WebAR Image Tracker for Unity

Point a device's camera at a printed image and your Unity content appears on it, anchored and stabilised at real-world scale. Everything runs on a plain https:// page, in the browser, on any device with a camera - iOS, Android, and desktop. No app install, no native AR SDK.

The plugin bridges mind-ar-js (TensorFlow.js + WebGL2) into Unity, so content you author in the editor deploys straight to the web. Typical uses: packaging, print ads, posters, business cards, museum placards, trading cards, and event signage. Share a URL, the user allows the camera, and the experience starts.

🛒 Get it on the Unity Asset Store

Features

• One-click setup. GameObject ▸ WebAR ▸ Controller builds the scene rig; Add Image Tracker adds each target.
• Real-world scale. Content sits under a tracked GameObject at metric scale. A 30 cm model shows up 30 cm on the marker.
• Single-slider tuning. One Tracking Stability dial drives the whole stabilisation pipeline, with an on-device overlay for live tuning.
• Gyro-fused tracking. Rotation runs at display rate on the gyroscope, corrected by the tracker. Brief dropouts carry content on the marker and re-sync without a pop.
• Motion-adaptive, quality-adaptive filtering. Heavy smoothing at rest, responsive in motion, gentle when motion blur starves the tracker.
• Simultaneous multi-target. Several printed images at once, each with its own content.
• In-editor marker compiler. Compiles and quality-checks target images inside Unity.
• URP-first. Built-in and HDRP work via auto-picked Unlit shaders.
• Self-hosted runtime. mind-ar-js and three.js ship in the WebGL template; nothing loads from a CDN.
