Yes, that is correct.
There is likely to be letters involved, an example entry could be
Section:205
Row:G
Seat: 12
There will not be individual actors per seat, because our scenes are entire sports stadiums that can have 10s of thousands of seats. As such, an entire section of seats will be collapsed into a single static mesh. Seat coordinates will be stored in a separate file and we hope to be able to reference that file when naming the seats by the means I’ve described.
So basically I’m trying to just proof-of-concept this idea one baby step at a time. I have a separate thread running regarding the communication between Unreal and referencing that external coordinate data. In this thread I’m trying to flesh out Text Input ability.
