Houdini Main Changelogs

19.0.901

Rewrote the Pressure constraint in the Vellum Solver to make it deterministic on GPUs at high constraint counts, as well as to avoid hanging that was occurring with the latest Ada architecture GPUs from NVIDIA (e.g. 4090).

Tue. February 21, 2023
19.0.896

(UE5) Fixed regression that caused Foliage Types to be instantiated as meshes if the "unreal_foliage" attribute wasn't set.

Thu. February 16, 2023
19.0.895

(UE5) Fixed incorrect instances transforms when using Foliage. (either by instancing FoliageTypes or by using the unreal_foliage attribute).

Wed. February 15, 2023
19.0.895

The Add Variant LOP will no longer create invalid USD internal references when creating a variant in which some prims in the variant directly reference other prims within the variant.

Wed. February 15, 2023
19.0.895

Added a new export option to inputs "Export Material Parameters" When disabled, the plugin will not be sending each material parameters in the input object's materials as attributes. This can be very useful at reducing cook times when sending big mesh, with materials that has a lot of exposed parameters.

Wed. February 15, 2023
19.0.894

Added DCM Z-Bias parameter on Render Product to merge samples that are similar in depth in deep image output.

Tue. February 14, 2023
19.0.893
  • Fixed an issue when baking Static Mesh (created from packed "one instance instancers").It caused the first mesh to be baked multiple times, and the others to be ignored.
  • Fixed potential crash when loading a new map.
  • Fixed potential ensure failure / crash with the PDG Asset Link when baking to Actors.
  • merged PR#221 from @yuhe00:Fix compilation error when building for Android platform with clang 14.0.
  • merged PR#230 from @fullike:Fix baking fails if OutputComponents has no elements.
Mon. February 13, 2023
19.0.893

Fixed a bug in the Light tool that could result in the view direction being unexpectedly reset.

Mon. February 13, 2023
19.0.893
  • (UE5) Fixed regression that prevented ProxyComponents from being properly cleared.
  • Fixed regression that caused an infinite cook loop when using spline in world inputs.
Mon. February 13, 2023
19.0.889

Fixed double transform issue when import input as ref. is selected

Thu. February 9, 2023
19.0.888

TOP Networks have a new "Save Scene File if Required" toggle, which can be disabled in order to turn off automatic saving of the scene before cooking the graph.

Wed. February 8, 2023
19.0.885

Fixed a problem where foliage types were not baked correctly.

Mon. February 6, 2023
19.0.883
  • Added support for all types of image packing (RGB, BGR, RGBA, ABGR etc..)This fixes a crash when trying to create an texture that wasn't packed as RGBA.
  • Fixed a regression that caused the plugin to not automatically refine meshes whensaving the level on World Partition World.
  • Fixed a regression that broke the "Proxy refinement by timer" option.
Fri. February 3, 2023
19.0.882

Work around a bug with JIT code generation in VEX which triggered a bug in on Skylake architecture processors

Thu. February 2, 2023
19.0.882

When saving geometry files to disk, provide direct disk access for files where an FS helper implements getPathOnDisk for the file path. This allows some file formats (like .vdb) to provide a richer feature set for files in this situation.

Thu. February 2, 2023
19.0.880

Fixed issue when creating .rat files where where aggressive compression could sometimes cause issues and create corrupt files. This was most noticeable in deep images (mantra).

Tue. January 31, 2023
19.0.880

Fixed the scene graph tree filtering so that setting the filter to "light" will implicitly match against "*light*".

Tue. January 31, 2023
19.0.874

Update hkey and sesictrl to provide the website with extra information when generating entitlments so that the website can correctly decide which format to generate the licenses in.

Wed. January 25, 2023
19.0.873

Fixed an issue that prevented DataTable with only one row to be sent to Houdini.

Tue. January 24, 2023
19.0.867

Data Table Input: enum values are now sent as strings, not ints.

Wed. January 18, 2023
19.0.866

Fixed world inputs ignoring changes in scale value on Spline Components.

Tue. January 17, 2023
19.0.860

Make some loputils related to parsing instance strings more robust in the case where the instancer is a custom prim type (not a point instancer).

Wed. January 11, 2023
19.0.858

Fixed issue with modifier HDAs sometimes leaving behind dead vertices when operating on editable poly meshes.

Mon. January 9, 2023
19.0.858

Fixed a bug in the RBD Packed Object DOP where the initial packed transform was incorrect if both the `pscale` and `scale` attributes were present.

Mon. January 9, 2023
19.0.858
  • Fixed an issue with UV maps being incorrectly imported from Houdini whenthe UV channels are sparse.
  • Fixed an issue with the plugin only welding UVs in the first UV channel.Now, UVs will be correctly welded in all available UV channels.
