Greetings, Recently i started to play Oblivion again so i can mentally prepare for Skyrim. I installed FCOM using the thread here ( http://www.gamesas.com/index.php?/topic/1231051-relz-fcom-convergence-and-ufcom/ ) and Beamer159 FCOM tutorial. Right when i leave the sewers, there are yellow "WTF mesh is missing" sings everywhere and the sky was purple. Any advice on what i can do to fix it?

The game can't find the correct meshes. So, you probably haven't installed them properly. I'm guessing a BSA file or whatever.

If running All Naturel, make sure rhe ESP is active, not just imported. otherwise I think when your close to the Max mod limit...
