Thanks to BlueMind Studio for reminding me of what should have been obvious. When I changed the start level, I got the same results (no mouse rotational control). So, I checked the GameMode (it’s the same for both levels). Then just for giggles, I changed the default Pawn Class. When I did that, the mouse rotation worked perfectly.
So, then I compared my original default pawn class (character) with the one I changed to. The one module that was missing from my original character pawn class. And what I discovered made me feel dumber than a bag of hammers. I somehow had deleted the Mouse Input nodes:
When I added that to my third person character BP, everything worked great. I’m still puzzled why the mouse rotation worked in the original start level BEFORE I had added the Mouse Input logic. But I’m just happy that it now works as it’s supposed to. Thanks again BlueMind Studio.
I don’t know how to Close out this question. If someone can show me, I’ll do it.
Cheers,
