Hi CB,
I haven't had a radio report yet... but I was submerged a lot in yesterdays mission evading DD's
But I just altered a few other sub's parameters in other missions and it works the same, as I said above I needed to zoom in and out a couple of times to enable the camera view.
I'm wondering now to alter those figures some more and see what happens.
Edited to add:
I just found something else out with this, I went to a mission that started in the early morning, still a bit dark. I couldn't get these things to work, but when it changed to daylight I got the ghost icon and the external camera to follow the sub.
So there is more to find out yet.
