📋 About This Mod
FROST Cell Fixes (FCF), and Interior Cell Fixes and Exterior Cell Fixes before, was born out of discontent with the then available fixes for the broken previs and precombines (previsibines henceforth), resulting from FROST's overhaul. Jacq Frost used the "antiquated" roombounds for interiors that was partial (and poorly) implemented in Fallout 4, and was bloated with a bunch of other changes I did not care for. FROST Unofficial Boston FPS Fix did a better job for the exteriors, but in the process reverted many of FROST's changes by reintroducing vanilla previsibines. So I took it up me to redo all previsibines for all cells and world spaces, relevant to the FROST universum.
But there it didn't end. By starting to fix long overdue bugs, like the impassable stone arc and invisible manhole, it became a much bigger bug fixing project, including also vanilla bugs not (yet) covered by UFO4P.
What this mod does:
-
[]Rebuild previsibines for all cells and world spaces, resulting in a performance boost (moar FPS, yes)
[
]Removal of all left over signs and graffiti related to the vanilla factions and locations[]Plugging countless previs holes
[]Some LOD fixes
[]Retexture of BoS and Gunners barricades
[]A multitude of seams, misaligned objects, clipping, z-fighting, etc
[]water audio bugs
[]Cleaned up Faneuil Hall exteriors
[]Modified Covenant entrance and fixed miscolored landscape
[]Small world additions
[]And more...
But not all of this is my own doing, but a collaboration of efforts by various people. Since v2. 0 of ICF, every new release was built on the foundation of BenRierimanu's Previs Repair Pack (PRP). For a great deal of vanilla fixes, kudos should go to BenRierimanu and his contributors.
Just like PRP, these mods are also integrated in FCF:
-
[]Boston Airport Windows Transparency Fix

[]Far Harbor - Cliffs Edge Hotel Wall Rest Ring Lower Fixed

[]Settlement Dead Zone Fixes (Max compatibility version)
[]Diamond City Billboards
