Latest issues
- Unity Cloud icon does not appear next to project and does not connect correctly when the project is created with Cloud but closed right after creation
- ScrollerSlider in the Scroller Control is still using UXMLTraits
- Crash on ExtractHandles when shutting down the Editor in a specific scene while Burst jobs are in progress
- Unity Hub closes with no "Project is currently open" window when selecting an already open project from the Projects list
- The Hub freezes indefinitely when copy/pasting a lot of characters in the “Set project display name” Hub window since it has no character limit
Resolution Note:
The vertex painting tool in the project is applying color values directly to the MeshFilter's shared mesh. ProBuilder by design overwrites the values on that mesh, meaning any modifications made to the mesh will be lost. See the Scripting API Overview for more information on why https://docs.unity3d.com/Packages/com.unity.probuilder@4.0/manual/api.html.
To apply vertex colors on a ProBuilder created mesh, you should set the `colors` property on the `ProBuilderMesh` component. See https://docs.unity3d.com/Packages/com.unity.probuilder@4.0/api/UnityEngine.ProBuilder.ProBuilderMesh.html#UnityEngine_ProBuilder_ProBuilderMesh_colors
