I would like an extra flat world with ores without trees or structures.

version 1.12.1

I've done this before, let me get up the custom world JSON for it real quick

Here we go:

{"coordinateScale":1.0,"heightScale":684.412,"lowerLimitScale":1.0,"upperLimitScale":1.0,"depthNoiseScaleX":200.0,"depthNoiseScaleZ":200.0,"depthNoiseScaleExponent":0.5,"mainNoiseScaleX":5000.0,"mainNoiseScaleY":1.0,"mainNoiseScaleZ":5000.0,"baseSize":8.5,"stretchY":12.0,"biomeDepthWeight":1.0,"biomeDepthOffset":0.0,"biomeScaleWeight":1.0,"biomeScaleOffset":0.0,"seaLevel":1,"useCaves":false,"useDungeons":false,"dungeonChance":8,"useStrongholds":false,"useVillages":false,"useMineShafts":false,"useTemples":false,"useMonuments":false,"useRavines":false,"useWaterLakes":false,"waterLakeChance":4,"useLavaLakes":false,"lavaLakeChance":80,"useLavaOceans":false,"fixedBiome":2,"biomeSize":4,"riverSize":1,"dirtSize":33,"dirtCount":10,"dirtMinHeight":0,"dirtMaxHeight":256,"gravelSize":33,"gravelCount":8,"gravelMinHeight":0,"gravelMaxHeight":256,"graniteSize":33,"graniteCount":10,"graniteMinHeight":0,"graniteMaxHeight":80,"dioriteSize":33,"dioriteCount":10,"dioriteMinHeight":0,"dioriteMaxHeight":80,"andesiteSize":33,"andesiteCount":10,"andesiteMinHeight":0,"andesiteMaxHeight":80,"coalSize":17,"coalCount":20,"coalMinHeight":0,"coalMaxHeight":128,"ironSize":9,"ironCount":20,"ironMinHeight":0,"ironMaxHeight":64,"goldSize":9,"goldCount":2,"goldMinHeight":0,"goldMaxHeight":32,"redstoneSize":8,"redstoneCount":8,"redstoneMinHeight":0,"redstoneMaxHeight":16,"diamondSize":8,"diamondCount":1,"diamondMinHeight":0,"diamondMaxHeight":16,"lapisSize":7,"lapisCount":1,"lapisCenterHeight":16,"lapisSpread":16}

If you copy paste that into the custom world preset, you can still edit it from the editing menu. This will make a total flat world, no trees, structures, or grass/flowers. If you mine down, you will find tons of ores. The only thing is, since it is a flat custom world with no trees, the grass is at build height :/ If you want one at a lower Y increase the DepthNoiseScaleY

But, this world will take 5 hours(Not literally) to generate :/
