Glad it got resolved, as I didn't have this issue!

Nevermind its an issue with ShaderSSAO. There's a post on the nexus page on how to deal with it

This is a long shot but after setting this up I have a very subtle (white?) rectangular grid over the display. Not the UI, just the world (viewport?). Not sure how to include a screenshot here. Has anyone else had this happen?

@DART If Living World is loaded after reactive world, they don't. Although I haven't checked properly how it affects ALL overrides, what you get is the reactive world overrides, and some additional living world overrides.

Let me know if you stumble upon incompatibilities. I was thinking in removing living world again since reactive world already covers a lot in the world.

I have been busy on a narcotic (vanilla friendly) expansion as well. Once I finish the mod, I will start testing the modpack again and update it in order that it works optimally! I feel some mods inside the pack function more as cheats instead of adding to the vanilla experience. Sorry in advance for the hiccup, I reccomand now choosing the mods you like from this list and use the load order as guidance. All the best!

Living World and Reactive World together dont cause conflict?
