hi,
i got a problem which i don´t understand after reading the documentation:
- i builded an landscape, which has exactly the recommended size in the documentation
- i builded the landscape
- i run an lighting build : everything is fine
- i sculpt a little bit on the landscape
- i run another lighting build… and receive this warnig:
“ue4 landscape_0 large actor receives a pre-shadow and will cause an extreme performance hit unless bcastdynamicshadow is set to false”
here is my question:
where can i adjust the lighting to get this problem/warning solved
and what are the best lighting setings for my landscape (performance)?
thank you very much for an answer 
greetz
