I want to create a short, first-person 3D experience that drops players into a realistic crime-scene environment directly in the browser. The core idea is to let users walk through a location, examine evidence, and piece together the sequence of events using authentic forensic science techniques. Smooth performance on modern desktops and laptops is essential, so please think in terms of WebGL builds—Unity WebGL, Three.js, or Babylon.js are all acceptable so long as the end result runs without extra installs. Visual style must feel lifelike: accurate textures, convincing lighting, and believable props that reinforce the investigative mood. Interaction is strictly first-person exploration: no point-and-click cursors, no stylized HUD, just intuitive WASD movement, mouse-look, and contextual prompts when an item is close enough to inspect. A short, self-contained scenario of roughly 5–7 minutes of playtime is ideal. I will provide a written outline of the crime narrative; you will translate it into level layout, evidence placement, simple UI overlays (e.g., fingerprint or DNA pop-up), and a clear “case solved” endpoint. Deliverables • Web-ready build hosted in a test folder that I can drop on any standard server • Full project source with assets, scripts, and clear folder structure • A concise setup/readme covering engine version, build steps, and how to swap in new evidence or text clues Acceptance criteria • Loads in the browser in under 10 seconds on a typical broadband connection • Minimum 60 fps on Chrome and Firefox with standard GPUs (GTX 1060 class) • All evidence items can be inspected from multiple angles and trigger the correct data pop-up • Reaching the end of the exploration displays a summary screen confirming the solved timeline If this matches your skill set and you can deliver a polished, immersive demo swiftly, I’m ready to review your roadmap and timeframe right away.
