Other interior modifications and improvements

feature

Supports Old Generation, Next Generation and Anniversary Editions

Generate offset data to significantly improve the runtime performance of loading units

Fully multi-threaded, greatly improving generation speed (gosh, don’t forget to add threads)

Contains custom loading menu for showing build progress (shout in ActionScript3)

Cache output, making continuous loading almost instantaneous

Allow non-main plugins to actually load offset data

~~Mining Bitcoin in the background~~

What to expect

Less lag when traveling across the world

Dump more data in your data directory

What not to expect

Bethesda don't keep updating games that are 10+ years old

JuiceHead didn't tell me the size of the new update

Weapon or armor mod did not make it into this month's module

Comprehensive and consistent animation revamp of FO4 weapons

It’s actually a very good gooning mod in Fallout 4 (for immersion, of course)

Reduce AI rough mods (thankfully this mod was excluded)

Beeper and I finished that [REDACTED] mod (cut like the file)

~~Community Shaders for FO4~~ (This actually happened)

New Vegas is being remade/remade (it might actually happen)

Technical discussion

Exterior cells are not initialized at startup, like most other game objects,

instead they are loaded at runtime, when the player is near them.

To quickly find said cells, the engine, every since (presumably) Oblivion,

uses something called cell offset data.

It tells the game where cells are located inside each individual plugin.

If not present, the engine has to effectively search through your entire loadorder for a given cell,

which can be really performance intensive, especially if you have many mods that add/edit cells.

The problem is that they have to be generated using the Creation Kit's version control system,

which no soul on earth uses.

The tool xEdit even completely strips cell offset data from plugins on save.

And even if you do all the effort to create them,

the engine won't load them for non-master plugins.

This mod solves all of that by generating missing cell offset data at startup for all loaded plugins,

while also allowing non-master plugins to actually have them loaded by the engine.

FAQ

Q: What is the difference between this module and Faster Cell Lookup?

A: My mod has been developed and sitting on the system for a few months, so it's a pity that a similar mod was released a few days ago. The main difference is probably that my mod is completely handmade, doesn't rely on any AI or large language models, and also includes a custom loading menu.

Notes to mod developers

You can include pre-generated unit offset files with your module,

This way users don't need to generate these files themselves.
