The highly anticipated Once Human update April 24 is set to transform the game’s visuals in ways we haven’t seen since launch. This isn’t just another minor patch – it’s a complete reimagining of the game’s lighting system and a massive reward giveaway to celebrate the mobile version’s release.

Once Human Update: VVGI Technology Explained
At the heart of the Once Human Update April 24 is the introduction of VVGI (Vivid Global Illumination), a proprietary lighting system that pushes beyond traditional rendering techniques. Unlike standard implementations that either rely on pre-baked lighting (which can’t react to changes) or hardware-intensive ray tracing, VVGI offers the best of both worlds:
- Instant lighting reactions when you modify environments – break down a wall or place a new light source, and the illumination updates without delay
- True 24-hour cycle integration where sunlight transitions affect not just brightness but also color temperature and shadow direction, realistically
- Weather-adaptive effect, where rain produces cooler, diffused lighting while sandstorms create atmospheric haze
- Smart occlusion detection using machine learning to automatically identify indoor/outdoor spaces, eliminating unnatural light leaks


What makes this especially impressive is how efficiently it runs. The development team managed to compress what would normally be 45GB of lighting data down to just 800MB through neural network optimization. This means you get next-gen visuals without needing next-gen hardware.

Once Human Update: Quality of Life Improvements and New Content
Beyond the headline graphics overhaul, the Once Human Update brings several important refinements:
- Server naming conventions have been simplified to make it easier for new players to identify suitable worlds. (April 17)
- Critical bug fixes address issues with the purification system and specific weapons like the Mr. Wish rocket launcher.
- Performance optimizations ensure the visual upgrades don’t come at the cost of smooth gameplay.

Perhaps most exciting is the developers’ confirmation that they’ve solved the long-standing discrepancy between how characters look in the creation screen versus in-game. While this particular improvement won’t arrive until a future update, it demonstrates the team’s commitment to polishing every aspect of the experience.
For returning players, the update offers compelling reasons to revisit the wasteland. For newcomers, there’s never been a better time to start your survival journey. And for everyone, those free rewards provide plenty of incentive to log in when the patch goes live.
Why This Once Human Update is Huge
The Once Human Update April 24 represents more than just technical improvements – it shows how seriously the developers are listening to community feedback. Many of these enhancements directly address player requests, particularly regarding lighting quality and character visuals. With the mobile version launching simultaneously, this is designed to be a major milestone for the game’s evolution.
