Seed randomization feature doesnt work

[LilPhyziX]

Expected behavior

I've tested the generate-random-seeds-for-all setting and after several tries, it does not work. i've confirmed by seeing the logs in console saying it generaated 226 random feature seeds, however if you go into chunkbase and put the world seed in there, everything is accurate from ores to structures. You are able to randomize structures by going into spigot.yml and changing feature seeds, however this does not stop ores from being seed cracked and people using ore simulation via the seed.

Observed/Actual behavior

generate-random-seeds-for-all should randomize all seeds including ore seeds.

Steps/models to reproduce

enable generate-random-seeds-for-all

delete world folder

regenerate world

done

Spigot lets you configure one thing, papers config option lets you configure a different thing, the randomisation option only applies to that thing, you need to manualyl scramble the seeds inside of the spigot config if you want that (The two configs are basically completely detatched and spigot uses an entirely different mechanism for populating that stuff, it will never be adjustable from paper.yml, only when we merge the configs can we look at adding such a feature really; as-is, this is more a feature request than a bug report)

so what is paper's seed randomization feature really do then?

[masmc05]

It's for world generation features (as the section name feature-seeds says), more in https://minecraft.wiki/w/Feature
Those are already by default a bit randomised, since different chunk generation order would result in different features being created, so it's harder to notice option's effect

[LilPhyziX]

so how would you randomize ore generation then?

[electronicboy]

Spigot never implemented such a thing in their config, you would need to manually tweak the seeds in their config file

got it. i ask because paper's antixray is very easily bypassable so i use another plugin for raytracing, but seed cracking would bypass that.
