In the German section there is a MOD list inclubs 56 MODs, may be those are the MOD which can surely run in Nehrim.
My Friends have tried to load varieties of MODs in Nehrim, some works well, some would cause crash XD.
I think Nehrim just using some textures from Oblivion foldor. What we need to do just make sure the MOD we want to run in Nehrim no changes any name of those texture files.
If it do need to change the name, may be we can use CS to change the name in Nehrim.esm or Nehrim.esp as well.
