Step #70 in the Graphics Overhaul list
It's not necessary activate the
Mournhold Overhaul v2.0 - WG + NPC's.esp file in your load order. Doing so may have an adverse impact on performance in Mournhold, as great as it might look.
If you choose to use Windows Glow (NOT Glow in the Dahrk), replace the
Windows Glow - Tribunal Eng.esp you already have with the one provided by this (or you will have two plugins of the same name in your launcher).
