Distant terrain turns blue

[Zzyxzz]

Purple textures mean missing or corrupted textures.

 

Blue LOD textures are related with the cell buffer. For example the console command pcb or the ini tweak bPreemptivelyUnloadCells=1

 

You should never f*#@ around with the vanilla settings of the cell buffer, except you increase uGrid.

Psst this glitch appears also on my Radeon RX 580 with 8GB VRam. ENB or not does not matter, MSI Afterburner show a VRam usage up to 5GB, than something cleans the memory usage down to 2GB and than it runs up again.

 

Cell load / texture load at intro start also result to a stutter. Game version and radeon driver are up to date. Would say that textures out if the cell at the horizon are replaced by solid dark blue, looks odd.... :ohmy:

MSI Afterburner has a problem seeing 8GB of V-RAM. They're two stacks of 4GB and when you sometimes see the amount go down to 2GB, it has actually gone up to 6GB because Afterburner disregards the first stack of 4GB.

 

As far as up-to-date drivers go, I've uninstalled AMD's drivers completely and been happily playing without them for just over two months now.

It is a vram issue, but an odd one. Civ5 would do the same thing, but with black instead of blue. Exit, restart would go away for a while, but eventually come back. As if memory was slowly being eaten away.

 

In civ, as you went around the map, you could see it draw in each hex, but some would be black for the terrain. zoom in, wait a bit, and it would draw the tile. Zoom out, and it comes back in other areas. That's a memory issue. Since the blue clears up as you get closer and the game redraws the terrain (zoom in scope doesn't look like it's redrawing, just zooming in on what's already there)

 

Just like the black face bug in SLI. sometimes full black, sometime partial mesh draw.

 

not much you can do about it, update drivers etc. Has to be fixed game side/driver side.

(fixed my sli issues by just getting a newer vid card though) :smile:

 

If you have mods that add meshes/textures, try taking those out and see if that helps, turn down settings, yada yada. standard stuff.

 

If this is happening in pure vanilla, I'd post it to the bethesda forums.

 

 

Edit: My issue persists. The only thing that will fix it will be a new video card, I think. My R7 260X is just too old and weak, now. Next card will be a RX 480 4GB (8GB is too expensive here).

I've tried all the .ini edits, using ENBoost, and nothing works. Googling my issue and it's not a very common one - rainbow textures are far more common but, I don't get those. I'd glady trade for that problem, though :smile:

Â

Edit 2: Meanwhile 3 months later, I have a new monitor and video card (MSI RX 480 8GB) and the problem is still there. It can't be a ram or vram issue (I have 16GB in my system and 8 GB on the card). My card never goes over 60C so it's not overheating and there's ample cooling inside my case.

Been trying to fix this stupid thing myself - blue is a mesh issue, right? You'd think extracting all the meshes (or just landscape) from the ba2 would fix it, maybe even all the landscape materials as well, but no. I'm sure if I extract all ba2's it'll still be there.

It's only this game that I've had this annoyance. Very few people have it (Google "fallout 4 blue terrain" and there's only a couple of results that aren't rainbow textures. Plus there's no fix.

 

Edit 3:

Looks like I might have eradicated it, at last. Had several long gaming sessions where I had to go into interiors and back out (which is when it happened, when the world loaded).

What has so far fixed it for me is Vivid AIO. I'd used parts of it before but now I use everything. Well, except some trees that FO4 Seasons overwrites (so I can have leaves).

So it looks as if Vivid fixed it. Hopefully it stays away for good this time :smile:

 

(Edited without bumping for anyone who comes here from Google like I did).

 

I dont think it has anything to do with vram

I have gtx 1080 and still get that glitch

and I doubt upgrading to 2x gtx 1080 Ti would solve the problem.

 

This game is stupid and if Vault 76 uses the same engine then I will never buy that crap

This post in another thread (about CTD's) made me wonder. I'd been using a mish-mash of landscape texture mods, both 1K and 2K, before my card upgrade, but many were still vanilla textures, and some of those (I've heard) could be as much as 8K, maybe more ? Because I had so many different sized textures in the world, maybe that was what was causing my blue terrain problem. From what I could gather, during my Google searches, apparently my card was out of memory. I used ENBoost at the time (I use an ENB now).

Since upgrading my card, and installing Vivid AIO 2K, which covers *everything* outdoors, it's fine. The only 4K stuff I have is the odd unique clothing/armor mod (Niero's), stuff that usually only my character is wearing. I'd like to use the 4K texture pack but I'm not using an SSD and don't really want to push my luck with reintroducing the blue problem, *if* it comes back.

I KNOW I AM A FEW YEARS LATE, BUTTTT IF YOU HAVE THIS PROBLEM IT MEANS YOU WATCHED A VIDEO LIKE @PHROZAC AND I DID.

 

I forgot the video but basically it required you to add a code in Fallout4.ini (BUT CHECK ALL FILES -Fallout4.ini custom.ini pref.ini and the other pref.ini and default.ini) Check all of these files and do (ctrl+f) and type in âbPreemptivelyUnloadCells=1â and DELETE. This file for some reason broke my f*#@ing game.

 

To ensure you had the same problem as I did, save in a building and load that save. Then, exit the building and enter again, then exit again. If you dont see blue-purplish terrain chances are itâs not the same problem as me. Regardless, I wish all of you best of luck in solving these f*#@ing bugs. Feel free to copy paste this into any youtube video asking people to add âbPreemptivelyUnloadCells=1â.

 

This bug costed me 3 hours of sleep to fix, and I would hate for someone else to endure this. Happy Thanksgiving, and I hope that this will help someone in the future.

star-mystyk,

Â

with Vivid do you experience increased stuttering during cell load?

EDIT: No matter. I'm still getting purple terrain even with Vivid AIO. *sigh*

Quoting myself to say, *groan* I saw the blue terrain again :sad:

Vivid AIO is great, but didn't solve my problem as I thought it did. I'm still keeping it, though.

 

I can't remember why, or what it's called (UserBenchMark?) but, I ran a tool for some reason and it judged my PC and its components. It told me that my GPU (MSI RX480 8GB) was underperforming, due to my CPU being too old or something (i5 4590). So, I think my problem is my CPU being a bottleneck. If I want to upgrade my CPU I'll need a new motherboard, first. An SSD wouldn't hurt, either. One day, when I can afford all that :mellow:

 

Edit: Added possible tool name. It's the last one I downloaded, so I guess that's what it was.
