## Manual Reparent from mesh_base to Graph


If you have a material inherited from the [mesh_base](../../../../content/materials/library/mesh_base/index.md) parent material and you want it to derive from a [graph-based](../../../../content/materials/graph/index.md) material, you need to make a reparenting.


> **Warning:** Before you start reparenting we strongly recommend you to make a backup of your projects or use a Version Control System.


If the names of parameters in the new base graph material are the same as in the old `mesh_base` all the previous values will be set for them automatically. Here is the list of the most common parameters that were used in the default `mesh_base` material:


> **Notice:** The parameters in your new base graph material must be named exactly like that (including the case) in order for reparent to work properly and keep parameter values.

There are the following ways to manually reparent a material:


- Use the [reparent feature](../../../../editor2/materials_settings/organizing_materials/index.md#reparent_material) in the *Materials* window of *UnigineEditor*. To reparent select the material(s) inherited from the `mesh_base` in the hierarchy and drag it with the left mouse button pressed to the desired graph-based material. ![](reparent.gif)
- The alternative way to reparent materials is via the ***Ctrl + P*** hotkey (first selected materials wll be reparented to the last one selected before the hotkey was pressed).


After reparenting the old materials are deleted and the new ones are created in place of them. Now you can freely rename the parameters in the newly reparented graph materials.


## Converting to Unique Graph


If you want to make some material inherited from `mesh_base` into a unique graph material at the top level of hierarchy, you must reparent it to some graph base material and then in the context menu (available on the right mouse click) select *Convert To Unique Graph*.

> **Warning:** In this case, the material will be turned into a default template material and **won't preserve previous parameters and any logic**. We are working on a smart conversion which must be available later.
