When I create a duplicate linked object model in object mode most of its characteristics should be duplicated including the meshes of both. When I go into edit mode the two objects should show their meshes at the same time. When I try this, only the original mesh is highlighted. Why are not both meshes being shown in edit mode? This used to be the default behavior in Blender as shown at 3:02 in this video: https://youtu.be/ENdGhAM3NzA?t=182
Two part answer:
- When you duplicate an object, the data that is duplicated is configurable in Preferences, under the Editing tab. Here are the defaults for 3.2:
- When you go into edit mode, the two object do not show their meshes at the same time as you have discovered. This is a user interface design choice by the developers. While an edit updates both meshes in real time, only the active mesh is shown. This is to reduce confusion in the interface.
