SKYRIMLE Blackreach Overhaul by Aiyen

[Aiyen]

No I do not think so, the mod currently only affects meshes and object placement. So it will not interfere with that mod.... unless it happen to alter the layout of blackreach radically.

 

Worst case it would be a conflict at the start where you start inside a mesh... but then you should just be able to walk out of it again, or the game will shift you outside of it.
