Have searched for an answer to OOO/MMM/Fransecos compatibility and not found an answer, only many asking the same question. Not very interested in doing FCOM but would like to use these three mods together. Can they be made compatible using Wrye? And if not what will be broken or what kind of weirdness might my game experience if I bash them all anyway?
Try it yourself, perhaps? Blaze (or yeah, bash!) a trail?
Though I'm fairly confident it's been tried before. Many a time.
You could always give Tes4Edit and/or Gecko and/or the CS a go, as well (or instead).
Also... what is it about FCOM that you dislike? And were you aware that it is fairly configurable, in some ways at least?
