Marty’s mod uses the fake light sources to convert into path traced sources. This is SS level change and not something done in engine. Think of how ENB or Reshade works. This is a plugin for Reahade. Your lighting mods will still work (and will still be recommended)
Community Shaders is also working on doing a complete swap of SSEs lighting system at the engine level that will not suffer from the massive bugs CE has and will be much more performance friendly than ENB Lights.
It’s a very exciting time for Skyrim modding!
My city has both benches and these. I like these because I can lean on them without removing my backpack. I think it really depends on the City whether their hostile or not. I also noticed McDonald’s has them in their order waiting area too.
