 Secondly, the renderer was rewritten for higher efficiency and support for additional post-processing techniques, enabling up to 3,000 non-playable characters to be rendered in real time (compared to the few 100s in the previous Anvil engine).Finally, AnvilNext adds technology from "Far Cry 4" to support a more dynamic sandbox environment and new water technology, where the game world could change over time depending on player actions and progression.This means enemy settlements on both land and sea may appear/disappear relating to the events in the game, and water effects could be adjusted accordingly.
