Latest issues
- Flickering bright white dots in the Scene when the Android Platform is selected and DX11 Graphics API is used with Iris(R) Xe Graphics GPU
- Inconsistent capitalization and misaligned text in multiple query blocks in Search window
- “Remove Unused Overrides” available on not loaded Scene and throws “ArgumentException: The scene is not loaded” warning
- Adaptive Probe Volume occlusion edge is calculated incorrectly when viewing probes near geometry edges
- WebGL sends wrong value with large numbers when SendMessage function is used
Resolution Note:
The probe structure is not automatically updated when using Additive scene loading or async unloading for performance reasons. Please see the documentation page for probes and scene loading: https://docs.unity3d.com/2022.3/Documentation/Manual/light-probes-and-scene-loading.html
In order for the probes to be properly loaded and unloaded LightProbes.Tetrahedralize() or LightProbes.TetrahedralizeAsync() must be used.
