Hello,
i have a normal landscape then i have make a hole down and then i have make a Cave in the Ground under the Landscape. If i start the Game and i go true the hole down to this Cave the Game did Stop. The Game mean that the player is dead. How can i solve it? The goal is, that my player can go true this hole to the underground Cave-System.
Many Thanks in Advance!
Greetings,
Andreas
Unreal has a KillZ-value meaning that players will be killed when travelling beneath a certain Z-value. Go into the world properties and set the KillZ to a lower number.
Thanks very much!!
Hello,
now i have a question about the Exposure:
how can i change the Exposure in the Underground to: Fixed at Log 0
And above the Underground - i mean in the normal World should the Exposure be: Automatic?
Kind regards,
Andreas
Exposure is controlled through post processing. Create two post processing volumes, one for above ground and one for below ground. Position the volumes to match your scene. You will then be able to manipulate the exposure setting independently for above and below the ground. You can read more about the auto exposure/eye adaptation here: Auto Exposure in Unreal Engine | Unreal Engine 5.2 Documentation
As @anonymous_user_964c5f2d said you could just lower the KillZ value so that you wont get killed by it but KillZ is there for a reason: to respawn if you fell out of the world.
To fix it and to re-spawn you could implement the Destroyed event which gets called when the actor is getting destroy (this will execute not only for the KillZ though!). The better way ongoing this is hooking to the FellOutOFWorld function of your actor which is getting killed by the KillZ.
