SelfieStick

Gallery composition and portable local capture are available as a 0.3.1 candidate. See the capture contract, proof and initial save-isolation incident and the extracted runner instructions. The gallery and Creator/DM now let a user compose one archived-world still, download an exact selfiestick-capture/v1 package, and render its PNG locally from the matching archive. The package verifies the archive and dependencies, uses disposable world/character copies, measures the actual lens/FOV/dimensions and records restoration. The local 0.3.1 proof covers OMEN and AM4; clean-revision release promotion and public downloads follow the fleet plan.

The automated 4K photographic camera engine for Valheim: sub-centimetre pose accuracy, lighting and weather control, and cryptographic proof receipts for world archives.

🎯 The Origin & Why This Mod Exists

Valheim community servers generate massive worlds holding millions of objects across multiple years. Recording and preserving these architectural achievements at photographic fidelity requires positioning cameras with sub-centimetre precision, locking uniform sun angles and weather states, waiting for terrain LOD and physics to settle, and cryptographically proving the exact coordinates of every frame.

SelfieStick (powered by the underlying CameraProof.dll plugin engine) is the automated capture and telemetry tool developed to photograph the Valheim Era Archives.

🌐 Live Public Showcase Gallery

See the live results of this photography engine in action:

• Valheim Era Archive Public Gallery: Thousands of 4K photographs with clickable 3D scene camera links, pitch/yaw telemetry, and exact lens receipts.
• Creator & Builder Stats: Spatial build clustering, contributor kinship, and comprehensive builder directory attribution.

📖 The Photography Essays (Background & Design)

Read the technical and artistic history behind the engine in the 3-part essay series:

1. Part 1: Photographing a world nobody had time to look at — Automating cameras across multi-million-object saves.
2. Part 2: Standing where the builders stood — Reverse-engineering vantage points, player paths, and architectural sightlines.
3. Part 3: The light they built for — Controlling weather, sun azimuth, and lighting sweeps to capture builds as their creators saw them.

⚡ Core Features

1. Unattended Headless Photography

Point the runner at a world save and character. SelfieStick hooks FejdStartup, loads the specified world and character without human intervention, places the camera, waits for world settle, captures the frame, and closes cleanly upon completion.

2. Sub-Centimetre Camera Rig & Optics

Positions the lens at precise spatial coordinates (x, y, z) with explicit yaw (clockwise from +Z), pitch (positive downwards), and field of view. Legacy feet-based rows use their historical 1.7m eye-height offset; gallery composer captures carry an absolute lens and place the game render camera there exactly once. Completely hides the character mesh during exposure (_hidePlayerForScreenshots) so architecture remains unobstructed.

3. Atmosphere, Sun Angle & Flash Sweeps

• Weather Enforcement: Locks environment states (Clear, Misty, Rain, ThunderStorm, etc.) via EnvMan to guarantee identical lighting.
• Sun Angle: Sets exact time-of-day fractions (0.0 to 1.0, e.g. 0.64 for afternoon sun).
• Light & Flash Sweeps: Automatically illuminates surrounding light prefabs within an 80m radius and holds simulated lightning strikes (FlashHoldSeconds = 1.2s) to properly expose subterranean or shadowed builds.

4. Stabilization & Physics Settling Engine

Never shoots prematurely. Before releasing the shutter, SelfieStick holds the camera in place (_holdAt) and waits for terrain chunk generation, vegetation placement, dynamic lighting, and rigidbodies to reach equilibrium.

5. Valheim 1.0 Headless Shields

• Cinematic Bypass: Skips Valheim 1.0's mandatory startup cinematic.
• Cloth Crash Guard: Suppresses MagicaCloth physics evaluation during initial spawn, eliminating the known Linux/Wine/Proton driver crash.
• Character Save Isolation: The exact gallery runner requires unique local character/world copies and checks the client's actual save discovery and Steam character mirrors before and after. Legacy kit/feed workflows have their own lifecycle; use the verified gallery runner for composer downloads. An initial 0.3.0 test saved a capture-only cloud profile after -savedir was ignored; the incident and correction remain documented.

6. Continuous Feed Mode (Hot Loop)

Loading a multi-gigabyte world with 7+ million objects takes several minutes. SelfieStick's Feed Mode (0.2.3+) keeps the world resident in memory and continuously polls a designated feed directory. Dropping new shot plans into the folder executes them immediately without rebooting the game.

7. Cryptographic Proof Receipts

Every frame output is accompanied by an immutable cryptographic receipt in shotplan-receipts.jsonl and receipt.json:

• Client build number (e.g. 25253764).
• SHA-256 hashes of all active plugins and output images.
• Exact lens coordinates, aim point, yaw, pitch, weather environment, and settling clearance.

8. Interactive Console CLI Suite

Full in-game console commands under the camproof_* namespace for live scene composing, teleportation, lighting dumps, and manual captures.
