Size restriction for trees is now 96 blocks long which allow to use big trees. #### Caves Ouranos has 3 differents cave systems: * "Vanilla like" caves that look like the vanilla caves * Water caves are massive caves where water is flowing * Lava caves are in depth caves with lava flowing Each cave can be disabled independently in the configuration file #### Rivers Ouranos has a river system that evolved compared to Stratos to remove non-natural behaviours #### Dungeons Ouranos implements custom dungeon system. #### Structures Ouranos has a complex structure system that allow you to add npcs/mobs into your structures #### Villages and cities Ouranos implements procedural villages and cities system.
