There are many problems with editing both Prefab assets and Prefab instances at the same time.
There are many problems with editing both Prefab assets and Prefab instances at the same time.
In the Unity System, edits in a Prefab instance with a Prefab asset only have change points. In this case, if polygons are deleted or recreated on the Prefab instance, synchronizing it with the original Prefab asset may cause problems.
The mesh is empty in the case of Prefab assets.
In the current UModeler Prefab system, there is no existing mesh in the Mesh Filter, and meshes are created by placing Prefab instances in a scene, defeating the purpose of the original intention of the Prefab feature.
In this case, as more Prefab instances are placed, the number of meshes increases, wasting additional storage and memory.
Prefab instances have meshes created in the scene.
A second instance creates a mesh that is different from the first.
The changed workflow does not permit UModeler modeling-related edits, except on the Prefab Editor.
If a Prefab instance is selected in Scene View, users are provided with an Open Prefab Editor button, which leads to the Prefab Editor; an Open Regular Prefab Editor button; and an Unpack Prefab button, which unpacks prefabs.
The improved Prefab workflow will immediately add a mesh created on the UModeler to the Prefab asset.
Most UModeler features can be used on the accessed Prefab Editor, enabling modeling. However, the following features cannot be used.
Versions after 2021.2 enable editing as it is placed in the scene (In Context Mode (link)) by clicking on the Open Prefab Editor in the Prefab instance.
Although In Context mode is supported in versions of Unity from 2020.1 to 2020.2, it cannot be accessed through the button provided by Umodeler. To use this feature, click on the Prefab Open button at the top of the Inspector window.
The UModelerize feature is not permitted on Prefab assets or Prefab instances.
