I've got into my head an idea of trying to make a total conversion mod for Oblivion. I'm beginning to feel quite comfortable with meshes and .nif files and interior cell work, but I can't for the life of me figure out how to make custom exterior cells.
What I'm trying to do is completely replace Cyrodill as the world my mod will take place in. I know that Nehriman and others have done something similar. Could any of you show me how to create a new worldspace?
Thank you in advance!
