Hi, I am new to the App simulation and magic leap 2, may I have some hints about why the Z value of vergence is opposite between it on Unity panel and it on the App simulation. Any hints are greatly appreciate. ![Capture](https://us1.discourse-cdn.com/flex019/uploads/magicleap1/original/2X/3/399bd9bb0eab577cba13d01266f2c44f61a05579.png) ---

@yanghouze The origin of the Application Simulator is not the same as the origin in Unity. This means that the player rig may have a rotation and transformation that causes the vergence point to have a negative value compared to Unity. ---

Can I change the origin of the Aim simulation to solve this inconsistent, since I don't think doing transform and rotation is a good idea. ---

I'm not sure I understand. Currently, the origin in App simulator cannot be changed. Are you running into any issues reading the Unity values without referring to the values in Apps Sim? ---

No, I can read the value. I am just curious if we can use the data from Aim simulator to double check if my gaze position in unity is correct. ---
