Kacper Szwajka, developer of the survival strategy game "Highland Keep," has released a new demo showcasing his terrain editing workflow. The game, set in medieval Scotland, blends third-person combat with RTS-style castle building. Szwajka has previously developed custom solutions for handling millions of scattered objects, terrain rendering, and animating thousands of characters simultaneously. Recent updates also highlight real-time voxelized lighting in "Highland Keep." Players can wishlist the game on Steam and follow its development on Twitter.
