Change Log - Dungeon Architect for Unreal Engine

• New Unreal Engine 5.4 support
• New Dungeon Canvas - A powerful new dungeon minimap framework, with fog of war, visibility, multiple floor support and much more. Find more info in the release notes.
• New Level streaming code has been upgraded to use UE5's Level Instance feature. This makes the streaming more stable and efficient. This upgrade propagates to Snap Grid Flow and Snap Map dungeon builders
• New Removed Snap Persistent dungeons flag, as they are not needed anymore with the new Level Instance feature. You can now save your snap dungeons that were generated in the editor.
• New Old Dungeon minimaps have been removed and will be superseded by Dungeon Canvas. Dungeon Canvas minimap demos are available for all builders (Dungeon Architect Content > DA_Canvas_Demo)
• New Negation volume works with SGF builder and GridFlow builders. Use this to control the growth of your procedural dungeons. This can be used to blend it with your exist static world geometry
• EXPERIMENTAL: Supply different themed snap modules in the module database. This allows you to create different themed dungeons. These are great for creating simplified low-res 3d minimaps of the dungeon, or you may switch between two timezones, futuristic / medieval dungeon with different art styles
• New New documentation website
• Fix Renamed the C++ structures FCell and FCellDoor to a namespaced prefix like FGridDungeonCell, so they don't collide with other plugins that might use the same name
• Fix SnapFlow and Flow graph assets are exposed to blueprints
• Fix SGF flow graph Create Path node had an incorrect category assigned in the last node in certain cases
• New Grid builder's Clustered Theming setting has it's height variation flag set to false
• New PlaceableMarker's C++ function GetAllowedMarkerNames has been made virtual for extensibility

• Critical Fix Flow Graph samples were crashing the engine due to deployment issues on the previous build (missing Config folder in the plugin directory)
• New Grid Flow Transform logic blueprints have the marker transform as input

• New Snap Connection Selector Blueprints - Apply this blueprint on your snap connection theme graphs. These blueprints give you access to the two room category it connects to and are great for selecting special doors for certain rooms (like boss / treasure rooms)
• New Dungeon Streaming Events - Any actor inside the snap modules can listen to dungeon chunk streaming events (loaded, unloaded, visible and hidden) by implementing the interface DungeonStreamingChunkEventInterface
• New Dungeon Streaming Actor Serialization - Save the state of any actor in a snap chunk while loading / unloading by implementing the interface DungeonStreamingActorSerialization. Check the SaveGame flag on any variable that needs serialization
• New SGF Procedural fill sample. Create only the main rooms (like boss, treasure, shop and spawn) and have the rest of the space in between procedurally generated
• New Run Marker Emitter blueprints either before or after the pattern matcher, thereby controlling access to the marker on the other system. If you want the marker emitter blueprint to have access to the pattern matcher emitted markers, run it after the pattern matcher executes
• New SGF Module Selector blueprints allow you to select or filter out the modules before being placed. E.g. Add (or don't add) the pillar variation of the room depending on whether there's another room on top of it
• New Snap Map builder supports module rotation on individual modules (similar to SGF), instead of having a single global flag to allow / disallow rotation of modules
• New Node Coordinate input has been added to the Flow Graph Module Category selection blueprint. This allows you to decorate your dungeons based on where they are (e.g. a different look on each floor, or a different room type on the edges)
• New Grid Flow Query has a new node to return connected chunk node coords, to allow traversal across the flow graph
• New SGF sample that uses the new module selector to add pillars if there's another module on top of it
• New Blueprint node DARecreateActorInLevel to recreate actors from snap module level to the persistent level. If you have dynamic actors that are part of a snap module (e.g. a weapon that you can pick up or an NPC), it would disappear when the level streams out. Use this node to recreate the actor in the persistent level
• Fix Theme Engine crashed in some instances when nested markers were used on larger theme files
• Fix Landscape Modifier class's properties are exposed to blueprint

• New Unreal Engine 5.3 support
• New SnapMap Custom Module Bounds Shape - Define snap module bounds using custom shapes, allowing for new adnvaced level layouts

• New Flow Graph Branch Selection - Select different paths in your flow exec graph to add randomness to your game
• New New Minimap Framework - The Mini Map framework has ben rewritten. All builders can write to a unified 2D minimap framework. Snap based dungeons support 3D minimaps
• New Snap Connection Entrance and Exit Constraints. Setting a door constraint to Entrance would ensure that we do not exit the room from this door. These are great for puzzle games
• New Pattern Matcher rule graph has a new MarkerListExists node that takes in a list of markers and performs a logical OR on it. This reduces the number of nodes you need to create
• New Procedural Marker Emitters
• New Procedural Transform Rules - These are built-in rules that are used frequently. Apply these to your nodes, without having to create them everytime
• New SGF City Sample - A large drivable city built using the Snap Grid Flow builder
• New Spawn Logic function has access to the dungeon's Random Stream object. Use this for any randomness, so all clients generate the same dungeon everywhere
