Epic Terrain Compatible

This is an official version! But I can't guarantee that updating the world to the official version or leaving the official version is 100% safe. Make a backup!

Contents:

• New basic terrain generation algorithm: Link the temperature, humidity, continentality, and erosion related to the terrain to achieve more reasonable terrain.
• New terrain erosion algorithm, erosion is more reasonable. Mountains and circular passes are realized.
• There are large and small rivers in rivers, and in this version the drop river is removed.
• Added the function of underground rivers, large rivers will generate underground rivers when they encounter mountains.
• Increases surface roughness, enriches texture details, and reduces excessive unreasonable smoothing.
• New coastlines: can form erosion and indentation coasts, Mediterranean Seas, straits, islands, peninsulas.
• Special Terrain: 1)Jungle (jungle, bamboo forest and other tree species are the same community),Its topographic content includes: small cliffs, stepped cliffs, steep slopes, small waterfalls, mesas, rich detailed terrain. 2)Desert,Its topographic content includes: simulated sand dunes.
• Cave modifications: 1)noise large caves only spawn on mountains, and small caves only spawn in flat and lower areas (the purpose is to avoid large pits on flat terrain). 2)Enhanced the smoothness of the cave terrain, which will be a little more gentle (the purpose is to go down layer by layer like a dungeon). 3)Added underground terrain and spawned magma rivers.
