Commit: c77597cd0e15f9d7b6f963593b545cc94950eb8d Author: Hans Goudey Date: Tue Mar 8 12:16:20 2022 -0600 Branches: blender-v3.1-release https://developer.blender.org/rBc77597cd0e15f9d7b6f963593b545cc94950eb8d
Fix T95843: Invalid mesh runtime data after sculpt undo When the geometry of the sculpt mesh was replaced when restoring from a full undo step, the runtime data was not cleared (including any normals, triangulation data, or any other cached derived data). In the report, only the invalid normals were observed. The fix is to simply clear these caches. Later they will be reallocated and recalculated if necessary. Since the whole mesh replaced here anyway, this should be a safe fix.
