Houdini Main Changelogs

Houdini 6.0.21 Preliminary support for area light sources has been added to mantra. Mantra currently supports line, grid and disk lights. In the current implementation, the light shader will be called multiple times (based on the sample parameter passed in the light object). Thu. August 8, 2002
Houdini 6.0.21 Preliminary support for area lights has been added to Houdini. The light object now has parameters to control the shape, size and sampling controls for area light sources.

When rendering with MentalRay, the shapes defined are mapped as follows:

Line Light: A cylindrical light defined along the x axis. The length of the cylinder is specified by the area light size. The radius is 0.001 units.

Grid Light: A rectangular grid of the size specified. The grid is defined in the XY plane in the space of the light.

Disk Light: A disc light oriented in the XY plane. The radius is defined by the size specified.

Sphere Light: The radius of the sphere is defined by the area light size.

Cylinder Light: A tube with a length of 1 unit (in the x-axis of the light source) whose radius is defined by the area size parameter.

Note: All light sources may have scales applied to them on top of the area light size parameter.

Houdini 6.0.21 Fixed overlapping menu buttons in the operator lists (for input menu buttons). Thu. August 8, 2002
Houdini 6.0.19 Added Proxy file support to the File COP & File Still COP, so you can specify a different file for different resolutions. Tue. August 6, 2002
Houdini 6.0.15 Fixed bugs where the pop viewer was not aware of changes in the popnet when it was viewing the subnet. This was a problem since the pop viewer always cooks to the cook node in the popnet.

One seemingly unrelated symptom of this was the yellow reset button not properly working when viewing subnets.

Fri. August 2, 2002
Houdini 6.0.14 The proto_install program now has command line options to install packages.

The usage is:

        proto_install -i <install_path> -p <package>

where

<install_path> is the path to install eg. $HH or $HOME/houdini5.5 <package> is the package name with .inst extension

Examples:

        proto_install -i $HH -p SOP_PointMap.inst

This installs the pointmap sop into the main installation that will be available to all users.

proto_install -i $HOME/houdini5.5 -p CHOP_Puppet.inst

Houdini 6.0.14 Added help for the popview state. Thu. August 1, 2002
Houdini 6.0.14 Interactively adding pops in the viewport will now not set the cook flag on the new pop, unless the one we just branched off from was the cook pop. Thu. August 1, 2002
Houdini 6.0.13 Fixed bug in linking the OGL diffuse colour for shops when there was no specular colour or it did not occur first in the parameter list. Wed. July 31, 2002
Houdini 6.0.13 Made the POP viewer display subnets in the dynamic path gadget as it used to do way back in v3. Wed. July 31, 2002
Houdini 6.0.12 There were problems in computing motion blur when generating render scripts for vmantra, mantra3 and mental ray. This could cause bad behaviour (like no motion blur, or backward motion blur). Tue. July 30, 2002
Houdini 6.0.12 All default desktops now default to the rounded connection style. Tue. July 30, 2002
Houdini 6.0.11 Removed the "Animatable Parameters..." option from handles that are not animatable. Mon. July 29, 2002
Houdini 6.0.11 Updated the help for the Copy SOP. Mon. July 29, 2002
Houdini 6.0.11 For illuminance() loops which specified an unusual angle other than PI, 0, the sense of illumination was reversed. This has been fixed, and illumance() loops like:

        illuminance(P, nf, radians(45))

will work properly now.

Mon. July 29, 2002
Houdini 6.0.11 To edit the name of an op in the worksheet, you have to click on the name where it does not overlap another tile. Clicking on the tile will now take precedence. Mon. July 29, 2002
Houdini 6.0.4 Auto increment of number in node names now respects leading zeros. Thus cutting and pasting test_01 will result in test_02 and not test_2. Mon. July 22, 2002
Houdini 6.0.4 Added extra help on the MMB to pops. It lists the local variables. Mon. July 22, 2002
Houdini 6.0.2 Added undo manager which allows the user to examine the undo/redo stacks, and perform multiple undo/redo operations at once. Sat. July 20, 2002
Houdini 6.0.1 Added environment variable HOUDINI55_COMPATIBILITY to deal with issues in Houdini 6 that are no longer compatible with Houdini 5.5. Fri. July 19, 2002
Houdini 6.0.1 Fixed bug in giges that would cause it to crash if we fail to cut a certain bspline surface. Fri. July 19, 2002
Houdini 6.0.1 Houdini 6 begins today. Enjoy! Fri. July 19, 2002
Houdini 17.0.? As the title says: Bumped 5.5.0 to 6.0.0 Fri. July 19, 2002
Houdini 5.5.57 Fixed bug where rotation discontinuities could sometimes occur when using the Composite CHOP. Thu. July 18, 2002
Houdini 5.5.57 The VEX shadowmap() function behaves differently in shading contexts now. It will produce better results, but different than prior versions of mantra. Thu. July 18, 2002
