Hi Arnaud, It seems you are building an AR Voyage sample application using “Windows, Mac, Linux” as the platform. We would suggest using iOS as a platform to build this sample application. Steps to follow - Open application in Unity Editor - Goto File-\> Build Settings - Select iOS under the platform and click on switch platform. You should be able to build the application without any issues. Hope this helps. ---

Thanks but I had already switched to the iOS platform when I started working on that project. So the problem wasn’t coming from the platform. I then identified where the problem was coming from the script ‘LightEstimationHelper’ in which the end of the script had the variable ‘normalizedIntensity’ that didn’t seem to receive a value in the last part of the script for some reason. So I simply commented the last four lines of that script and this did the trick. Still something worth looking at for the Niantic team since I imagine that ‘normalizedIntensity’ variable has some purpose. I just couldn’t figure out exactly what it does. ---

Can confirm, I’ve had this same error when importing in Voyage in ARDK for the first time (before being able to choose a build platform), when I switched to iOS, it did remove the error - but I commented out the last 4 lines initially in the file that @Arnaud_Paris mentioned because initially it would open in “Safe Mode” until I resolved that error. I uncommented them out when I switched to iOS build. ---
