So I read here and there that Core terrain uses this mind blowing plugin https://voxelplugin.com/#project-showcases for terrain creation. Would be great if we had a API to do dynamic stuff with terrains and maybe not just that (but in general with voxels). This would open possibilities for procedural world generation, destructible environments, and so on.
Maybe for starters we could have something similar to : Terrain . But sure Core can do better with this plugin.
