Woah, slow down there - working on some basic features first before moving onto the more advanced stuff like how to handle monsters and such :)
Progress update:Worked on the terrain generation and foliage a bit. Mushrooms, flowers, grass, vines and trees now spawn on the terrain. Mushrooms only spawn in very dark caves, deep under the ground.
Custom tree importerTo create trees and easy variations I've written my own importer. The trees are modeled in Zoxel, then exported and imported into the converter which matches colors with node types. The trees can then be spawned in the world. I didn't go for MTS because of the flexibility I now have, I can add random shapes and make trees have random heights.
Zoxel + Voxus = TREES! :)
