Fixed an issue where nested empty folders might crash Unreal or Houdini Engine

Fix landscape tile resizing in Generate mode.

Houdini to Unreal StaticMesh translation: fixed an issue where duplicate warnings would be logged in Unreal for meshes with invalid face / vertex data, for each index that is invalid.

Version 2:

• Fix issue where HDA would fail to produce output if HDA is a Sop/Subnetwith display flag set on an output node and Use Output Nodes is enabled.

Version 2:

• Fix unreal_landscape_editlayer_target attribute for Landscape Modify mode.
• Fix landscape input targeting using Input0, Input1, etc.
• Fix Landscape edit layer transforms in Modify mode.

Version 2:

• Added support for the unreal_bake_name attribute that can be used to setthe name of the object(s) generated during baking. The unreal_output_nameattribute takes precedence.
• When baking Houdini Instanced Actor Components the unreal_output_name(or unreal_bake_name) attribute, if set, is now used to determine thebaked instance actor names.
• When baking Houdini Instanced Actor Components the instanced object nameis now used as the default bake name instead of the HDA actor's name(if the unreal_output_name and unreal_bake_name attributes are not set).
• Houdini Instanced Actor Components now support the unreal_bake_actorattribute when baking: the instanced actors are attached tounreal_bake_actor (which is created as an empty actor or re-used from aprevious bake depending on the replacement mode).

Version 2:

• It is now possible to set the default directory used in the browse dialog for File parameters by using the "default_dir" Parameter tag.
• Fixed a crash when trying to assign object path properties via generic attributes with an invalid path.

Version 2:

• Fixed loading of PDG output regression.

Version 2:

• UE5: Fixed an issue where bake to actor would fail and not create anybaked actors / assets

Fixed material update issue for tiled landscapes.

Version 2:

• Fixed an issue where input updates/changes via the public API,especially with curve inputs, would not always take effect.
• Updated the public API documentation to mention that the API returnscopies of the input configuration of an HDA and that to apply changes theSetInputAtIndex() or SetInputParameter() functions must be used.

Version 2:

• Initial support for generation of landscapes with edit layers (usingGenerate output mode).
• Fixed various issues with Modify landscape output mode.
• Add support for edit layer attributes on heightfield primitives.
• Fix issue where temp landscapes were not spawned in the HAC's level.
• Fix issue where HDA would output from hidden or nested subnets.
• Fix handling of output data between Display nodes and Output nodes tomatch Houdini's internal behaviour.

Version 2:

• All UHoudiniPublicAPIInput classes are now API exported in the C++ PublicAPI
• Fixed setting multiparm parameters via the Public API
• AHoudiniAssetActor is now public in C++

Version 2

• Fixed a regression that caused rebuilds to fail with "Fatal error - invalid".

Version 2:

• UE5: Fixed "double cooking" issue when instantiating a new HDA by draggingit on the viewport (UE5 specific).Like in UE4, the HDA is only cooked after being dropped.

• Fixed Wrong tooltip on Landscape Input "Update Landscape Data"

(UE5) Added support for controlling Nanite settings via attributes:

• "unreal_nanite_enabled" (int, 0 or 1 ) can be used to enable Nanite processing when building a StaticMesh.
• "unreal_nanite_position_precision" (int) can be used to set the position precision.Step size is 2^(-Value) cm
• "unreal_nanite_percent_triangles" (float [0 1]) can be used to control the percentage of triangles to keep from LOD0.1.0 = no reduction, 0.0 = no triangles.

• Deprecated the creation of input curves using the curve SOP, in favour of creating input curves using HAPI, using HAPI_CreateInputCurve.

Version 2: added support for Unreal 4.27 on windows.

• Fixed an issue where changing asset input type with a cook error wouldn't allow you to do it - This is an issue for HDAs with minimum inputs.

Version 2:

• Optimized reading of attributes.
• Fixed a bug preventing changing MeshGeneration properties via the details UI.
• The plugin now logs the detailled connection error when failing to create a session.
• Fixed a possible instantiation loop when rebuilding a loaded indie HDA without an indie license.
• Fixed the Houdini Engine status incorrectly reporting a license failure after attempting to use an indie asset with a commercial license.
• The plugin is now using the HAPI GetStringBatch() function when retrieving string arrays from HAPI.This is slightly faster than retrieving each string separately.
• The plugin is now using HAPI's LoadGeoFromFile() function when importing bgeo files instead of manually using a file sop.

• Added support for instancer material instances
• Additionally added support for baking instancers with material instances
• Working for all instancer baking types except foliage due to foliage material being closely tied to the static mesh
• Removed unneccessary parameters from internal functions
• Added an accessor to HoudiniMeshSplitInstancerComponent to be able to get override materials.

• Fixed an issue where material instances were not being generated upon baking with static meshes and landscapes.

Fixed an issue where having a multiparm operator path and then a regular operator path would mess up the input asset order when you add or remove objects.

Fixed an issue where unreal_material_instance was not being applied on landscape outputs.
