I know the faq says that this = missing textures, and to try again, but I have and several textures are purple.
1) Installed Morrowind and Oblivion, clean
2) Ran the Morroblivion installer
3) Dumped all 7 of the resources folders into the Oblivion data folder, followed by the hotfix
4) Dumped the unofficial oblivion patch into the Oblivion data folder
5) Installed OBSE, confirmed to be working
6) Installed the silent voice fix
7) Used NMM to turn on archive invalidation and set my load order to:
Load Order
Oblivion.esmMorrowind_ob.esm
Morrowind_ob - UCWUS.esp
Morrowind_ob.esp
Morrowind_ob - Conversation.esp
Morrowind_ob - Unique Grass
Morrowind_ob - Morroblivion Tree Replacer.esp
Morroblivion_Chargen_And_Transport_Mod_v10.esp
Morrowind_ob - Morroblivion Maps.esp
Unofficial Oblivion Patch.esp
UOPS Additional Changes.esp
Did I miss anything?
