I've just checked CNRP Corrol with BC installed - no problems.
Yeah, it's not BC. I think it's Wrye Bash 2.80 not importing stuff like it should.
Questions:
1. CNRP shares some Meshes and Textures with OOO, leading to a small conflict. Any suggestions on which ones to use? Are they the same?
I would imagine they're the same. Since CNRP is an OMOD, I'd just let those ones overwrite OOO's - if you ever deactivate it, the others should return.
2. Anyone been succesful in BSA'ing the Meshes and Textures from the CNRP mods? When I do it, there are always some invisible meshes on certain characters, like the missing torso on the guardsman standing on the left after your enter Bruma Castle.
Can't help you there, sorry. A BSA would be quite helpful, though it'd likely be huge.
