Something happened recently which has drastically reduced the render distance for trees - happens on ALL maps/saves.
I've gone through Compatibility Report, updated all mods, etc - zero conflicts/issues. I'm fairly certain that a setting got changed somehow (as it only started happening last night) but I can't seem to find where to increase the render distance.
(I know I'm going to feel stupid when it turns out to be something simple but, for the life of me, I can't seem to find it.)
