Hi, I'm learning how to use the HoloToolkit and I'm using the GestureManager to send the OnSelect message at the object pointed by gaze when the user tap. It works with object witch I can attach script where I define the OnSelect function, but I don't understand if this is the right way to do the same if the user tap on the spatial mesh, because I don't know how to refer to it. I don't know how the spatial mesh is added to the scene because it is added by the engine automatically, because I don't know if an Object of some type is created or if the mesh data is saved in some data structure. So, what is the best way to check if the user is tapping Spatial Mesh? I saw that the object collided by the raycast is called like "Surface-\d\d\d\d", where \d is a number. Thank you!
