Yeah, i think it was you who mentioned early on that high indirect quality is not needed with the new portals, good tip.
from my understanding, higher Hem samples resolves the image better in relation to indirect lighting quality resolving bad lighting/shadows especially in dark areas… Before people were upping the level of this along with also increasing indirect quality within the editor, from watching let’s make lightmass epic thread. It seems that with portals in 4.11, people simply are keeping the indirect level in the editor at 1 and only increasing hem samples through base.ini
If you can keep it at 8 and get good results then that’s fine, the default is 16.
