[Experimental] - Custom Biomes No Longer Generate

Updated the bug report with new information and updated the reference pack

Custom biome generate, if all player data is cleared, and modified default biomes apply correctly,

" using clear player data button in world settings "

Sadly after save/quit the custom biome's are disabled again, 

 
```
tested versions:
1.16.100.58 Beta
1.16.100.59 Beta
```

Custom biomes still return 'not a valid biome' error in 1.16.100.59

Still affects 1.16.100.60

1.16.100.51 generated biomes, 1.16.100.60 confirmed as not generating custom biomes.

Confirmed still not loading biomes in 1.16.200.51

It no longer crashes, but the custom biomes are still not implemented anywhere.

l still got the "is not a valid biome" message followed by a crash in 1.16.200.51

To be clear, my testing was on Bedrock Edition 1.16.200.51, not Java Edition.

Same crash in 1.16.200.52, even with cave and cliffs turned on.

Still broken in 1.16.200.53 and in 1.16.200.55

Try the format version 1.15.0, it works with beta 1.16.200.55

Using 1.15.0 doesn't change anything, world generation still reverts to vanilla upon reloading

Using 1.15.0 doesn't work for me either. Windows 10 PC.

This still happen even in full release of 1.16.100

Still happens on 1.16.101 come on fix it mojang

Still in 1.16.200

In 1.16.200, you can get around the bug with resetting biomes if you update the behavior package every time before entering the world.

1.16.201 still happens please fix this.

A current workaround is disabling and reapplying the behavior pack before re-entering a world.

Duplicated by MCPE-115844

Overworld biomes have been fixed in 1.16.210.59 however I'm yet to see any custom Nether biomes

Re-did bug report and example pack for the new 1.18 version of the bug

With the newest iteration of this bug, does it work initially but not when you reload the world? Or do custom biomes just not work at all?

Custom biomes do not work at all, I assume because the way vanilla biomes are generated now is not how addon biomes are generated.

I can confirm, that custom biomes no longer generate while the C&C toggle is turned on. I tested it out by making my biome generate everywhere(No C&C). But when I create a new world with C&C toggle turned on, it no longer generates.

This problem affects 1.17.40 as well.

It works on 1.17.40 for me, I downloaded it today so yeah, works pretty good I think

Any update on when a patch will be released?

not yet solved in 1.18.31--- when is this going to be fixed 😞

Has yet to be resolved in 1.19.. Let's not increase the already rising list of bug reports without fixing old bugs.

I can confirm that with the addition of C&C generation, we can no longer redefine vanilla biomes and add custom ones. Custom biomes are still registered by the game, however, components such as "minecraft:overworld_generation_rules", "minecraft:multinoise_generation_rules" and "minecraft:overworld_height" no longer work

I can confirm that this is still an issue in 1.19.2. The custom biomes do not appear, even on mobile.

Affects 1.19.10

Affects 1.19.31

Affects 1.19.40

Affects 1.19.51

I think the only problem with custom biomes is, that they now need a height y and a lot of other stuff, which the broken custom biomes toggle not Supports

Affects 1.19.41

Please fix it Mojang. Everybody is waiting so long for this Feature to come back

It seems that custom biomes are alright on their own, but the "multinoise_generation_rules" component doesn't work as intended on custom biomes.

That's why we're able to use locate biome to search for them or the game crashes if you make an error in the JSON (like have "hills_transformation" in the legacy "overworld_generation_rules" be biome that doesn't exist).

They just aren't able to generate because this specific component is bugged.

Any updates? This feature of addons has been broken for over two years now.

It would be nice to know if it is being worked on.

All creators are eagerly awaiting a fix for this issue. But two years have passed. Please solve this big problem

I can't wait until this bug is fixed. However, it has been abandoned for more than two years. I won't give up until this bug is fixed. please. Mojang. Please fix it soon.

I don't know how this is still not fixed. It breaks a ton of packs a hugely devalues behavior packs a whole.

May I ask what "now technically fall under the caves tag" in the description actually means?

There is a tag 'caves' that overrides regular caves, for some reason, some biomes now fall use this tag.

Thank you for your reply. It's still not very clear to me. Jungle edge (renamed to sparse jungle in Java Edition) and three mesas (mesa, mesa plateau stone, and mesa_bryce, renamed to badlands, wooded badland, and eroded badland in Java Edition) have their own biome files. Why does the description say they're hidden?

To be honest, I haven't done anything with the biome files for quite some (been waiting for custom biomes to be supported again) so they might have fixed it, but there's a certain section specifically for the mesa that doesn't fall under any of the biomes in the biomes folder and can only be overwritten using the caves or overworld tags.

it seems like all of my addons dont wannt work 100%. definitely needs to be fixed soon

custom biomes seemed to be working in 1.20.15 as when i loaded a wild modded structures were spawning just fine, the moment i updated to 1.20.31 however, it ceased. in addition my other mods dont seem to be working properly either as some of the modded items dont seem to exist either.

Still affects 1.20.50.21 preview

Affects 1.20.50.22

I think someone need ti update this issue to 1.20.40

me too.
This bug still aliving.
My addon's biome and features can't spawnable in 1.20.50 ver.
And, why mojang's official guys do not reply this bugs??

I have that same issue I get an error saying get biome registry error in my logs

I did not get the biome registry error message but my biome is not showing up in the world btw I tried biome locate command

Affects 1.21

This issue is about to turn 4 years old and removes one of the most important features of behavior packs. This is getting ridiculous.

This bug report has received no Mojang activity since 2021, is it in the progress of being fixed? Or is Bedrock Edition not intended to support custom biomes. 

(Still affects 1.21.22) 

Can confirm for 1.21.44

The next possible version is Preview 1.21.60.24. Let's hope it's then.

When will this bug be fixed? I've been waiting for almost 5 and a half years.
I have so many ideas for custom biomes that I can't wait to create.
I understand that there is a pretty big problem that it is taking this long, but I would like it fixed as soon as possible.

(Affects 1.21.50)
