INSTALLATION

UNINSTALL OLD VERSION

Navigate to the add-ons menu in Blender at Edit > Preferences > Add-ons
In the top-right search window, search for Roblox
If Upload to Roblox is present, click the left arrow to expand it and click Remove to uninstall it
Restart Blender after uninstalling

INSTALL NEW VERSION

Prerequisite: Blender version 3.2 or greater is required

Be sure to uninstall any old version first, including restarting Blender afterward
Download the latest add-on zip file from the repository releases page
Navigate to the add-ons menu in Blender at Edit > Preferences > Add-ons
Click Install
Select the zip file downloaded above and click Install Add-on (Do not unzip the file!)
In the top-right search window, search for Roblox
Find the Import-Export: Upload to Roblox add-on in the list, and ensure the checkbox next to its name is checked
Open the plugin's main panel by going to a 3D window, pressing N, and selecting the Roblox tab
Click Install Dependencies. This is only required the first time the plugin runs
Once it says Installation complete!, restart Blender
The plugin is now ready for use

USAGE GUIDE

LOG IN

Be sure to complete the installation steps, including dependency installation and restarting Blender
Open the plugin's main panel by going to a 3D window, pressing N, and selecting the Roblox tab
Click Log in
Unless previously logged in, your browser opens and prompts for authorization
In your browser, authorize creators to use in the plugin. To do this, log into your Roblox account. Then, select the account and/or groups you want to upload with. Click CONTINUE at the bottom of the page, then click CONFIRM AND GIVE ACCESS. Your browser should indicate a successful login. You can close the page and return to Blender
Select the desired creator from the Upload to: dropdown of authorized creators

UPLOAD

Select any number of meshes or collections you want to publish at once. Each selected object will be uploaded as its own asset. If you want to publish multiple objects as a single asset, group them into a Collection and select the Collection
Click Upload
Open Roblox Studio and search for your object under Home > Toolbox > Inventory (tab) > My Packages (dropdown) This list is currently unordered, you can use Search to find it by the name matching the object name in Blender

ASSET VERSIONING & AUTO-UPDATING CHANGES

Since objects are uploaded as packages, we can take advantage of package behavior to automatically pull in changes when you publish a new version of the package.

In Roblox Studio, after inserting the package into your hierarchy, select the PackageLink object inside the package
Ensure the AutoUpdate property of the PackageLink is checked
When a new version of this object is uploaded from Blender, this package will automatically update to the latest version, overwriting any modifications
This package association is tracked in Blender under the Custom Properties of an object or collection, where it stores the Roblox Package ID
To upload a previously-published asset to a new asset ID instead of uploading as a new version, delete this Roblox Package ID custom property

CONTRIBUTING

Roblox is providing this plugin source as a reference implementation. Our goal is to illustrate how Open Cloud APIs can be used to create integrations with external tools.

Our hope is the community leverages this reference implementation to build their own tools and extensions. We actively encourage anybody who wishes to extend this reference implementation with new features to fork this repository and share their work with the community.

As such, we will not be accepting Pull Requests that introduce new features or functionality. However, in the interests of ensuring this plugin remains a functional reference implementation, we will be accepting Pull Requests for bug fixes.

RUNNING FROM SOURCE CODE

Do either of the following options to install the plugin:

OPTION 1: RECOMMENDED VS CODE DEVELOPMENT WORKFLOW

This option allows you to quickly iterate on the codebase and reload the plugin for testing changes, as well as use a debugger during development.

Be sure to uninstall any plugin zip file first, and then close Blender
Open VS Code as administrator to allow the Blender Development plugin to install a debugger for Blender (Only need to do this the first time)
Install the VS Code extension JacquesLucke.blender-development
Open the repository in VS Code
Open the command window (ctrl/⌘ + shift + p)
Run the > Blender: Build and Start command
Select your Blender executable file
The plugin is now running in Blender with a debugger attached
If saving a file does not auto-reload the plugin, you can manually reload the plugin with > Blender: Reload Addons

OPTION 2: INSTALL MANUALLY

Zip the top-level repository folder such that the first level inside the zipped folder is another single folder containing everything
Follow the steps to install a new version using this zipped folder instead of the one from the releases page

PULL REQUESTS

Before marking your pull request as ready for review, please ensure:

Your pull request does not introduce new features or functionality
All python files are formatted with black and the CI format check is passing
Any dependency changes are reflected in requirements.txt
All commit messages are complete and informative
Your Pull Request includes a description of the bug and how your changes fix the bug

CONTINUOUS INTEGRATION CHECKS

Github Actions is set to check that formatting matches black formatting before allowing a merge to main. Be sure to format your python code with black before pushing to avoid being blocked. You can use the VS Code plugin Black Formatter by Microsoft, or run the command line tool by installing it via pip install black and then running black .

CREATING A RELEASE

Releases are set up to automatically generate via Github Actions when a tag is added to a commit with the format v[0-9]+.[0-9]+.[0-9]+. For example, you can create a release from a commit with SHA a1b2c3d by doing the following:

git tag -a v0.0.0 a1b2c3d -m "My message for v0.0.0"

Or, tag the latest commit with:

git tag -a v0.0.0 HEAD -m "My message for v0.0.0"

where v0.0.0 represents a semantic versioning naming scheme v[major].[minor].[patch]
where [major] gets bumped for non-backward compatible changes,
where [minor] gets bumped for backward-compatible features,
and where [patch] gets bumped for backward-compatible fixes.

Once you've created your tag, push it to the repository with

git push --tags

PLUGIN VERSIONING

The plugin version is automatically updated by a Github Actions workflow to correspond with the committed version tag name (as described in Creating a Release). The version doesn't get committed to the codebase, so if you run the plugin locally instead of using a release, your plugin will just show the default version number that exists in the codebase.
