  • Added a new functionality to find child Customizable Objects from a group node. The Customizable Objects will appear in the "Group Info" section of a GroupNode.


  • Modified morph targets reconstruction data structure which make them easier to serialize and efficiently.
  • Gamepad cylindrical projectors movement improved.
  • Added "IsStreamed" and "TextureLODGroup" columns to the texture analyzer widget.
  • Projector scaling keeps aspect ratio (XYZ) when the white button of the gizmo is pressed.
  • Added option to define a camera rotation pivot point in state metadata.
  • Now warning messages referring to state parameters don't appear when compiling child objects if they are not the owners.
  • Add the option of creating static instance clones to use on construct scripts and other serialized cases
  • Added "Transparency" label to projector occlusion floating parameter.
  • Added new sorting UI method for parameter properties. First, they will be sorted by UI order then by name (if there is no UI order specified).
  • Added a default pin in skeletal mesh node for when no skeletal mesh is selected
  • Added metadata tag that allows sliders to lock into defined positions
  • Remove intrusive checks and change them to warnings.
  • Added UI metadata functionality to cancel the previous hiding of parameter widgets on singular enum options to get fine control on what shows when.

  • Fixed instances not being generated in the blueprint editor nor the level editor.
  • Fixed crash when open CustomizableObjectInstanceEditor and Instance is not compiled.
  • Fixed ClipWithMesNode node crash due to an empty material node.
  • Fixed crash caused by a linked ExtendedMaterial node of a Material node without linked pins.
  • Fixed crashes caused during garbage collection.
  • Fixed packaged game crash due to missing MutableStreamedData files.
  • Fixed MaterialVariation not considering all inputs.
  • Fixed baked skeletal meshes crashing immediately when loaded.
  • Fixed toggle UI widget not displaying theme colors.
