  • Fix errors in brush event logic that caused OnBrushEnter/Move/Exit to be called at incorrect times with invalid targets, resulting in crashes when editing prefabs with multiple meshes with different shaders
  • Fix undo throwing errors when splat_cache is null.
  • Clamp radius max value to min+.001 to avoid crashes when scrolling radius shortcut with equal min/max values.
