Native: `removeWorldModel` malfunctioning

[ov-anisa]

Describe the bug

It appears that the removeWorldModel function is not functioning as expected when attempting to remove Level of Detail (LOD) models. However, it works correctly when removing non-LOD models. Further investigation may be necessary to identify the issue with LOD removal.

Steps to reproduce

Execute as below:

1. crun setElementPosition(localPlayer, -59.2240104675293, -1420.678955078125, 29.0296802520752)
2. start map_remover

We have identified an inconsistency with the removeWorldModel function that frequently exhibits unpredictable behavior. Additionally, attempts to resolve the issue by removing the camera/player from the stream and teleporting back have not been effective. Furthermore, invoking engineRestreamWorld(true) does not appear to mitigate the problem either.

In addition, while the native function removeAllGameBuildings performs as expected when it comes to the removal of Level of Details (LODs), it does not meet our requirements, as we need to selectively remove only specific portions of the default map.

Read the "This server script example removes all models, everywhere:" code example.

Edit:
I've checked your code it seems like you want to remove LS and SF. You made two files, each of them has more than 10k lines of code which is absurd. The above for loop runs 20k times for the entire map it deletes all objects with their lod representatives, but in your files there are 10k lines of code which must be heavily duplicated. (even if one model placed multiple times)

If you would like to remove SF and LS from your server you can do it with multiple removeWorldModel with way lower radius in a for loop as seen above.

Also your script takes much time to load and run, not to speak of its size.

[ov-anisa]

for i = 0, 20000 do
removeWorldModel(i, 10000, 0, 0, 0)
end

Not really relevant, not specific to the resource, happens with the below code too:

for i = 550, 19999, 1 do
  removeWorldModel(i, 100000, 0, 0, 0)
end

It is a relevant code example because what you want to do is to delete world objects from the game. As I said, I've checked the resource you given and the whole code relies on the removeWorldModel function which has zero problem, its your skill issue.

I set up a clean local server then ran your resource. It removed SF and LV from the game(some objects 1-2 roads didn't got deleted), but in your files, you have SF and LS filenames.
Here are some pictures:

These parts of the game got deleted after running your map_remover resource.
I suspect that in your local server where you are trying to do things is not as a vanilla as you described.

I suggest you to set up some coordinates from where you use a lower radius to remove parts of the game instead of having these 10k+ lines of files which loads awfully on a client and its too big.
Also if you use 0.25 radius everywhere I'm not sure why do you define it in every line then.

for i = 0, 20000 do
    removeWorldModel(i, 2500, -3211.26685, 485.26520, 24.74507)
end

This code roughly removes SF from the game with parts of Bayside and Mount Chiliad. Of course you can set up lower radius to be more precise.

@derxgbb Its a vanilla server, only got freeroam resource running. If its a skill issue with the resource thingy, then why the below code fails as well?

crun for i = 0, 19999, 1 do  removeWorldModel(i, 100000, 0, 0, 0) end

This is my last comment on this issue.
I couldn't reproduce the bug with a fresh clean install of client & server (Version 22892) on a vanilla local-server environment.

For me the test resource worked well, it removed LV and SF with all HLOD and LLOD. Only some roads near LS stayed.
I couldn't fly through buildings in LS and all the buildings had HLOD models. Unlike on the test videos.

Let's wait others to try reproduce this.

If you need any help, you can ask others in Discord on Scripting help sections.

Certainly, I will await input from others on this matter, as it is clearly unrelated to the script.

Repro:

crun engineSetPoolCapacity("building", 14000)
crun for i = 0, 19999, 1 do  removeWorldModel(i, 100000, 0, 0, 0) end

or

crun removeGameWorld()
crun restoreGameWorld()
crun for i = 0, 19999, 1 do  removeWorldModel(i, 100000, 0, 0, 0) end
