How to figure out which AssetBundle is using these font atlases? | Official Unity Discord | Page 1

#

These font atlases by default doesn't being used by any addressables, so I guess these get loaded via an addressable bundle dependency.
The Profiler - Addressable Assets module usually doesn't show anything to me neither in editor nor in builds (very rarely it works, like once in 15 build startings. But last time I checked and it worked was months ago.

#

this is all I can see

#

addressables package is 1.22.3 (now I try to update it)

Loaded since they're referenced by stuff. You can see in the referenced by tab.

no, I can't

#

unfortunately its not that easy

hardy niche Oct 2, 2025, 9:45 AM

#

It is. Assets are loaded if they are referenced in a scene or by something that is loaded. That's basically it. There's no deeper layer to it.

#

@hardy niche this is all I can see

#

Texture2D[] won't tell much even if I open that

#

also Material

#

so I can pursue only the AssetBundle

hardy niche Oct 2, 2025, 9:49 AM

#

short fractal Texture2D[] won't tell much even if I open that

What does it tell? And what does the material tell?

#

And even if you eliminate the asset bundle, it would still be loaded because of the other 2.

short fractal Oct 2, 2025, 9:51 AM

#

hardy niche What does it tell? And what does the material tell?

#

#

continues infinitely

#

#

this is the end of it

#

#

Material is also similar

#

#

and that also ends with assetbundle

Well, you can see that it's referenced by a list of tmp font assets. You can probably find that object and see what it's referenced by.
I bet that it's something deep in the tmp internals, but ultimately, the font is used in the game somewhere.

short fractal Oct 2, 2025, 9:53 AM

#

so I try to figure out which assetbundle could it be, because its not so easy to figure it out

yeah, but where 🙂 because this font atlas is full of chinese characters. And nothing (literally) showing chinese characters in the UI in the screens I made snapshot of

#

the game is set to english localization

Can't you search it by the ID?

short fractal Oct 2, 2025, 9:54 AM

#

hardy niche Can't you search it by the ID?

search it where?

#

its not in Addressables groups

#

in Addressables Groups there are only normal english name group names

hardy niche Oct 2, 2025, 9:55 AM

#

So your game doesn't have a Chinese localization?

short fractal Oct 2, 2025, 9:56 AM

#

hardy niche So your game doesn't have a Chinese localization?

it has, but its not being used anywhere in the game currently (in the moment the snapshot was made)

hardy niche Oct 2, 2025, 9:56 AM

#

Well, then you just need to investigate where it is setup.

short fractal Oct 2, 2025, 9:56 AM

#

that's what I'm trying to do since yesterday

hardy niche Oct 2, 2025, 9:56 AM

#

If you can't follow a lead from one end, you try from the other end.

short fractal Oct 2, 2025, 9:57 AM

#

what would be the other end?

hardy niche Oct 2, 2025, 9:57 AM

#

The localization implementation in your project.

#

hardy niche The localization implementation in your project.

that will be fun

short fractal Oct 2, 2025, 10:10 AM

#

hardy niche The localization implementation in your project.

any better tips? its an 1000 line long class

#

not to mention the components relevant to it

#

I don't know what to look for

hardy niche Oct 2, 2025, 10:11 AM

#

Pff... If it was 30k lines I'd consider suggesting something

#

Figure out how different languages are handled in the project.

#

Are these assets addressable?

#

Assuming that asset bundle is from an addressable, you could search that asset bundle name in the addressable build report:
https://docs.unity3d.com/Packages/com.unity.addressables@2.7/manual/BuildLayoutReport.html

#

hardy niche Are these assets addressable?

no, they are not

hardy niche Oct 2, 2025, 10:19 AM

But I assume they reference the atlas?

none of the groups reference the atlases directly

#

probably indirectly yes

Not in the memory profiler.

#

In the editor

short fractal Oct 2, 2025, 10:23 AM

#

hardy niche Not in the memory profiler.

I meant the Addressables Groups window

#

and in there they are not there

hardy niche Oct 2, 2025, 10:27 AM

#

Well, find what references these assets in the editor.

short fractal Oct 2, 2025, 10:32 AM

#

@hardy niche it seems these fonts are in the Built-in Data (in the Addressables Groups window), and chatgpt says these are loaded during the whole game session.

#

is it true?

hardy niche Oct 2, 2025, 10:43 AM

#

Where do you see that they are in this group?

#

Here's what the docs say, so chat gpt is partially right(they would get loaded if they are in Resources folder):

Built In Data: contains assets in any Project Resource folders and any Scenes included in the Build Settings list. (None of these assets can be Addressable unless removed from Resources or the Scene list.)

https://docs.unity3d.com/Packages/com.unity.addressables@1.20/manual/Groups.html

short fractal Oct 2, 2025, 10:47 AM

#

#

well, these were not included in here before

#

but these were in the Resources folder for months

steady shadow Oct 2, 2025, 10:51 AM

#

Lets remember that Resources stuff cannot be put in addressable groups
If dependencies then they would be duplicated and is a good reason to move all font shit out of resources if you use addressables only.

short fractal Oct 2, 2025, 10:52 AM

#

I just don't understand why its added now and it was not added 1 week ago

#

I made a snapshot on 22th sept

#

and these fonts were not there

#

in memory

steady shadow Oct 2, 2025, 10:52 AM

#

Build addressables in editor to get a build report to see why its there

#

(build report is also needed for the addressables profiler to work)

short fractal Oct 2, 2025, 10:54 AM

#

#

okay, now I can see where are these included

#

okay, now I can see where they are referenced

steady shadow Oct 2, 2025, 10:57 AM

#

good lord thats a big bundle

short fractal Oct 2, 2025, 10:59 AM

#

unfortunately the prefabs themselves are huge as well

#

so it won't be easy to find which gameobject could refer to these

short fractal Oct 2, 2025, 2:29 PM

#

okay, I have zero idea what happened...

#

I identified the common point of these prefabs referring to the localization atlases

#

that was a prefab as well

#

only one gameobject on this common prefab had TextMeshPro on it, so I thought I would remove it.

#

when I removed it, then it solved the issue.(I rebuilt the addressables) I don't remember what happened, when I reverted it.

#

then I tried to identify what parts in the common prefab's code refers to language localizations, and I just commented those out, because it would be weird if these would cause the issue (these codes are used in many other places as well)

#

then I tried to shelved these one by one if I can identify some code change which could trigger this dependency

#

and then I reverted everything related to this

#

I rebuilt the addressables

#

and still the localization fonts are no longer pulled in as dependency...

#

wtf

#

ok, I restarted unity, rebuilt addressables and now they appeared again

steady shadow Oct 2, 2025, 2:53 PM

#

be warned that prefab variants depend on their parent prefab so that can introduce dependencies

short fractal Oct 2, 2025, 2:53 PM

I know

#

its not a prefab variant

#

its just a simple prefab

steady shadow Oct 2, 2025, 2:54 PM

#

gotcha but you think it should not have this dependency on this tmp font?

#

You can use asset database to get dependencies for an asset or use a package that can show them to you in editor
https://docs.unity3d.com/6000.2/Documentation/ScriptReference/AssetDatabase.GetDependencies.html

short fractal Oct 2, 2025, 2:57 PM

#

we already saw the dependencies

#

just the dependencies make no sense

#

all the 18 prefabs referring to the localization font atlases have 1 common part:

steady shadow Oct 2, 2025, 2:57 PM

#

I have seen materials have dependencies to textures it no longer uses, if you use debug inspector mode you can find em

short fractal Oct 2, 2025, 2:57 PM

#

#

this one

#

#

LTSoul-Medium SDF has nothing to do with the other fonts

#

no elements in Fallback list, nothing

steady shadow Oct 2, 2025, 2:58 PM

#

check that font material with debug inspector mode just incase then

short fractal Oct 2, 2025, 2:59 PM

#

steady shadow check that font material with debug inspector mode just incase then

what to check in there?

#

#

ah never mind

steady shadow Oct 2, 2025, 3:00 PM

#

checked saved properties? I dont remember where but I certainly had this issue before

short fractal Oct 2, 2025, 3:00 PM

#

I found it

#

#

@steady shadow

#

but I clear these up in runtime, so no idea still

steady shadow Oct 2, 2025, 3:03 PM

#

at runtime? but does the dep exist at bundle build time?

#

if so then thats the answer. I usually just use the main tmp settings fallback font list

short fractal Oct 2, 2025, 3:04 PM

#

steady shadow at runtime? but does the dep exist at bundle build time?

yeah

#

yeah, I see what is the issue now

#

I just don't understand why it wasn't part of the addressables previously

short fractal Oct 2, 2025, 3:05 PM

#

steady shadow if so then thats the answer. I usually just use the main tmp settings fallback f...

I'm not allowed to clear up that font fallback list in build time though

#

but I understand now

#

there's a prefab, which was recently added

#

which is indeed inside addressable bundles

#

and that contains reference to the font

steady shadow Oct 2, 2025, 3:07 PM

#

someone telling you no sucks but doesnt change the real solution :/

short fractal Oct 2, 2025, 3:07 PM

#

which has indeed has those localization atlases

steady shadow Oct 2, 2025, 3:07 PM

#

having more groups or changing the bundle mode for a group can help there

short fractal Oct 2, 2025, 3:07 PM

#

yeah

#

so I understand why it wasn't an issue before

#

and why it is now

#

@steady shadow @hardy niche thanks a lot for the help. I think I will load the font asset at runtime in this exact prefab, and that will solve the issue.

#

(only for NDA platform)

steady shadow Oct 2, 2025, 3:20 PM

#

cool hope its okay now 👍

short fractal Oct 3, 2025, 9:10 AM

#

it was indeed solved, but these fonts can be loaded by something else as well... not just via from addressables dependencies
