Hi, I would like to use our toolbox with the tobii 4c in unity. I have used the updated core engine and unity SDK, but the"tobii_connect" in Matlab just pop up a cmd window without other result. I wonder it's the engine version problem. But I don't find the Tobii Gaze SDK and the old eyeX engine. If you have the old eyeX engine and corresponding SDK which works fine with the toolbox, could you share it with me? my email is dengdengfan5@gmail.com Thanks
