Paper: Anti-Xray doesn't update as you travel

[lhdev]

What behaviour is expected:

Teleported to a new random location in the world, go into spectator mode with an x-ray resource pack.
All ores are hidden as expected except for those exposed in caves. Travel a couple of chunks away and ores start to become visible. No amount of waiting results in the ores hiding.

If I teleport away and back, when that chunk reloads the ores are hidden. Travel again and the same exposure of ores happens.

Would expect ores to hide as the new chunks are rendered in.

Plugin list:

Grief Prevention
EssentialsX
the list goes on, but none that impact the rendering of ores.

Paper build number:

Paper version git-Paper-253 (MC: 1.13.1) (Implementing API version 1.13.1-R0.1-SNAPSHOT)

Anything else:

    anti-xray:
      enabled: true
      engine-mode: 1
      chunk-edge-mode: 1
      max-chunk-section-index: 2
      update-radius: 2
      hidden-blocks:
      - gold_ore
      - iron_ore
      - coal_ore
      - lapis_ore
      - mossy_cobblestone
      - obsidian
      - chest
      - diamond_ore
      - redstone_ore
      - lit_redstone_ore
      - clay
      - emerald_ore
      - ender_chest
      replacement-blocks:
      - stone
      - planks

Thanks for reporting it. I will take a look at it today. It's probably an easy fix. I might forgot to init DataPaletteBlock with predefined blocks somewhere.

Do you use a custom chunk generator or the default (inbuilt, vanilla) one?

[lhdev]

Thanks, just using the vanilla generator.

[stonar96]

I have now tried to reproduce this in the way you explained it. However I can't reproduce it neither with a 1.13 server (from my original Anti-Xray development branch) nor with the latest 1.13.1 version (from Papers master branch).

My guess is that you either see ores from chunk edges which are possible not obfuscated with chunk-edge-mode: 1 or you see ores above your max-chunk-section-index: 2 setting. Please try again with chunk-edge-mode: 2 or chunk-edge-mode: 3

[lhdev]

If I'm looking around, I can't see any ores. If I travel a few chunks I start to see them in the distance.
As I approach those chunks, the ores are very clearly visible. If I relog or tp away and back, the ores are hidden until I travel again. This is using a simple xray resource pack for 1.13.1 and in spectator mode.

I'm not sure how else to explain this. I tried it with chunk-edge-mode: 2 and max-chunk-section-index: 2 and 3

[stonar96]

This is exactly what I did. I will wait until other people can confirm this bug. Just asked for it in the IRC. Sorry, there is nothing I can do as long as I can't reproduce it.

Edit: Note that you also have to restart your server if you change any settings. Reloading wont work. Can you try it on a test server without any other settings or plugins?

[lhdev]

Totally understand. I'd make a video but that still won't help you. And yeah I can try it on a test server to see.

[egg82]

A video showing the bug in greater detail. At least I THINK this is the same bug. It seems extremely similar. Latest paper compiled/patched with ./paper test and anti-xray values set to the same as first posted.

[egg82]

The important note is that it seems to only affect ores over a certain height. Anything in the deeper levels is still hidden.

[lhdev]

Yeah, that's not quite what I was seeing so I'll see what I can do to better show my experience.

[stonar96]

@aikar The video doesn't show an issue. This still needs testing.

@lhdev If the video shows what you are talking about, then you should set max-chunk-section-index to a higher number. See https://paper.readthedocs.io/en/stable/server/configuration.html for info about the config values. I also recommend useing chunk-edge-mode: 2

@egg82 Thanks for giving it a try.

[lhdev]

@stonar96 it's not the same thing as in that video, I'll figure out how to make one and post it.
I tried chunk-edge-mode: 2 and that didn't help. It's like a render distance thing, as soon as you travel far enough away that you start rendering different chunks, those chunks render with the ores visible. If (using EssentialsX) /spawn and then /back, the ores are gone.

[lhdev]

Ok, the video sucks but it shows what I'm seeing.

You should see that the initial area around me has no ores at the lower Y levels.
As I travel, you can see them in the distance. Once I /back and /back, you see the ores are gone until I travel again.

Current Config after trying different settings:

    anti-xray:
      enabled: true
      engine-mode: 1
      chunk-edge-mode: 1
      max-chunk-section-index: 2
      update-radius: 4

[stonar96]

@lhdev Thanks for the video. This should indeed not happen but I still don't know how I can make it happen. Would be nice if you can also try it on a clean server. If everything works fine, add your plugins and config in stages. This helps me to find out what's actually going on on your server.

Up to now I have tried my best to reproduce the bug, but sadly there is nothing I can do against it until someone explains me exactly under which circumstances (necessary plugins including all necessary config options, server config option, or even gamerules, etc.) this happens. Until then I wont (can't) fix it.

Same or similar issue.

See image for screenshot and config: https://i.imgur.com/EilJDDk.png

Any idea? The client I used was Aristois 1.13.2.
