Make sure to check out the What's new for artists and designers in Unity 2021.2 blog post for a complete list of features. Enlighten Realtime Global Illumination This feature was implemented by: @KEngelstoft This feature enables Unity creators to enrich their projects with indirect lighting that responds to real time changes in light and material properties. Interactive visual feedback makes it possible to significantly reduce lighting design iteration times. In the 2021.2 release we have re-enabled support for Enlighten Realtime Global Illumination in HDRP and the Built-In Render Pipeline, and added support to URP. We've also extended support for Enlighten Realtime Global Illumination to the Apple silicon, PS5, and XSX platforms. Progressive GPU Lightmapper Tiling This feature was implemented by: @ADufay This new feature makes it possible for users to utilize the Progressive GPU Lightmapper for faster bakes at larger lightmap resolutions. The tiling technique helps reduce GPU memory requirements by breaking down lightmaps into tiles sized to match the amount of GPU memory available. This feature reduces the risk of the GPU lightmapper running out of memory and falling back to the CPU. It activates automatically, requiring no input from the user. Note that tiled denoising has not been implemented yet. Certain denoising configurations can still cause out of memory issues. We are working on it. Lightmap Compression in the Lighting Settings Asset This feature was developed by: @rasmusn and @Pema-Malling This improvement introduces a Lightmap Compression property in the LSA. This replaces the previous Compress Lightmaps checkbox. As a result, lightmap compression quality is no longer tied to Lightmap Encoding project setting. Instead, generated lightmap textures derive their compression quality from this drop-down. You can access Lightmap Compression drop-down in the Lighting window. There are four options available: None Low Quality Normal Quality High Quality Each setting will result in an appropriate texture compression quality setting. You can verify this in the texture importer settings. High Quality setting is chosen by default for new and upgraded projects. Feature access & feedback You can get access to the feature by downloading the latest 2021.2 build via the Unity Hub, or via this link. We are looking forward to hearing your feedback!
