Houdini Main Changelogs

Fri. September 10, 2021
19.5.4

Fixed an issue where defining custom node info templates could cause the TOPs node info window to break.

Fri. September 10, 2021
19.5.4

Converted Karma-specific API schemas for extending lights, cameras, and geometry primitives to be "codeless" schemas. This means they have no C++ or python APIs, but it also means that they can be used with other USD libraries without having to compile any code.

Fri. September 10, 2021
19.5.4

Added a preference to control whether or not the viewport is allowed to load and display payloads that have been explicitly excluded from loading by a Configure Stage LOP.

Fri. September 10, 2021
19.5.4

Added the ability to use python to construct "post-layers" on a LOP Network. These are USD layers that are stronger than any LOP-authored layers, and which are composed onto the viewport stage, and the LOP authored stage viewed in the scene graph tree and output by the USD and USD Render ROPs.

Fri. September 10, 2021
19.5.3

Fixed include/accessibility issues with the C++ Public API.

Thu. September 9, 2021
19.5.3

The Volume Trail SOP is now verbified.

Thu. September 9, 2021
19.5.3

Color parameters can now be set from the MaxScript API.

Thu. September 9, 2021
19.5.3

Updated the delete operation in Curve-2.0 SOP to work with rounded corners, and fixed a couple bugs with the delete operation that could result in degenerate curves.

Thu. September 9, 2021
19.5.3

Added render region support for render delegates in the LOPs 3D viewport, by Shift+LMB dragging while in the 2D mode of the View state. This only affects delegates that use the AOV interface.

Thu. September 9, 2021
19.5.3

When DOPs interpolates geometry, if an id attribute is present for points this will be used for interpolation.

Thu. September 9, 2021
19.5.3

Added new option for all snapping modes to control whether we snap to the current geometry, defaulting to on. Cannot be enabled for grid snapping.

Thu. September 9, 2021
19.5.2

Fixed highlighting of points prims in LOPs when selected.

Wed. September 8, 2021
19.5.2

Some UI changes to make Launcher GUI less confusing. Modified Engine Plug-Ins Install Options dialog to better imply that "For Houdini" combo box is for only Maya plug-in installation. Also removed "Packages" tab on Preferences dialog, which isn't needed for now.

Wed. September 8, 2021
19.5.2

In Curve-2.0 SOP, changed the draw modes to make points smooth when initially placed, added the ability to end curves with MMB, and changed the behavior when snapping closed in auto-draw mode to also adjust the first tangent of the curve to create a smoother result.

Wed. September 8, 2021
19.5.1

Fixed MaterialX dielectric_bsdf node under transmission mode ignoring tint and using incorrect IOR on backface hits.

Tue. September 7, 2021
