Houdini Main Changelogs

Houdini 18.5.403 The Instancer LOP now has a parameter to control the type of composition (reference, inherit, or specialize) to use when making a reference under the Prototypes folder to source primitives from the First Input. Fri. November 20, 2020
Houdini 18.5.403 When using the Graft Branches LOP and specifying a primitive which is part of a composition arc (e.g., referenced), a more meaningful message is now emitted. This is also now a non-blocking warning rather than an error. Fri. November 20, 2020
Houdini 18.5.403 The Duplicate LOP no longer produces warnings about a primitive not being transformable when it is duplicating primitives that don't have transforms (such as materials). Fri. November 20, 2020
Houdini 18.5.402 When changing the view while locked to a camera in the LOP viewport, don't manipulate the aperture, focal length, or clipping plane values. These values cannot be meaningfully modified by changing the view. Thu. November 19, 2020
Houdini 18.5.402 Fix crash in FBX Animation/Character Import SOP for FBX files that have non-animated blendshapes. Thu. November 19, 2020
Houdini 18.5.402 Packages - Problem with user array variables.
  • Fix a variable expanding issue with user array variables.
Thu. November 19, 2020
Houdini 18.5.402 Fixed possible crash with multi-frame renders when there's invisible geometry. Thu. November 19, 2020
Houdini 18.5.402 Fix FBX import bug at certain frame rates where the channel evaluation results for joints bound to skin deformers at frame 1 may be wrong. Thu. November 19, 2020
Houdini 18.5.402 Fixed a bug preventing the scale handle from scaling to small values. Thu. November 19, 2020
Houdini 18.5.402 The Agent Clip SOP's clip preview option now allows the clip name to be left unspecified, in which case the Clip Time and Apply Clip Locomotion parameters are applied to the agent's existing current clip. Previously, the clip preview had no effect in this scenario. Thu. November 19, 2020
Houdini 18.5.402 Fix animation export bug in the ROP FBX Character Output SOP when there are only rigid shapes. Wed. November 18, 2020
Houdini 18.5.402 Fix the ROP FBX Character/Animation Output SOPs to output a frame range with a +1 frame shift to take into account that Houdini's frame 1 is actually Maya's frame 0 when given an explicit frame range or outputting only the current frame. Wed. November 18, 2020
Houdini 18.5.401 Nodes other than VOPs are now able to have UT_SourceLocations to highlight their editors. Wed. November 18, 2020
Houdini 18.5.401 Attribute Mirror SOP now will not be confused by matching primitives that have the same bounding box center, as it now uses the barycenter to do primitive matching. Wed. November 18, 2020
Houdini 18.5.401 Fixed a bug in the VellumConstraints SOP when creating Attach constraints in per-point mode that could break any constraints created aftwerwards if they used a restvector attribute (e.g. TetFiber constraints). Wed. November 18, 2020
Houdini 18.5.401 Fixed hrpyc for Python 3 builds. Wed. November 18, 2020
Houdini 18.5.401 The Unpack SOP is now multithreaded when operating on packed primitive types that are non-trivial to unpack, such as Alembic prims. Wed. November 18, 2020
Houdini 18.5.401 Fixed a bug preventing int8 and int16 attribute data from being copied with HAPI_GetAttributeIntData Wed. November 18, 2020
Houdini 18.5.401 Fixed the UV Rotate parameter on the Principled shader so it rotates around W, not V. Wed. November 18, 2020
Houdini 18.5.401 Tag the UV Transform parms to the GL uv transform properties in the Principled Shader so that transforming the UVs in the shader works correctly. Wed. November 18, 2020
Houdini 18.5.401 Fixed bugs where the cell input field was positioned ever so slightly off when the spreadsheet was resized or the user tabbed to the cell. Wed. November 18, 2020
Houdini 18.5.400 Prevent a python exception that could occur in a network editor pane when doing File->New. Tue. November 17, 2020
Houdini 18.5.400 Renamed the PDG job script top.py to topcook.py. This fixes a spurious error message when the top package can be obscured by the job script module. Tue. November 17, 2020
Houdini 18.5.400 Version 2: Failing to acquire a license is now detected by the plugin when instantiating an HDA and will stop the HE session. This prevents further attempts at automatically acquiring a license (which blocks unreal for a few seconds when no license is found). When modifying an existing HDA without a license, this caused unreal to become unresponsive due to an instantiation loop. Tue. November 17, 2020
Houdini 18.5.400 Fixed bug with the new PDG Service panel not saving the services to disk. Tue. November 17, 2020
