Image Gen is not applying new biomes and Crashes when adding new structures[BUG]

[WannaGrenade]

This is a continued thread from my earlier "suggested" post, just to give you a full list more accurately stated. I have found multiple bugs.

---

ISSUE 1: Added "DATAPACK" for new biomes causing Image gen to not generate by image

I downloaded terralith for more biomes, wondering if the fabric mod could support it. I installed terralith.zip in the world/datapack folder.

I should note these do not MODIFY vanilla biomes but introduces NEW biomes by using 1.16 introduced biome jsons.

I then made a 'biomeImage.png' map ONLY for vanilla biomes, desert, snow_tundra, and ice caps excluding any terralith biomes and installed it in imgen/image.

I used this config:
{ "configVersion": "1.3.3", "biomesImageName": "biomeImage.png", "biomesImageScale": 8.0, "repeatBiomeImage": false, "repeatMirrorBiomeImage": false, "defaultBiome": "minecraft:ocean", "continuousGen": true, "largeBiomes": false, "customBiomes": [ { "biomeID": "modid:biomeid", "RGB": "0x000000" }, { "biomeID": "modid:biomeid", "RGB": "0xFFFFFF" } ], "customHeightMap": false, "heightMapName": "HeightMap.png", "heightMapScale": 1.0, "repeatHeightMapImage": false, "repeatMirrorHeightMapImage": false, "seaLevel": 63, "placeVanillaStructures": true, "customStructures": false, "customStructuresImage": "structureMap.png", "repeatStructureImage": false, "repeatMirrorStructureImage": false, "useBlackList": false, "blackListApplication": 2, "structureBlacklist": [ "modid:structureid", "modid:structureid" ], "customStructuresRGB": [ { "structureID": "modid:structureid", "RGB": "0x123456" }, { "structureID": "modid:structureid", "RGB": "0x024680" } ], "lakeFormationPercentChance": 0.5, "segmentImageWidth": 512, "segmentImageHeight": 512, "imageCacheSize": 4 }

I encountered issues. I was able to narrow it down to this.

When my datapack is not installed and region files are regenerated the world appears like the map. no datapack loaded

When my datapack is installed I do not get imgen generation. datapack loaded

ISSUE 2: Added "FABRIC MODS" for new biomes causing image gen to not generate by image.

Wanted to give some more info. It might be more than the just datapacks.

https://imgur.com/a/AxhTyIq

I decided to try using the terralith fabric mod version instead of the datapack and similarly as before, once generating new chunks, world generations returns soley to normal/terralith generation and does not follow the image.

This is my map image: https://imgur.com/lAK8GH4

I conducted this with another mod called "sensible biomes" that added new biomes and the result was the same.

---

ISSUE 3: Added "FABRIC MODS" for new structures / modify structures cause server crash

This crash can be avoided if in the config "placeVanillaStructures": is set to false, but it means no structures spawn. I have not investigated if the structure map will get around this.

This was tested with the fabric mods:
- betterdungeons@1.17-1.0.1
- bettermineshafts@1.17-1.0.1
- betterstrongholds@1.17-1.1.1
along with the required APIs
- YungsApi-1.17-Fabric-16
- cloth-config-5.0.38-fabric

This Issue generates a crash report:

I have decided to upload my server settings so you can playtest.
setup

[28Pollux28]

ok thx for your feedback. I'll look into it, but can't give you an ETA

[WannaGrenade]

ok thx for your feedback. I'll look into it, but can't give you an ETA

No worries. I have many other things to investigate until I would like to get my server running, and in this case, a map generated. Take your time!

Also setup is uploaded

[WannaGrenade]

I did further testing for Issue 3.

EDIT: It appears I can get some custom structures from datapacks working in the previous 1.17 build 1.3.2 but not structures from mods. Rather any structure from mods are being forced into vanilla types. In this uploaded case its forcing new stornghold structures into swamp huts

set up for 1.3.2

If I enable these settings when I have mods enabled for new biomes/structures along with a structures map for the RGB value, I can generate vanilla structures.
"placeVanillaStructures": true, "customStructures": true,

With these settings if I attempt to enable a custom structure with the following RGB code 0x3b7eb7, (I tested the current RGB value for a custom structure with a control of the vanilla pillager outpost which would spawn if the server launched properly) there is a crash upon start up.

Should I enable the same custom structure in the config with the following RGB code 0x123457, There is no crash but the structure does not spawn.

Should I enable not a modded structure but a structure provided by a datapack, in this case more_structures:pillager_outpost_badlands from wythers datapack, the server will launch. But when I join and enter the chunk where it would be loaded I receive an error in the console and I am booted from the game. No crash report is generated.

The console reads

Hi ! Sorry it took so long, But I think I've found the issue that lies behind your first issue. Some datapacks use custom generation (teralith in particular) and therefore override the chunk generator used. The way Minecraft is handling it is to give priority to Datapacks over everything else, including mods.
While I'm working on a solution, a possible fix could be to delete in the datapack in data/minecraft/dimension the overworld.json file. I've not tested it so back up the file before you do so.

Hi Pollux, Sorry for the late response this semester has been rough and my pet project was put to the side. I did in fact try this and it did not help. Have you made any progress?

[28Pollux28]

The semester has been rough for me too and I don't have much time to code these days. Tbh I worked on it in September but I don't recall what I achieved to do back then. I don't know if I'll be able to solve this
