Situation: Iʻm wanting to build on a map while using ConquestReforged and Biomes O Plenty. ConquestReforged now has biome/terrain generation, but I think Iʻve got the right script that disables those. However, Iʻve been trying to replace vanilla biomes with BOP biomes, but nothing I do seems to be working.

Here is the script Iʻm trying to use to replace vanilla biomes with a BOP biome.

all = forAllBiomes()
all.registerGenBiomeRep(biomesoplenty_flower_field)

Here is the script Iʻm using to disable CR biomes.

noBiomes = forBiomes("conquest:conquest_alder_swamp","conquest:conquest_oldgrowth_forest","conquest:conquest_ocean","conquest:conquest_lorein_forest","conquest:conquest_marsh","conquest:conquest_mediterranean","conquest:conquest_mega_boreal_forest","conquest:conquest_mesa_extreme_mod","conquest:conquest_moorland","conquest:conquest_mountains","conquest:conquest_bamboo_forest","conquest:conquest_beach_mod","conquest:conquest_birch_forest","conquest:conquest_bog","conquest:conquest_boreal_forest","conquest:conquest_cold_beach_mod,"conquest:conquest_deciduous_forest","conquest:conquest_desert_mod","conquest:conquest_forest_flower_plain","conquest:conquest_japanese_forest","conquest:conquest_jungle_mod","conquest:conquest_red_desert","conquest:conquest_river","conquest:conquest_tundra","conquest:conquest_tundra_marsh")
noBiomes.removeBOP()

...and here is the crash...

Iʻve never worked with this kind of stuff before, so Iʻm not sure what do to beyond asking for help from people who DO have experience with all this.

You need to place biome resource locations in quotes, which you failed to do in your first script. You also are removing way too many biomes, so a climate type is empty. You need to add biomes to that type so it isn't empty.

Okay, testing all of this now. How do I find out which biomes havenʻt been replaced? Will I have to individually type the vanilla biomes like I had to do with the ConquestReforged and make sure they are paired with their replacement?

Yes, you have to list the vanilla biomes. You can list I'd ranges such as 1-50 if you wish, but resource locations are preferred.

Thanks so much! I did just get it to spawn mystic groves instead of any other vanilla biome, but my friend and I have a "VIP" list of BoP biomes we want to add in. Now that youʻve told me what to do, I can actually sort the BoP biomes over the vanilla ones "evenly" ... WOO! Again, thanks!! Love this mod!
