  New Hierarchy System in Scenery Editor

  Main changes:

  Please check the official documentation about how to use the groups efficiently: Scenery Groups

  Quality of life improvements:
  • Reworked the group object, to make it more flexible and intuitive to use. You can now make recursive groups for any objects, even those outside of airports.
  • Removed the automatic grouping by type for the first level objects ("Scenery", "Airports", "Polygon", etc nodes). You can now make this hierarchy yourself by creating groups and then name, order and organized them as you want.
  • New "Create Legacy Hierarchy" button in the filter menu to recreate the previous grouped by type hierarchy, but using the new group system.
  • You can now open the Rename popup by pressing Enter while an object is selected, and also confirm the renaming by pressing Enter once again. The text is selected by default when opening the popup. This way the workflow is smoother (select and object, press Enter, type the new name, press Enter).
  • Drag and drop for reordering items and change their parent group.
  • Error messages when using the Editor are more explicit and detailed.
  • New widgets at the top of the scenery editor to see which types we are currently filtering by and remove them quickly.
  • Search bars in the Object window are now cleared when you change object type.
  • Removed unused space at the bottom of the Scenery Editor

  • Fixed: Node deletion no longer deletes links outside of the selection
  • Fixed: Cloning an effect no longer replaces non-default material GUIDs in Output block
  • Fixed: The unit drop down menu in the SimVar node now lists all units and their various names
  • Fixed: Visual Effects now work properly after a block has been unlinked, then linked again
  • Fixed: No crash when disconnecting one of several Emitter blocks connected to a VisualEffect block when the effect is spawned
  • Fixed: SimObjects listed in the Spawn tab of the Template Instances/Debugger window now show a name instead of a number
  • Fixed: Visual Effect name no longer displayed large and blurry in the Spawn tab of the Template Instances/Debugger window
  • Fixed: Selection highlight feedback no longer mismatches the node selection after certain manipulations

• Statistics Profiler

  • New column Total Vertex Count which shows the sum of Static vertex count and Skinned vertex count. This total is the one used by the Vertex/MaxVertex Ratio column.
  • Guidelines (Red cell + tooltip) for models with too many vertices switched from the Static vertex count column to the Total vertex count column.
  • New option to hide objects that have no active occurrences in the hiding dropdown menu.

Documentation

• IMPORTANT! With this release the documentation structure and layout has been streamlined and improved, with some pages being moved to different sections, some sections being removed entirely, and the general "look" of things getting an overhaul to make the documentation visually coherent with other Microsoft Flight Simulator sites. This should improve access to the relevant information by providing additional tools that can be used when browsing the different sections and pages, thus making the documentation easier and more intuitive to use. You can find full details of the new functionality and options here: Using This Manual.

  • New! Major change to the Objects window to show 2 columns - one for packages and one for actual objects from selected packages. Navigating this window should now be simpler and more efficient.
  The following fixes to existing features have been performed:
  • Hotfix: :Fixed Projected Meshes not being visible while using the Scenery Editor. Now the LOD 0 is always loaded, so you can see and edit the Projected Mesh properly.
  • Projected Meshes can now be selected by clicking on them directly in the scene, and their rendering has been optimised.
  • Airport groups are now displayed properly in the main Scenery Editor window.
  • The game no long crashes when trying to move an airport group that has components with error/warning.
  • Users will no longer see a "ghost" of the object in the current scene when unchecking "One-click placing" checkbox in the Objects window.
  • A fix has been add to the Airports being rendered rendered pink sometimes due to an invalid material.
  • Sim object bounding boxes have been fixed.
  • Gizmo window can no longer be edited if no item is selected or only locked items are selected.
  • Using "Generate Taxiway Signs" will no longer crash the simulation when the package is not built.
  The following obsolete features have been removed:
  • The "SOLID_DASHED" edge lines option in the Taxiway Path object properties has been removed as it was doing the same thing as "SOLID".
  • All the sub-edition options (add/remove points, subdivide edge, etc) from the Squared Apron right-click menu have been removed since squared aprons cannot be edited in this way.
  • Taxiway Path objects have had various irrelevant material optrions removed, eg: tire mark, end cap, tire gum, etc... Now only "Base Tiled", "Border", and "Center" are available.
  • The obsolete "Scripts" section of the TaxiwayParking properties is no longer visible to the user.

• Statistics Profiler

  • The "LOD Count" column has been removed, and the "LOD" column has been updated to be "LOD / LOD Count - 1", for simplification.
  • 5 new columns have been added that are necessary for the LOD limits profiling. Please see this section of the documentation for more information: IMPORTANT! Coming LOD System Changes (PC and Xbox)

• Visual Effects Editor

  Important! Coordinate systems have been standardized for positions and velocities. They now use the same system, ECEF world or local, depending on a single parameter. This means that:
  • Position and rotation offsets are now always expressed in the space local to the attachment (node or contact point).
  • AttachToEmitterTranslation/Rotation parameters in the Emitter block has been replaced by EmitInLocalSpace.
  The following new features have been added:
  • New! The GetInstanceAttribute node now has an "Age" attribute. This returns the time passed in seconds since the emitter has started emitting.
  • New! Graph Parameters have been introduced. These allow you to specify some RPN code in a model behavior to be executed in a visual effect using the new GraphParameter node.
  • New! Duplication, Deletion, Copy & Paste shortcuts are now available in the node graph editor. Copy and Paste is also supported across documents.
  • New! LocalDirection node to initialize position and velocities relative to your local space for effects that live in world space.
  The following changes and fixes have also been implemented:
  • Clamping of manual inputs in the node graph is now handled properly.
  • Contact point offsets displayed in the Spawner tab are converted from feet to meters to match offset input.
  • "New Document", "Undo" and "Redo" shortcuts now work properly.

• SDK Changes

  • 3DS Max Plugin: Restricted "Pearl" parameters to Standard material type only.
