Absolute Nature merged with Anomaly textures, level details and Dead Air .dds terrain masks.
Does not add new plant spots instead only replaces already existing making influence on GPU not as severe as if it were when copying whole levels from Anomaly (tried, discarded due to unjustified heavy fps loss).
Such concoction excludes rather subpar grass, pitch-dark ground and excessive use of overloading trees while keeping just enough resources to mildly upgrade Zone's appearance.
Do not forget to grab Absolute Structures on your way out, you can put it on yourself
