Mixed Reality Utility Kit Overview

• Raycast queries without using the built-in physics engine, including Raycast() and RaycastAll().
• Environment raycasting via RaycastEnvironment() for depth-based queries that do not require Space Setup.
• Find a valid spawn position on the floor, walls, and surfaces.
• Find the best surface position for placing content using GetBestPoseFromRaycast().
• Seat detection via TryGetClosestSeatPose() and SeatAnchors on room actors.
• Key wall detection with GetKeyWall() to find the longest wall with no obstructions behind it.
• Check if a position is inside a room.
• Get the bounding box of a room.
• Get the parent/child relationship between anchors (for example, volumes stacked on top of each other or wall art attached to walls).

• Render the walls such that the textures wrap around smoothly without any seams and scale correctly regardless of wall dimensions. This is crucial for reskinning mixed reality worlds.
• Place virtual objects and furniture to replace their physical counterparts with various options to match orientation, size, and aspect ratio.
• Decorate the scene with procedurally placed content.
• Grid-slice resizing for static meshes, enabling 9-slice style scaling to fit anchors of different sizes.
• Destructible global mesh generation for breaking apart the room mesh into fragments.
• Distance map generation for spatial calculations based on room layout.
• Blob shadow rendering for virtual objects in mixed reality scenes.
• Light dispatcher for passthrough highlight material, sending point light data to enhance lighting realism.
• Room guardian implemented in the application to keep users safe.

• Scene debugger for visually inspecting the anchors to get their location, orientation, labels, and other properties.
• A selection of prefab rooms across multiple categories (bedrooms, living rooms, offices, and more) for testing your application in a variety of environments.
• Scene data provider for loading prefab room data from multiple categories in the editor without a headset.
• Passthrough camera access for retrieving passthrough camera images per eye.
• Object tracking for keyboards and QR codes.
• World locking to adjust VR Pawn position so that anchors stay aligned with the physical world.

• The Mixed Reality Utility Kit Features page describes each MRUK feature in detail.
