I've been hunting around for tips on this, I even followed the directions for getting MMM to "mostly" work without FOSE.
Trouble is it does not appear to be spawning the hordes of mobs I remember seeing in the game years back. The different creature types appear dispite having noiguanas.esp and such checkmarked and approiate changes to their header's.
Merchants are much tougher than normal so that pluggin works. Monsters and Raiders do show up with different textures and sizes.
I'd like to see the 1 to 3 spawns plug working...
Does anyone know of a way to get that working or another mod, does IWS do the job?
