Originally the work of Revenorror, this is my favorite groundcover mod, combining (I believe) ideas from Rytelier and Remiros.  It looks great and made my Morrowind better, I liked it enough I had to figure out a way to make grass patches to make it play nice with my other favorite mods.  Revenorror has kindly allowed the posting of the mod here after taking it down from their own profile, and the OpenMW patch can be found in the optional files.  

The regional compatibility patches here for Aesthesia Groundcover Reworked are for landscape editing mods that I'd been unable to find elsewhere for West Gash, Ashlands, Ascadian Isles, and Tamriel Rebuilt ver. 22.11.  It should be noted that these patches aimed to eliminate areas of floating grass where landscape levels had been changed, the vanilla behaviour of grass generating in odd places has not been changed, that's just the nature of the generator.  

Patches included for: 
-Beautiful Cities of Morrowind
-Caldera Mine Expanded
-Concept Art Plantations
-Red Mountain Reborn 
-Stonewood Pass Reworked 
-Tamriel Rebuilt 22.11
Individually or in combination. 

The patches for Tamriel Rebuilt 22.11 are added here as regional plugins rather than a single plugin as I kept losing data when attempting to merge them, my apologies.  

The naming convention of the  patch plugins is as follows: 
AC - Azura's Coast
AI - Ascadian Isles
AL - Ashlands
AT - Aanthirin
BC - Bitter Coast
GL - Grazelands
RR - Roth Roryn
VM - Velothi Mountains
WG - West Gash

Select one plugin for each region appropriate to your modlist.  

*AL AesAdGrass BCOM RMR.esp and AL AesAdGrass BCOM RMR SWP.esp should be used with the replacement RedMountainReborn.esp provided by BCOM compatibility patches.  Otherwise Red Mountain Reborn - Aesthesia Groundcover Reworked patches should be used with the original Red Mountain Reborn .esp file.
