It doesn’t alter textures that have grass.
No Grassias fixes issues by returning land textures to their vanilla state. Those other mods may not fix grass issues in newer mods, less popular mods, or unreleased mods. If you are using Landscape Fixes For Grass Mods or other fixes, you still need this mod. Landscape Fixes For Grass Mods has a version for Skyrim LE in the Miscellaneous files section of the mod’s Skyrim SE mod page. It can be used alone, but will work best when used in conjunction with other mods such as Landscape Fixes For Grass Mods, Cave Grass Fix, or GroundUp – Anti Grass Clipping. It is a universal fix and will fix issues in both vanilla and modded areas. This mod will fix most of the overgrown grass and grass clipping issues caused by using a grass mod.
