I installed Unity 2019.3.2 and a fresh install of A*, and when looking at the Hex / Terrain examples (might be more, I haven’t checked), whenever I run the scene I get the same four error messages repeating:
Not allowed to access vertices on mesh ‘’ (isReadable is false; Read/Write must be enabled in import settings) UnityEngine.Mesh:SetVertices(List`1) Pathfinding.Util.Builder:SubmitLines(RetainedGizmos, UInt64) (at Assets/AstarPathfindingProject/Utilities/RetainedGizmos.cs:205)
Not allowed to access triangles/indices on mesh ‘’ (isReadable is false; Read/Write must be enabled in import settings) UnityEngine.Mesh:SetTriangles(List`1, Int32) pathfinding.Util.Builder:SubmitLines(RetainedGizmos, UInt64) (at Assets/AstarPathfindingProject/Utilities/RetainedGizmos.cs:206)
Not allowed to access colors on mesh ‘’ (isReadable is false; Read/Write must be enabled in import settings) UnityEngine.Mesh:SetColors(List`1) Pathfinding.Util.Builder:SubmitLines(RetainedGizmos, UInt64) (at Assets/AstarPathfindingProject/Utilities/RetainedGizmos.cs:207)
Not allowed to access normals on mesh ‘’ (isReadable is false; Read/Write must be enabled in import settings) UnityEngine.Mesh:SetNormals(List`1) Pathfinding.Util.Builder:SubmitLines(RetainedGizmos, UInt64) (at Assets/AstarPathfindingProject/Utilities/RetainedGizmos.cs:208)
If I turn off that gizmo, the errors stop.
If I go back to Unity 2018.2.9, I don’t get these errors at all.
Is there something I need to change with A* if I’m going to use the newest Unity?
