Fix missing delete rule icon from light & material linker

• Added support for displacement maps on Houdini materials (Height).
• Added support for material displacement scale (Height scale / effect scale).This will modify the displacement magnitude on the material in Unreal by multiplying its default value of 4 cm.
• Materials parameter attributes (unreal_material_parameter_***) are now also applied to generated Houdini materials.ie, unreal_material_parameter_magnitude can be used to control displacement magnitude
• Added support for AO maps to Houdini Material translation.
• Fixed material not always being properly fetched due to incorrect relative path creation when using node sync.

XPU: improved support for "displayOpacity" and "Af" AOVs

Fixed hotkeys not working in the desktop manager dialog.

Fixed a bug where visible distant or dome light outside atmospherics may have wrong attenuation if camera's far clip distance is too short to fully encompass the atmosphere.

Fixed an issue where certain frame rates were getting incorrectly rounded before being passed to FFmpeg, resulting in videos that played back at an incorrect rate.

Test Geometry: Otto Muscle Transfer recipe now has a new rest_transform stored in the transferred rig. There is also a new option in the joint_position_setup to correct for a character with bent limbs.

Respect the fallback colour for Mtlx Image nodes are referencing UDIM tiles which don't exist.

Fixed a bug in Karma Rendersettings LOP where choosing "UV" or "Texture Coordinates (st)" presets on Extra Render Vars would author invalid data type and cause render to fail with "Unsupported data format" error.

Recipes: Removed node type validation when recipes are installed, as this validation caused Houdini to hang at startup for several minutes when assets were loaded through a network. Before this change, a recipe with missing node type would display an error in the Recipe Manager and the recipe would be set invisible in the tab menu, shelf or in any other menus. If a recipe is placed with missing node types, the Log Viewer still provides a message about the node types that could not be created.

Fixed a crash when drawing the UV island boundaries in the GL viewport

Fixed a bug where the depth-buffer could be re-allocated, even though the size hadn't changed, during transparency passes

Karma Hair and Karma Fur shaders may now be used with Mtlx Mix VOP (Karma CPU only).

Fixed issues with UV expansion in the karma texture baker when using custom AOV names for alpha or when only rendering an alpha AOV.

Fixed a crash in subd and displacement mesh when there are degenerate collapsed edges where both ends share the same vert.

Fixed a potential race-condition that could be encountered during startup that could cause a crash.

Fixed an issue in the animation editor where, when you scaled keys using the "box handle" tool with "normalized values" turned on, the keys got offset vertically when you let go.

Fixed the casing on the time parameter for the lens_parameters VOP.

Fixed a bug in LPE AOVs where excluding a light with certain LPE tag using `^` metacharacter would erroneously exclude lights with empty LPE tag as well.

Backported fix for handling references to husk procedural graphs with environment variables in the path.

Reduced time it takes to resume from checkpoint when deep images are enabled.

Fixed possible crash when resuming render from checkpoint if deep images and husk's snapshot feature are both enabled.

Fixed possible crash when resuming render from checkpoint if deep images and husk's snapshot feature are both enabled.
