Engine v5.2.25
August 14, 2026
A patch in the Lume line.
what's new
- Big worlds with lots of detailed scenery run noticeably smoother while you walk around — the engine now remembers collision shapes it has already built instead of rebuilding them from scratch every time objects stream in or toggle their physics.
- Behind-the-scenes: when something goes wrong in a game, the team can now see exactly which engine version it happened on — fixes land faster.
- Fixed a bug where things your scripts built could come back invisible after a server hiccup — and stay invisible no matter what. The world now heals them on its own, and re-running the script that built them fixes them too.
- Savi now hears loudly when a script's changes applied live but nothing reached the saved game — instead of discovering it after a reload wipes the work.
