Cómo crear extensiones#

Creating an extension takes only a few steps:

  1. Open the directory containing the add-on code or theme file.

  2. Add a blender_manifest.toml file with all the required meta-data (name, maintainer, ...).

  3. Use the Blender command-line tool to build the extension .zip file.

Cómo publicar en la Plataforma de Extensiones de Blender:

The extension will be held for review, and published once the moderation team approves it.

Archivos de extensiones#

An extension is shared as a .zip archive containing a manifest file and other files. The expected files depend on the extension type.

Extensiones de tipo Complemento#

Add-ons need at least the manifest and an __init__.py file, while more complex add-ons have a few different .py files or wheels together.

my_extension-0.0.1.zip
├─ __init__.py
├─ blender_manifest.toml
└─ (...)

Extensiones de tipo Tema#

A theme extension only needs the manifest and the .xml theme file.

my_extension-0.0.1.zip
├─ blender_manifest.toml
└─ theme.xml

Nota

Extensions can optionally have all its files inside a folder (inside the archive). This is a common behavior when saving a repository as ZIP from version-control platforms.

Manifiesto#

A manifest is a file with all the meta-data required for an extension to be processed. This example is a good starting point to the blender_manifest.toml that should be inside the .zip.

schema_version = "1.0.0"

# Example of manifest file for a Blender extension
# Change the values according to your extension
id = "my_example_extension"
version = "1.0.0"
name = "My Example Extension"
tagline = "This is another extension"
maintainer = "Developer name <[email protected]>"
# Supported types: "add-on", "theme"
type = "add-on"

# # Optional: link to documentation, support, source files, etc
# website = "https://extensions.blender.org/add-ons/my-example-package/"

# # Optional: tag list defined by Blender and server, see:

Línea de comandos#

Extensions can be built, validated & installed via command-line.

To build the package defined in the current directory use the following commands:

blender --command extension build

See build docs.

—

To validate the manifest without building the package:

blender --command extension validate

You may also validate a package without having to extract it first.

blender --command extension validate add-on-package.zip

See validate docs.
