Made a tool to clean "cache" crash

foxxyfox · December 2016

What is this?
This fixes cache corruption crashes by deleting cache information that your base(s) does NOT occupy.

Why?
I got tired of having to manually clean my cache file so a made a small tool that "cleans" the cache.

What it looks like

Download Here (Subnautica Cache Cleaner v0.11b.rar - 34 KB) ]
Make sure to read the README.txt to see how it works

Heads Up
*This resets nodes so everything that you opened will respawn making the game easier

*It's only needed to clean cache if you are crashing
*After cleaning cache

Go into game and load save
Once your loaded in, Save the game
Go back to the main menu
Now you can play

Source Code
Well hopefully someone finds it useful I had fun making this, last time I programmed was about 10 years ago. I created it in Visual Studio 2015 (Visual Basic)

If you want to see the (horrendous) source code here you go
SubnauticaCacheCleaner Source Files v0.11.rar - 270 KB

Version History
0.10 - Initial
0.11 - Fixed screenshot update when the account has multiple saves

So, for the next version, can you make it clear the entire cache, and then just re-terraform the base, so we can have those batches cleared too? xD ( j/k, although that would be amazing -- but terraforming is on the way out, so hopefully we won't have to do this much longer).

EDIT: x-posted that to Bug Reporting for you here

Worked. winrar backup of savegame folder revealed 2 CRC file errors prior to execution.

PS Marry me

PSS This game rox

Yes, it does the exact same thing, which is why I also linked to this tool in the cache cleaning instructions in case some people would prefer using it.

@foxxyfox Idk why but the app doesnt work for me, i have a win10 64 bits, i need something else ?

@0x6A7232 and Foxy too i tried the batch thing, but it doesnt seem to work, i got 3 crashes after the delete of the batches

What error do you get when you try to launch it? Most likely you need Visual C++ Redistributable for Visual Studio 2015

Excorpion2013 · January 2017

@foxxyfox It doesnt run at all, i open it and then i cant do nothing on it.

donvdp · January 2017

Thank you, ill be sure to give it a quick whip when i get home !

Install the redistributable foxxyfox linked.

Excorpion2013 · January 2017

@foxxyfox and @0x6A7232
It says thta i have another version installed, im a programmer if i change the redistribuitable maybe im going to get some troubles or not ??

0x6A7232 · January 2017

Create a system restore point (might have to enable that on windows 10 first) and see. If so, roll back.

TurielD · January 2017

Hey @foxxyfox , going by the info from this thread this thread the issue is just with the wrecks (they seem to load up and multiply every time you get past) so just deleting the wreck cells should be enough to fix it, rather than deleting all cells save your base.

Could you by any chance make a reverse version of your tool, which only deletes the wreck cells?
According to the wiki, they have particular coordinates, but that's not cells. I'll see if I can find the cell numbers.

@Excorpion2013, Here's a a download link that has an installer and should work for anyone having problems.

I personally don't use this because it installs the program in a weird place, for me it installed it in

C:\Users\Username\AppData\Local\Apps\2.0\BB8HZE4X.5X3\Q70278QH.P5O\subn..tion_8c3c6230bc23abe6_0001.0000_fde2023d8db22575

What I would do is if you are having problems with the first download link is download the installer, install it then uninstall it. This way all the files needed to launch the application are on your system.

@TurielD, Are those the wreck cells? If so I can have a button that just deletes wreck cells. Wait but what if you have a base right next to a wreck?

TurielD · January 2017

no, they're teleportation coordinates, and I think those actually do have negative numbers, so I copied them down wrong. Should be able to teleport to them and mark the cell number.

There's something at 14-18-15, which is very near the spawn zone and likely to be visited (and so progressively worsen) a lot, and deleting just that cell's data solves the problem for most people.

The auto clearing and reterraforming is possible if you learn the insides of the cache files, making the program search each file and looking for modified terrain.

That would explain why i (at some locations) have to Laser Cut through many doors before gaining entrance. I acutally know a location where this is the case. When i get home i will link the camera area.

And why there can be 5 SeaGlide fragments in one container.

TurielD · January 2017

I've stared on the cell list to be cleared:

Safe Shallows 1: 12-18-10
Safe Shallows 2: 15-18-11 (tiny, probably can be ignored)
Kelp 1: 14-18-10 (tiny, probably can be ignored)
Grassy Plains 1: 14-18-15 (this one is *directly* on the way from the spawn area to the Aurora... very likely to cause issues early on)
Grassy Plains 2: 8-18-12
Grassy Plains 3: 10-18-11
Sea Treader: 5-17-8 and 5-18-8

Edit 1:
Blood Kelp: 5-16-10
Grand Reef 1: 11-17-7
Grand Reef 2: 7-16-3

I'd say you're right, based on this thread on SN Steam forums:

No Need To Delete all files in CellsCache and CompiledOctreesCache
I painstakingly went through each files in the CellCache and CompiledOctreesCache by deleting, running the game and restoring the deleted files. Seems there is just one file that's in the center of this lag and crash issue. If you don't want to reset the terrain and resources, just delete this file....

baked-batch-cells-14-18-15.bin In the CellsCache. In the SavedGames directory.

The corresponding file in the CompiledOctreesCache directory doesn't seem to be affecting anything but I deleted that anyway just in case.

Optional delete: compiled-batch-14-18-15.optoctrees

Let me know how it works at your end because it seems to be a good workaround for me here. And again, doing this doesn't reset the terrain or resources.

Also, if it helps any:

Thanks for the tip, we'll investigate. By the way, even though we hardly ever reply, we do read the forums all the time and hints like this one are very helpful to us. Please keep in mind that it might take a very long time to find and fix the underlying issue though.

In the meantime I can provide a little background information about these files.

The CellsCache folder contains data about all the entities (plants, creatures, loot, etc.) in batches the player has seen. If a player never visits batch 14-18-15 then there won't be a file about it in that saved game.

The CompiledOctreesCache contains terrain data only. Terrain data almost never causes issues unless one of the files gets corrupted while writing which may result in missing terrain.

If a saved game runs slow at certain coordinates while a new game runs fine at the same coordinates then there is a fair chance that there is an issue with the CellsCache. The other potential culprits being the batch, global, or scene objects. You don't want to mess with the latter two though, because they contain all your built subs, bases, and items.

By the way the warp command to go to that batch is "batch 14 18 15". Batch numbers are always positive. The dashes are added to the filename for readability only.

So as I said, thanks, we'll add this to our long list of issues to investigate, which you can find on our Trello board. https://trello.com/b/eLEWpq3P/subnautica-playtesting

EDIT again: Asked LumpN what the batch-objects-xx-yy-zz.txt files in the main slot directory did, response:

Well, they contain batch objects. We don't really use them anymore but they are kept for legacy data.

ANGRYABOUTELVES · January 2017

Selecting specific cells to not reset is not necessary anymore as base-building terraforming was removed, but the "Clean Cache" button is greyed out until you select at least one cell to not reset.

0x6A7232 · January 2017

@foxxyfox - ▲ can we get a patch?

SP_Kenny · January 2017

I have SN installed on a different drive then "C"
After running it the first time and having it save the info I expected it to remember where my SN saved games were - it did not
If I wanted to manually edit and save the .ini file what should the syntax be? Currently it is blank

SP_Kenny · January 2017

This is from the program output

16:13:15: Previously saved SubnauticaCacheCleaner.ini loaded
16:13:15: SubnauticaCacheCleaner.ini not found
16:13:15: INI created (C:\Users\******\Downloads\subnautica\Subnautica Cache Cleaner v0.11b\Subnautica Cache Cleaner\SubnauticaCacheCleaner.ini)

For some reason it is creating a new .ini after loading that one that is there and wiping any save data in it

Horman · February 2017

What about my Cyclops and my other ships?

0x6A7232 · February 2017

They won't be touched.

mikeloeven · April 2017

Can you use the full open file dialogue that supports the explorer sidebar that way you can just add the save file to favorites or a library folder and navigate to it in one click. That or just enable the text box so you can paste in a direct link. tree navigation is really outdated and cumbersome especially when you know exactly where the folder is.

0x6A7232 · April 2017

You could try using the batch file I made here. Drop a copy of it into whichever SavedGames\slot00xx folder needs cleaning, double-click when necessary. You could easily make a version that recursively cleared every saved game folder in SavedGames as well, just requires a bit more work.
