Requirement: Export the camera position and rotation Angle in 3ds Max into the game

3ds Max uses the right-handed coordinate system with the Z-axis up, while the game uses the left-handed coordinate system with the Y-axis up. Change the position, exchange Y and Z, but what about the rotation Angle?

It's really unrealistic to close a Unity question with math answers. OP just needs the obvious and simple Unity solution here. – Fattie Apr 09 '21 at 11:02
Looks like [this answer](https://stackoverflow.com/a/41910491/1092820) on one of the linked dupes might work. – Ruzihm Apr 09 '21 at 19:07
