Game Image for Fallout 3

Very simple mod that enables vertex lighting on all grass records. This can tend to make grass look denser, and adds depth to many scenes. In the vanilla game, grass looks much softer and uses flat lighting. While it's down to preference, the chunkier looking grass can look much better in many circumstances.



Fully compatible with mods that retexture vanilla grass, or replace vanilla grass meshes.

Instructions


Simply drag and drop the contents of the mod into your data folder, and enable with the mod manager of your choice. Alternatively, download using a mod manager such as MO2 or Vortex.


While not required, I would highly recommend adding the following changes to your [Grass] section in your Fallout.ini


iMinGrassSize=40

iMaxGrassTypesPerTexure=6
