kind of interesting honestly…
What will be the benefit of this thing?
And no, I don’t think Unity3D supports this by default.
That is correct, this is not something supported out of the box but I’m sure you could implement support for it via a plugin if necessary (plugins are supported in Pro only and only work on the desktop).
