Project-Regon⛰️ 4.0 — World Features Update

Finally, a new Project-Regon update is here!
4.0-dev-01 is the World Features Update, and it is one of the biggest changes to Regon's environments so far. This update focuses on making the world feel much more natural, varied and alive, with completely new trees, vegetation, fallen logs, rocks, springs and many smaller details across the world.
Instead of changing the terrain itself, 4.0 builds on top of Regon's existing landscapes and gives the different biomes much more of their own identity.
