We've been testing these features and doing some initial work on the first 5 chapters. Our goal is to roll out these updates in stages on the public-beta branch. Once testing is complete, we will move the update to the mainline for everyone to check out!

Peer Review 📝

To recap, this update will:

  • Fix minor bugs, visual errors, and improve asset optimizations where possible

  • Add improved parallax-corrected cubemap reflections

  • Improve outdoor baked lighting and leverage new image-based sky lighting

  • Improve indoor baked lighting (better static prop lighting and bounce lighting overall)

  • Improve real-time Cascaded Shadow Map (CSM) lighting

  • Deliver significantly better performance across the game

Here are a few early examples:

These effects are subtle by design, but they still add a noticeable amount of depth. When we went back to capture some comparison shots, something felt missing without the new parallax cube maps and the new lighting. We're excited to get this in the hands of the public!

Thank you, as always, to our wonderful community for your continued support. We'll be back soon™ with more updates and the first public beta.

See you in the Test Chamber!
