Flying NPC glitch / ground collision bug. How do I fix it?

[naruto2693]

 

Hello there !

 

There are two primary factors responsible for creating the infamous floating NPCs bug in Skyrim SE. The culprits are mods and graphic settings which increases simultaneous NPC spawns such as the Warzones mod by MyGoodEye, and the uGridstoload= , uExterior Cell Buffer= and fPostLoadUpdateTimeMS= settings in Skyrim.ini.

 

These two factors cause:

- Excessive immediate load on the physics engine.

- Not enough time to load in the core physics components of loaded NPCs before introducing script bloat, thus stalling and improperly loading the physics on specific NPCs.

 

Unfortunately, the solution to this problem cannot be 100% repaired because in some instances you will have an excessive amount of simultaneous spawns crippling the physics engine on NPC load regardless of NPC spawn distances. HOWEVER, there is a solution or a 'fix' which you can use to prevent this from happening in the general open world of Skyrim 99% of the time, by simply increasing the uExterior Cell Buffer= , and fPostLoadUpdateTimeMS range in Skyrim.ini so that it loads up the core NPC physics components into memory at a greater distance before Skyrim Script bloat takes over.

 

1: Contrary to what the S.T.E.P project recommends, use the following formula and apply the result to the uExterior Cell Buffer parameter where x is your uGridstoload value and y =0.3: round( (( uGridstoload=x +1 ) + ( uGridstoload= (x +1) * y ) )^2 )

So if uGridstoload=9 then uExterior Cell Buffer=169. Feel free to vary y between a value of 0.15 and 0.4 depending on the speed of your overall PC.

 

2: Under [Papyrus] increase fPostLoadUpdateTimeMS to fPostLoadUpdateTimeMS=15000.0

 

I run a heavily modded and bloated Skyrim SE and this is the only 'Solution' I have discovered. See if this works for you because it has nearly entirely eradicated this pesky problem form me, just remember to start a new game !

 

Cheers !

 

Ur the best thank you!

 

this doesn't fix it?

GUYS!!!!! I figured it out. At some point you tcl'ed with their prid on. You literally just need to get their prid and then tcl. No ini's required.

Nope. It doesn't work. Nothing happened after selecting flying NPC and typed "TLC". Still flying.

This works for SE not available for LE. I can now run my extra NPC mods in cities with no worries.

Oh my god. This was actually the solution for my case. He wasn't fighting at all and would constantly alternate between flying in the air at clipping through the ground. He's fixed now. Thanks!
