. Fri. October 17, 2003
Houdini 6.2.17 The expand COP now expands luminance when working with Color or vector planes by default. This is about 3x faster than expanding on individual color components. The old behaviour can still be accessed by turning off the "Use Luminance" toggle. Fri. October 17, 2003
Houdini 6.2.17 Fixed a bug where the Mirror SOP could cause a crash if mirroring quadrics and not keeping the original geometry. Fri. October 17, 2003
Houdini 6.2.17 There was a subtle bug in computation of derivatives in some extreme cases when ray-tracing in mantra. This intermittent bug might have caused NAN's or even possibly crashes in ray-traced images (including global illumination). Most notably, there was a specific bad case when ray-tracing against open polygons. Thu. October 16, 2003
Houdini 6.2.16 Added a display preference, "Fast Pixel Aspect Ratio Display", which is on by default. When on, a simple horizontal pixel scale is applied in hardware to any image with pixel aspect ratio that isn't 1. When off, a slower software box filter scale is used, which eliminates the artifacts that are present in the hardware scale.

This is only noticable for fractional aspect ratios - integer aspects such as 2 (or 1/2, 1/3) work just as well in Fast mode.

This also applies to the Halo viewer.

Houdini 6.2.16 channel group widget caches count of number of channels starting to make things faster Thu. October 16, 2003
Houdini 6.2.16 -w <width> and -h <height> now work for loading files. Previously they only work for specifying the size of files read in by stdin. All files loaded on the command line will by loaded at width x height, regardless of their natural size. Thu. October 16, 2003
Houdini 6.2.16 Fixed a problem with loading images from the file browser in mplay. They would load up as black frames. Thu. October 16, 2003
Houdini 6.2.16 Added "Set Current Values to Defaults" menu entry to Presets menu. It behaves as the corresponding entry in the parm menu, but does so for the entire set of parameters. Thu. October 16, 2003
Houdini 6.2.15 Fixed a couple of problems with the copinput VOP.
  • adding the component input caused the other inputs to shift, and existing VOPnets have all their inputs connected by index, which caused X,Y and Frame to be connected incorrectly, thus breaking backwards compatibility with VOPs.

  • A strcmp in the #if signature line was formed incorrectly, and broke the signatures for several types (resulting in monochrome (red channel) output only).
Wed. October 15, 2003
Houdini 6.2.15 A problem with ray-nonplanar quad intersection has been fixed. The Ray SOP should be more stable with quad meshes. The Brush tools should be less likely to paint through the geometry when painting on quadrilateral meshes. And the Inflate SOP should be less likely to miss points when working with quadrilateral meshes. These problems showed up at the edges of non-planar quads. Wed. October 15, 2003
Houdini 6.2.14 Houdini now properly coredumps when HOUDINI_COREDUMP is set but HOUDINI_UI_COREDUMP is not on Unix systems. This enables stack trace generation while still attempting to save the .hip file. Tue. October 14, 2003
