20.5.382

Fixed a potential crash in the viewport when displaying an agent shape which contained packed primitives with a boneCapture attribute inside the packed geometry.

Wed. October 9, 2024
20.5.382

Add a name alias for the Attribute Adjust Tags for Attribute Adjust Array. In order to make it for the use case of tagging more discoverable in the tab menu.

Changed the default value of 'create_local_variable' to 'False' in 'hou.Geometry.addAttrib'.

Wed. October 9, 2024
20.5.382

Due to bug fix in shading normals, displaced mesh with deformation motion blur may shade differently.

Wed. October 9, 2024
20.5.382

Fixed a bug where shading normals erroneously used pre-displace normals for motion segments when a mesh has displacement shader and rendered with deformation blur. This bug was introduced in 20.5.305.

21.0.134

Fixed issues in the Configure Joints SOP that produced incorrect results when computing the mass and centers of mass from the collision shape input.

Wed. October 9, 2024
20.5.382

Fixed a "No active drawable selector available" python error in the Curve state when attempting to do a selection through the select icon on the left side of the viewport while in the curve state.

Changed default behavior of the Bright COP to leave the alpha channel untouched.

Wed. October 9, 2024
21.0.134

Changed default behavior of the Bright COP to leave the alpha channel untouched.

Wed. October 9, 2024
21.0.134

Floating windows no longer disappear when Houdini loses focus on macOS. This applies to windows that float on top when the General User Interface -> Keep Floating Windows on Top preference is checked on.

Wed. October 9, 2024
21.0.134

Added a new fbik::GetCenterOfMass callback which computes the center of mass position and total mass of an FBIK skeleton.

Wed. October 9, 2024
21.0.134

Added an option on the Edit Prototypes LOP to not author any composition arc on the selected prim(s). This lets you use this node to create a class prim structure at the destination of an existing inherit arc.

Wed. October 9, 2024
21.0.134

The Edit Properties LOP and nodes built on that base that are affecting a USD relationship can now append, prepend, or remove prims from the existing list of targets.

Wed. October 9, 2024
20.5.381

XPU: Fixed a bug in expanding a custom MaterialX node

Wed. October 9, 2024
21.0.133

Improved the transfer speed of data to Houdini from Unreal for large sparse data sets.

Wed. October 9, 2024
21.0.133

The Lattice SOP allowed for 0.01 units of wiggle room for the source geometry's points to sit outside of the rest lattice and still be deformed. The 0.01 units of wiggle room was in "parameteric space" and has been replaced with a real world unit which is configurable by the new "falloff" parameter. The new parameter defaults to 0.01.

Tue. October 8, 2024
21.0.133

Adds geo::Lattice::2.0 which includes support for Nurbs lattices and a falloff port allow a little wiggle room when a point sits just beyond the extent of the rest lattice (probably by means of a small deformation or numerical imprecision).

Tue. October 8, 2024
21.0.133

Adds the new "Nurbs" interpolation type and a falloff parameter to the Lattice SOP.

Tue. October 8, 2024
21.0.133

Added 'A' (albedo) event type in light path expression so that it's possible to write out albedo AOV based on specific path or BSDF component.

Tue. October 8, 2024
21.0.133

Fixed potential crash creating new viewer panes via hotkey.
