Geophilic
By bebebea_loste (also responsible for Explorify) — described as “a subtle-ish overhaul of vanilla Overworld biomes.” Rather than adding wholly new biomes the way Regions Unexplored does, Geophilic reworks the look and feel of existing vanilla biomes for more visual variety on the ground, aiming to stay recognizably vanilla rather than exotic. No server-side config override is present.
