Use the optional mod "less grass for dead edition" to get rid of grasses in the citadel courtyard. in fallout.ini below "[Grass]" use iMinGrassSize=40 (default value is 80)

v1.5 cleans up the bushes and grass in the Citadel courtyard and adds some new trees and plants to this area. It also adds a new tree to the wasteland + some of the textures are updated. Do not clean this mod, it will crash the game!

Outdated, i recommend the other versions! Replaces 2 of the dead trees with slightly larger and more lush trees.

Fixes in 1.0: less "mechanical" looking trees, LOD on TreeDead01 should no longer get stuck

Supposedly better collision for Total Devastation trees. overwrite the old files in meshes/landscape/trees (or whatever the map is). Thanks to zsdf!

These LOD's are for use with the mod Tales of two Wastelands. Dead Version.

This removes grass from some of the grounds that originally doesn't spawn them. The overall look will be a much less grassy wasteland. Probably fits a few areas better while making the overall wasteland more dull. Your choice!
