I'll take a look at this, but not right away; our feature order is compatible with Vanilla but as the last player to the table, trying to match it to all the other biome mods could be a practically unbounded amount of work.

[dandin87]

All of Fabric 5 dev here. Did some testing. Biome Mods - BYG/BiomeMakeover/graveyard_biomes/promenade/wildbackport/terralith/terrestria/traverse/cinderscapes After disabling Terrestria/Outback all the other biomes seem to work fine. Didn't get to test Oasis as it couldn't find it close enough. But I did locate and teleport to all the other Terrestria biomes. 316 Biomes - https://gist.github.com/dandin87/cc61bf6c6c7c69b32f7702d562fe66fd

[gniftygnome]

I thought we were past the inclusion deadline for AoF. If the implication is you are still looking at our mods for inclusion in 1.19 then I would be willing to bump up the priority on this.

Regarding the difficulty of resolving feature order cycles, I would like to point out it's not as simple as folks seem to think. Any adjustment I make to one biome may impact others and/or create new, different feature order cycles with other mods. Combinations of other mods can have near-cycles which only succeed because no biome uses a particular combination of features. It's therefore possible for a feature order cycle between Terrestria and other mods to be impossible to resolve purely within Terrestria (aside from removing one or more features from the biome). This stuff can take a lot of time to fix (and the quick glance I gave it before my first response indicated it wasn't clear-cut what features were involved, so this one isn't a quick fix at any rate).

[dandin87]

I was just indicating that the Outback biome can be disabled in the config for anyone having the issue. A simple workaround. And letting you know it seemed to work quite nicely with pretty much all biome mods after disabling the Outback. I am pushing for the inclusion of all the Terraformers mods again though, like we had in aof3.

[gniftygnome]

I do expect to work on this before too long ... there's a Vistas issue with Iris next up, and also the question of whether to devote time to backporting Terrestria and Cinderscapes to 1.19(.0) in contention for next in line.

[gniftygnome]

This is Vanilla (from the Savanna biome definition via Yarn for 1.19.2):

        OverworldBiomeCreator.addBasicFeatures(lv);
        if (!windswept) {
            DefaultBiomeFeatures.addSavannaTallGrass(lv);
        }
        DefaultBiomeFeatures.addDefaultOres(lv);
        DefaultBiomeFeatures.addDefaultDisks(lv);
        if (windswept) {
            DefaultBiomeFeatures.addExtraSavannaTrees(lv);
            DefaultBiomeFeatures.addDefaultFlowers(lv);
            DefaultBiomeFeatures.addWindsweptSavannaGrass(lv);
        } else {
            DefaultBiomeFeatures.addSavannaTrees(lv);
            DefaultBiomeFeatures.addExtraDefaultFlowers(lv);
            DefaultBiomeFeatures.addSavannaGrass(lv);
        }
        DefaultBiomeFeatures.addDefaultMushrooms(lv);
        DefaultBiomeFeatures.addDefaultVegetation(lv);

This is BYG (from GitHub):

        byg_invokeGlobalOverworldGeneration(generationSettings);

        BiomeDefaultFeatures.addSavannaGrass(generationSettings);
        BiomeDefaultFeatures.addDefaultOres(generationSettings);
        BiomeDefaultFeatures.addDefaultSoftDisks(generationSettings);
        BiomeDefaultFeatures.addDesertVegetation(generationSettings);
        BiomeDefaultFeatures.addSavannaExtraGrass(generationSettings);

        BiomeDefaultFeatures.addDefaultMushrooms(generationSettings);

        BYGDefaultBiomeFeatures.addSparseOakForestTrees(generationSettings);
        BYGDefaultBiomeFeatures.addShrub(generationSettings);
        BYGDefaultBiomeFeatures.addFirecrackerShrubs(generationSettings);
        BYGDefaultBiomeFeatures.addFirecracker(generationSettings);

And finally, this is Terrestria (from GitHub):

        DefaultBiomeFeatures.addFossils(builder);
        addBasicFeatures(builder);
        DefaultBiomeFeatures.addDefaultOres(builder);
        DefaultBiomeFeatures.addClayOre(builder);
        DefaultBiomeFeatures.addDefaultDisks(builder);
        builder.feature(GenerationStep.Feature.VEGETAL_DECORATION, TerrestriaPlacedFeatures.RARE_YUCCA_PALM_TREES);
        builder.feature(GenerationStep.Feature.VEGETAL_DECORATION, TerrestriaPlacedFeatures.PATCH_DEAD_GRASS);
        builder.feature(GenerationStep.Feature.VEGETAL_DECORATION, TerrestriaPlacedFeatures.ACACIA_DOT_SHRUBS);
        DefaultBiomeFeatures.addSavannaGrass(builder);
        DefaultBiomeFeatures.addDesertDeadBushes(builder);
        DefaultBiomeFeatures.addDefaultMushrooms(builder);
        DefaultBiomeFeatures.addDefaultVegetation(builder);
        DefaultBiomeFeatures.addDesertFeatures(builder);

I cannot find the source code for William Wythers' Overhauled Overworld so I can't comment on what their feature order is. This veers off into the weeds a bit but as a veteran system administrator I would advise against running software with secretive source code (if you must, it should come from a company that could be sued if it is malicious, not from an unidentified individual).

[gniftygnome]

Analysis of this shows addDefaultVegetation and addDesertVegetation both include VegetationPlacedFeatures.PATCH_PUMPKIN and therefore must occur in the same place relative to other feature placements. However, as you can see, while Vanilla and Terrestria place the mushrooms first, BYG places the vegetation first.

This is made even more clear by the Vanilla definition of the Desert biome, which includes the following snippet:

        DefaultBiomeFeatures.addDefaultMushrooms(lv2);
        DefaultBiomeFeatures.addDesertVegetation(lv2);

To put it very bluntly, BYG has got the features in the wrong order and the fact they do not have feature order cycles with Vanilla must be a matter of luck w.r.t. biome placement. I am not very interested in following their lead on this as it seems certain to cause more problems later.

@dandin87 How does one go about disabling it? Never mind, I figured it out myself right after I asked. Also, strange that the order of those two lines would cause issues like this (but then I'm fairly new to Minecraft modding as compared to you guys).

[gniftygnome]

@dandin87 ~How does one go about disabling it?

For anyone else who needs this, find your config directory and edit the terrestria/biome.json file (like .minecraft/config/terrestria/biome.json for some loaders f.e.). Locate "true" next to "outback" and change it to "false".

Also, strange that the order of those two lines would cause issues like this

Yes, it is annoying to say the least. It causes a lot of trouble for modders since Mojang did this. Although I suppose modders could avoid the problem by never reusing any Vanilla features directly.

I've also noticed this issue happens even without William's.

[gniftygnome]

I've also noticed this issue happens even without William's.

Yes, reports indicate either mod is incompatible. A and B both have issues -> either A or B will cause issues. It's tough to condense that into a short blurb for the issue title. I am hoping BYG will fix it on their end. I'm not sure how to even report it for the William Wythers mod.

[Sunconure11]

@corgitaco

Can you look at this?

[gniftygnome]

This is not fixed because that requires action on the part of the other mods' authors, but I think I have found a rearrangement of our features which seems to be compatible with Vanilla as well as BYG and Wythers, so I am calling it resolved on our end. Please report if you can still find any feature order cycles.

[Sunconure11]

I ran into this again.

https://mclo.gs/sezUzTV

[gniftygnome]

I ran into this again.

The logs only mention Terralith. Do you have a particular reason to think it was caused by Terrestria?

[Sunconure11]

I can test. Though I have two other mods that haven't been tested by others against Terrestria; Profundis and Aurora's Decorations.

I've got Galosphere too.

However, I have confirmed they work.

[Sunconure11]

It's Terrestria. Again.

[gniftygnome]

It's Terrestria. Again.

It wasn't Terrestria last time, so I am not certain where the "Again" comes from.

I cannot reproduce the problem using just Terrestria and Terralith. Can you, using a brand new world, and send me the seed?

Also, please add Cyanide to your mods, get it to crash again, and send me the logs.

[Sunconure11]

[Sunconure11]

A minor thing of note is that if I don't turn off Moonlight Lib and mods reliant on it, Cyanide refuses to boot.

https://pastebin.com/FwgJc24C

[Sunconure11]

For the time being, I have Terralith disabled.

[gniftygnome]

https://pastebin.com/EPUGL5pk

Unfortunately, it appears an error in one of the Incenduim JSON files is preventing the game from getting to the error we really want (the feature order cycle one). Generally, Cyanide is supposed to make the game more likely to generate all of the errors before stopping, so I am not certain why that is not happening in this case. I was hoping we could get an error from Cyanide at least indicating what feature is involved in Terralith (it won't tell us anything about the non-datapack mods).

Having looked at the features in Terralith's Haze Mountain biome and compared them to Terrestria's there is no clear problem with the combination of the two mods (which is supported by my inability to reproduce the error with just those mods). Also, I do not see any issue with Terralith's Haze Mountain biome feature order in combination with Vanilla biomes. I am afraid one of the multitude of other mods you have installed is causing the feature order cycle and I can't easily speculate on which mod is actually responsible.
