  • Fixed an issue with SSGI adding an empty deferred renderer to builds.

[1.1.3] - 2024-11-23

Fixed

  • Fixed a shader compilation issue in Unity 2023.

[1.1.2] - 2024-11-12

Fixed

  • Fixed a compilation issue by disabling rendering layers in Unity 2023.1. The RenderingLayerMask was introduced in Unity 2023.3.

[1.1.1] - 2024-11-07

Added

  • Added a message to the volume override when the rendering debugger window is open.

Added

  • Added new fallback options and support for Adaptive Probe Volumes (APV):
    • Sky: Falls back to the sky ambient probe or APV.

Changed

  • Changed the default value of ray miss property from Reflection Probes to Reflection Probes and Sky.
  • Improved the quality of SSGI across different resolution scales.

[1.0.10] - 2024-09-05

Fixed

  • Fixed an issue where the SSGI quality did not match the volume override when denoising was disabled.

  • Improved SSGI performance by reducing arithmetic and texture sampling operations.

Fixed

  • Fixed an issue with incorrect depth precision on mobile platforms.
  • Fixed an issue where a temporary camera texture did not follow URP render scale.

  • Fixed an issue with SSGI on mobile devices.

[1.0.5] - 2024-08-01

Changed
