Hey Sheson, I think I found another possible bug for PBR lods. Everything for the most part seems to be working properly but I've found that when using Tomato's Whiterun PBR and generating lods, it seems like SMIM textures take priority.
Only when I change the file pathing to overwrite SMIM with textures located in the PBR folder it seems to work,

For example, copying the texture folder located inside the PBR folder and pasting it outside of it to match vanilla or smim structure.

When I do this the lods match and everything works fine like in this photo.

Everything else, like trees and mountains seem to work fine. This is the only issue I've come across recently.
Here is the log (I think this is the correct log to post, if not let me know)
