Version 4000.0.0

Release Date: 2025-10-20

Starting from this version, EasyAR Sense Unity Plugin will follow the package version control (using Semantic Versioning) required by Unity. Therefore, the version number will be different from that of EasyAR Sense, and the release frequency may also vary. This version of the plugin includes the official version of EasyAR Sense 4.7.0.

EasyAR Sense Unity Plugin 4000.0.0 has undergone significant changes, mainly concentrated in the following aspects:

  1. Changes in Unity and AR Foundation compatibility Starting from this version, EasyAR Sense Unity Plugin will only support Unity 2021.3 and later versions. Support for Unity 6 has also been improved. Meanwhile, AR Foundation support has been integrated into the plugin package. This version will only support AR Foundation 5 and later versions, and its usage has been greatly simplified. If AR Foundation components are added to the scene, the scene configuration and script code can remain unchanged regardless of whether AR Foundation is ultimately used after running.
  2. Up-to-date headset support, with support for multiple OST/VST headsets added After years of polishing with multiple enterprises in the industry, EasyAR's support for headsets has been standardized. Now you can support third-party headset devices through the EasyAR Sense Unity Plugin extension (some data interfaces may need to be provided by the headset manufacturer). This version has built-in support for Apple Vision Pro and XREAL Air2 Ultra. At the same time, it supports Pico 4 Ultra Enterprise and Rokid AR Studio through the EasyAR Sense Unity Plugin extension package. You can also obtain support extension packages for other devices from some of EasyAR's partners (such as Xrany).
  3. Improved Unity component interfaces and significantly optimized the ARSession workflow This is the first version that fully encapsulates EasyAR Sense functions through Unity components. ARSession has been greatly optimized and rewritten. Now you can easily determine the support for devices or functions, start or stop ARSession according to specific situations to switch ARSession or different AR functions at runtime. Meanwhile, you can also use ARSessionFactory to create ARSession and related components at runtime. This version also adds inertial navigation and 3DoF camera functions, which are mainly designed for EasyAR Mega but can also be used independently.
  4. Added multiple development and diagnostic tools This version adds a brand-new EIF recording and playback function. Although EIF recording and playback were also available in previous versions, using EIF has never been so easy. Now you can directly play eif and drive your scene using the diagnostic tool Session Validaion Tool in the Unity editor. Whether it is image tracking, spatial mapping, or EasyAR Mega, the running effects on the device can be restored on the computer. Now you can easily enable the eif recording function in the app using the runtime diagnostic panel EasyAR Diagnostics Panel, or switch the display of key status information of ARSession and its components at any time. Meanwhile, all samples in this version have been rewritten. Running the sample can directly show the ARSession status and the button for recording eif for easy use.
  5. EasyAR Mega tools are fully open This version integrates and releases Mega Studio 2.12. In the future, the plugin will be updated more frequently. The Mega tools on the Unity side will be gradually integrated into the plugin and released together with the regular plugin updates. In addition to the updates in the previous pre-release versions, this version will enable inertial navigation support by default, further greatly expanding the device support of EasyAR Mega. This version also includes support for the latest version of the EasyAR Mega Landmark service. You can apply for using EasyAR Mega through the EasyAR website page. The detailed update content is as follows:
