Loving this mod so far. I'm showcasing it on a couple of different maps on my YT channel. Here's a couple of screenshots from Butschern that I think shows off your hard work :-)
Happy to give something to the community. V1.1 standalone is due to drop soon just seeing if I can sneak in something before I upload it but basically it tweaks the cubemaps to be smoother and adds back moon lighting shadows among other tweaks.
