Hi @rvejendla, try pasting the info into windows notepad first, then copy paste out of that directly into the forum message window. This should remove any formatting or HTML tags that could be causing your issues, thanks.

Hi @rvejendla,

– The TobiiXR_Initializer script attached to the prefab already calls Start() and we recommend only calling this in one place with the correct settings.
This might be the issue as to why you are not getting data from TobiiXR.Advanced.LatestData. I would recommend following our Advanced API getting started (https://vr.tobii.com/sdk/develop/tobii-ocumen/advanced-api/) without making any own changes and see if you have any issues.

– For the issue with the Pico examples not working with a Ocumen license, I would ask to get it working without making any changes or including our SDK within the Pico example scene. This problem likely comes from not enabling “Eye Tracking” in the Pico SDK camera rig, which is necessary and their guides will point to. Our SDK will do automatically if you use the Pico Provider, but not when you add an Ocumen license because then the Pico provider is not used. So it’s probably a issue where you have not enabled and followed their guides to get it working in the first place.

– Importing “Essentials” is an optional step that might pop up when importing the packages through the Unity Package Manager, nothing vital. To import the samples for each package, there is an “Import”-button in the Unity Package Manager you manually have to press after importing the corresponding package.
