Asset Catalogs help you to organize your assets. They look a little bit like file directories, but they are completely independent of the location of your blend-files. Assign each asset in a blend-file to its own catalog, or have one big catalog with all the assets of all the blend-files combined. It’s all up to you.
Similar to Colecciones, catalogs can be nested i.e. you can have a main catalog that contains several nested catalogs. For example, this allows you to have a catalog of assets for «Furniture» with sub-catalogs of «Tables», «Chairs», «Lamps», etc…
For more technical information, see Asset Catalogs on the Blender Wiki.
The Home Location of Assets
There can be as many catalogs as you want, but an asset can be assigned to a single catalog at a time. This is similar to a file system, where a file is only in one directory (ignoring advanced things like symbolic links).
Catalogs themselves can be nested and moved by dragging and dropping. Moving a catalog will not modify the assets it contains; they will simply move along to the new location of the catalog.
Selecting a catalog in the Asset Browser will show all assets in that catalog and in child catalogs.
So, in the preceding example, selecting
Characters/Ellie/Poses will also show assets from
Assigning an Asset
To assign assets to a catalog, just select and drag the assets on top of the catalog.
You can assign an asset to the «Unassigned» catalog, this will remove it from any existing catalogs.

Each catalog consists of a catalog path, a UUID, and a simple name. Normally you would only deal with the catalog path; the rest is for internal Blender use and/or for emergency situations.
The path of a catalog determines where in the catalog hierarchy the catalog is shown.
which would result in the following catalog tree.
The highlighted catalog has path
Each catalog has a UUID, which is normally hidden from the user interface (enable Developer Extras and the experimental Asset Debug Info option to see them). This is what is stored in the asset, and what determines the «identity» of the catalog. As a result, a catalog can be renamed or moved around (i.e. you can change its path), and all assets that are contained in it will move along with it. This only requires a change to the catalog itself, and not to any asset blend-file.
Each catalog has an optional simple name. This name is stored along with the UUID in each asset. The purpose is to make it possible for humans to recognize the catalog the asset was assigned to, even when the catalog definition file (see below) is lost.
Like the UUID, the simple name is normally hidden from the user interface. Enable Developer Extras in the interface preferences to make it visible in the Asset Browser.
Catalog Definition Files
Asset catalogs are stored in Catalog Definition Files (CDFs). Blender 3.0 supports a single CDF per asset library.
It is stored in
blender_assets.cats.txt in the root directory of the asset library. If the file does not exist,
Blender will create it when the catalogs are saved. When catalogs are changed, Blender updates that file, but also
creates a backup of the previous state to a file named
Which File to Write To
Asset catalogs can be saved independently of the blend-file; the catalog editor has its own «Save» button.
Catalog Definition Files (CDFs) are relatively simple text files, encoded in UTF-8.
Each CDF consists of a version indicator, and a line of text per catalog.
Each catalog line is colon-separated, of the form
This is an example of a valid catalog definition file:
# This is an Asset Catalog Definition file for Blender. # # Empty lines and lines starting with `#` will be ignored. # The first non-ignored line should be the version indicator. # Subsequent lines are of the format "CATALOG_UUID:catalog/path/for/assets:simple catalog name" VERSION 1 313ea471-7c81-4de6-af81-fb04c3535d0e:catalog/without/simple/name: ee9c7b60-02f1-4058-bed6-539b8d2a6d34:character/Ellie/poselib:character-Ellie-poselib cd66bf52-58f4-45cb-a4e2-dc0e0ee8f3fe:character/Ellie/poselib:character-Ellie 4eb44ec6-3424-405b-9782-ca006953e799:character/Ellie/poselib/white space:character-Ellie-poselib-white space b63ed357-2511-4b96-8728-1b5a7093824c:character/Ružena/poselib:Ružena pose library dcdee4df-926e-4d72-b995-33106983bb9a:character/Ružena/poselib/face:Ružena face fb698f2e-9e2b-4146-a539-3af292d44899:character/Ružena/poselib/hand:Ružena hands
Valid Catalog Paths
Catalog paths follow the following rules:
All paths are absolute; there is no difference between
/as separator (no
\; think less filesystem path and more URL).
Not empty (it’s required for a valid catalog).
No empty components (so not
Paths are always interpreted as UTF-8.
