Fix crash when closing the Scene View pane tab while it is active inside a Python viewport state.

Wed. May 4, 2022

Tue. May 3, 2022

Fixed a bug where an object may be rendered as a different object with the same topology if there are a lot of objects that share the same topology with differing point data.

Tue. May 3, 2022
19.0.608
  • Fix bug that prevents gadget picking to work with nodeless python states.
Mon. May 2, 2022
19.0.608

Fix crash that could occur when python node event callbacks remove themselves upon a node deleted event.

Mon. May 2, 2022
19.0.608

Added a workaround to the Houdini Engine for Unity and Houdini Engine for Unreal plugins for an issue that could cause HAPI to fail when working with Houdini Engine sessions that have a lot of PDG graph contexts.

Mon. May 2, 2022
19.0.608

Fixed a bug with the 'Optitrack (Motive)' device on the Mocap Stream SOP which could cause Houdini on Windows to crash when streaming data from Motive on another device on the same network.

Mon. May 2, 2022
19.0.607

Fixes a bug in an expression in the Follow Path Constraint LOP node. Adds support for multiple point instanced curves as targets.

!unreal 121088.120995

Sun. May 1, 2022
19.0.605
  • Fixed mesh input objects never cleaning up their materials array,slowly bloating up the size of the Houdini Asset Component.This should reduce the memory usage of the plugin when using any HDAthat has input meshes.
  • Fixed crash when outputting a mesh that used the "unreal_uproperty_collisionprofilename" attribute.
Fri. April 29, 2022
19.0.605

Fixed a bug that prevented the HAPI frame from being updated when going back in time in 3ds Max.

Fri. April 29, 2022
19.0.605

Fixed a bug with the ROP Fetch TOP not respecting the frame range settings on the target ROP, when Evaluate Using is set to ROP Node Configuration. The ROP settings will now always be used in that evaluation mode, for example if the ROP Fetch is set to cook a USD Render ROP that's rendering the Stage frame range.

Fri. April 29, 2022
19.0.604

HoudinGL now properly picks up display color for USD Preview shaders.

Thu. April 28, 2022
19.0.603

When importing FBX geometry using the File SOP, a new path option called `convertunits` is available to perform units conversion during the import. For example: `filename.fbx#,convertunits`

Wed. April 27, 2022
19.0.603

Fix bug importing FBX geometry using the File SOP would have geometric transform was applied in the wrong order resulting in incorrect positions.

Wed. April 27, 2022
19.0.603

Fix scene import of FBX files where we were getting unexpected results in the case where the file has FBX nodes whose transform properties had attached FbxCurveNode's without FbxCurve's. The behaviour is now such that the expected results occur as long as animation import is enabled. For the File SOP import of FBX geometry, this can be achieved by using the filename.fbx#,frame=0 path syntax to go into this code path.

Wed. April 27, 2022
19.0.603
  • Fixed manually entered transform still being pushed to Houdini evenwhen "Push Transform to Houdini" is disabled.
Wed. April 27, 2022
19.0.603

Fixed bugs where the Edit and UVEdit states could set pivot parameters while there was a live transform, thereby unintentionally changing it.

Wed. April 27, 2022
19.0.602

In hou.Node.setParmTemplateGroup(), improve the validation for the hou.parmNamingScheme's MinMax, MaxMin, StartEnd, BeginEnd, and XYWH so that valid combinations that were previously disallowed are now accepted.

Tue. April 26, 2022
19.0.602

XPU: Fixed a possible crash when rendering multiple objects referencing the same VDB asset.

Tue. April 26, 2022
19.0.602

Fixed a potential crash in the Blend Shapes SOP when Cache Input Deltas was enabled.

Tue. April 26, 2022
19.0.602

Fixed issue computing shading tangents when there were invalid texture coordinates.

Tue. April 26, 2022
19.0.602

Fixed a crash in the Edit Parm Dialog when deleting a parameter corresponding to a Parm VOP.

Tue. April 26, 2022
