This add-on changes the generation of Minecraft overworld's surface to a flat one, exactly like superflat worlds, however with this add-on enabled, all caves, trees, grass and other natural generation will be generated with some exceptions.
Similar biomes will have their unique flat layers, desert - sand and sandstone, plains - grass and dirt, oceans - water and gravel and more.

Note!
Following features won't generate in the new flat terrain:

• Villages (Villagers and Golems will generate.)
• Pillager Outposts (Pillagers will generate.)
• Mansions (Evokers and Vindicators will generate.)
• Temples (Desert Temple treasure will generate underground.)
• Witch Huts (Witches will generate.)
• Igloos (Underground basement will generate.)

Another unique part about the flat generation is that biome bleding generates in chunks, so you can easily find chunk borders!

This pack works on all MC versions above 1.17 including betas.
Following experimental features are needed for the pack to work!

If you want to see some of the new flat terrain, take a look at the screenshots provided below.

• Trees can rarely generate cut off from side.
• Random blocks of water rarely generate above oceans.
