Does anyone have a basically empty master file... Meaning: no quests, world spaces, minimal items..... simply just enough to create a character and walk around on whatever world space I want to add.

All it takes to create an empty esp is to open the CS and save -> empty file.

If it needs to be an empty esm just use any of the multitudes of programs available for converting esp's to esm's.

If what your wanting was a version of Ob.esm minus all data except something specific, your going to have to copy/paste Ob.esm and convert it to an esp then just open it in the CS and delete everything undesired -> that does ofcourse depend on what that something specific is as for many things it would probably be easier to just use TES4Edit to copy over to a secondary blank.esp some datas.

I tried the delete method and never can get it to convert back to an .esm without major failures. Ill try they TES4edit and see how that goes.
