Nova Aetas is set in the world of Calradia, but in a later period. The Old Medieval World is vanishing. A new era is coming and you, the player, will experience this. Nova Aetas is Latin for A New Era. The main targets are realism & extended gameplay.
With an updated version of the improved shaders addon.
Maybe if the enb palette has more grey fading into the white area it should reduce the extreme brightness. Also perhaps the white area needs to not be white but a shade before full white, that might help also.
Don't forget this is the desert. The sun's brightness is very strong for these sandstone walls.
