Hello Shoib,
Sorry for the confusion, that event has been replaced with ScanProcessed (you can find it in the C# script the the ARScanManager) so instead of _scanManager.OnScanResult += ScanResultHandler, you will want to do _scanManager.ScanProcessed += ScanResultHandler
The arguments are also a little different so in your ScanResultHandler function, the signature should look like private void ScanResultHandler(IScanner.ScanProcessedArgs args) and **args **will contain the TexturedMesh.
If you have any additional questions, please open a separate topic and provide descriptions of your issues so that we can look into them.
