Houdini Main Changelogs

Houdini 5.1.112 Very minor compatibility change. The frac() function in VEX behaves slightly differently for fractional values very close to zero now. In general, this will improve behaviour of the frac() function, but may cause slightly different shading (usually fixing bad shading). Fri. May 10, 2002
Houdini 5.1.112 Changed the behaviour of the VEX frac() function very slightly. Fri. May 10, 2002
Houdini 5.1.112 Fixed a bug referencing depth maps in VEX or mantra3. Fri. May 10, 2002
Houdini 5.1.109 Displaying a user-friendly error message when installing a SERVER key when a SERVER key is already installed. Fri. May 10, 2002
Houdini 5.1.108 The update pattern for COPs tile cooking has been modified to increase multithreaded performance by approx. 8%, and this brings the speedup factor to 1.95x (up from 1.86x) for 2 CPUs (theoretical max is 2x). Thu. May 9, 2002
Houdini 5.1.108 The camera object OpenGL fog color parameter was changed so that it properly reflects that the parameter is a color. However, this will change the channel names associated with the fog color and break any existing animations which use animated OpenGL fog colors. Thu. May 9, 2002
Houdini 5.1.108 The channel names for the camera OpenGL fog color were changed to reflect that the parameter is actually a color. Thu. May 9, 2002
Houdini 5.1.107 There is new environment control variable, HOUDINI_DISABLE_UNSAFE_VEX, which can be used to disable certain "unsafe" VEX optimizations. Please see help for the variable for more information. Wed. May 8, 2002
Houdini 5.1.107 Right-clicking and choosing a renderer on the render button will now always fire-off a renderer, regardless of whether or not the new renderer chosen was the same as the previous one. Wed. May 8, 2002
Houdini 5.1.107 The render state now correctly restarts the render with the new view transform if viewtransform commands are issued in the textport. Wed. May 8, 2002
Houdini 5.1.107 Fixed bug where some changes to the view transform issued via the viewtransform command would not appear until the next time the user changed the view transform interactively. Wed. May 8, 2002
Houdini 5.1.106 The Ray SOP now can use point related local variables to adjust the tolerance, lift, scale, sample, and jitter on a per point basis. Tue. May 7, 2002
Houdini 5.1.106 Fixed bug in the render state where it would use the transform of the active (yellow) viewport when the re-render button was pressed, and not the transform of the viewport containing the render window. Tue. May 7, 2002
Houdini 5.1.106 The opinfo for SOPs now also lists any of the local variable mappings in the varmap attribute in a human readable fashion. Tue. May 7, 2002
Houdini 5.1.106 Fixed bug where dragging right after choosing the Edit operation would cause a crash. Tue. May 7, 2002
Houdini 5.1.106 Cleaned up drawing of open curves when in the wire over shaded modes. Tue. May 7, 2002
Houdini 5.1.106 The "Reverse Normals" menu now appears at the top of the viewport for the Mirror operation. Tue. May 7, 2002
Houdini 5.1.106 Using closed Quad Strip path types in PolySplit on a path that contained a non-quad would create a whole in the geometry where the last quad and non-quad would meet. We now insert a point in the last non-quad so that the geometry remains connected. If this particular circumstance applies to your models, the point counts/numbers may be affected by this change. Tue. May 7, 2002

Houdini 5.1.105 Fixed bug where it was impossible to snap to a polygonal face. Mon. May 6, 2002
Houdini 5.1.105 Index (ie. string) attributes now properly inherit when birthing particles from source geometry. Mon. May 6, 2002
Houdini 5.1.105 The "Show Custom Toolbars" option is now 'on' by default. Mon. May 6, 2002
Houdini 5.1.105 The render button had its help tag updated and it now has hotkey support. Mon. May 6, 2002
Houdini 5.1.101 Fixed bug in mouse interaction for the Peak and Edit Capture Weight handles which could cause the manipulator to accelerate depending on the view orientation. Thu. May 2, 2002
Houdini 5.1.101 There was a bug in mantra when exporting values from displacement shaders and then importing them into surface shaders in a special case. When the color cache filled up and caused re-shading to occur, the export/import mechanism would fail. This has been fixed. The symptom was that in very large scenes, there would be inconsistent (wrong) shading. Thu. May 2, 2002
