v1.18.0

Cluster scenarios reach every followed scope, servers report per-connection view hashes, damaged save slots read as missing, and 3D views gain portals, runtime emissive and opacity, frame timing in the overlay and camera/pick on hand-filled scenes. RecursiveAI.OneGame.Physics ships as 1.18.0-preview.1.

Added

• Cluster scenarios can command a followed scope: command: { entity: Arena, name: Hit, scope: 2 } on a client node (and the command_send op's new scope argument) looks the entity up in that scope's replica and forwards the command to its authority, whose trust checks apply as for any player. Unfollowed scopes fail with not_found.
• net_status.followed lists every other scope the client's node is subscribed to, including ones the game subscribed to itself, and each entry carries fullHash and filtered; for a filtered replica hash is the view hash the authority computes for that connection.
• Server hash_at names the connection of each view (clients) and takes an optional client, returning that connection's view hash as view; ServerHost.HashesAt(tick, client) is the API form.
• A 3D view can be shown inside another (portal windows, monitors, mirrors): new Offscreen3D(renderer, w, h, format, sampled: true) renders another Scene3D into a target that Material3D.SetTexture(MaterialSlot3D, texture) binds to any material texture slot, with no model re-upload. ResetTexture restores the file's texture.
• Runtime material changes without reloading a model: Material3D.Emissive, EmissiveStrength and Opacity, and ModelInstance3D.Opacity (plus Label). Translucent surfaces use the existing blended path (far to near, no depth write, no shadow or outline).
• The debug overlay shows per-frame timing: CPU frame, simulation and draw times with a history bar chart, and GPU pass times where the backend has timestamps. The overlay and info operations return the same numbers as timing. GameInstance.Timings, GameInstance.ReadGpuTimings and RenderGraph.ReadPassTimes are the API; timing runs only while the overlay is shown.
• camera, pick and project work for a Render3DStage that has no SceneView3D: Render3DStage.Manual (ManualScene3D, IScene3DProbe) answers over the stage's Scene, and games with their own stage implement IScene3DStage.Manual.

Fixed

• SaveSlots.Exists is false for a slot whose save bytes are damaged (truncated or garbled): it now checks the recorded payload hash, without restoring a world. List leaves such slots out too.
