In this tutorial we will show you how to generate an image based on a Python script using the great Blender 3D application.
This will allow you to automatically have an up-to-date image available for your users just by pushing your Python script.

Go to My repositories / Create and create a private repository named blendergraph.

Go to Settings / Webhooks / Add to add a webhook. This is the way your code will be run and will generate the image when you push into your repository.
Set repository filter to blendergraph, add a description, select Push as the trigger event, select fedora-32-x86_64 as the environment, add blender to the packages section and set the first command to be make; then press Add button.
Now, this hook will be executed at your next push.

Clone the main blendergraph repository: And change the origin remote to yours:
Look around in the repository, especially in the Makefile and rocketgit/artifacts files. You will see that the Makefile is generating .png and .blend files from the .py files. The artifacts file collects all .png and .blend files and uploads them in a directory with the name of the push branched file (we are using @@refname_short@@ variable.

We are ready to do our first push:
After few minutes, if you check your Artifacts area of your repository, you should see the folder main and, inside it, the .png and .blend files, with the correct content type.
You can click the .png file and look at it.
If the artifacts are not there, check your webhook and see the last output. It allows you to debug what went wrong.

As an exercise, change something in the .py file, commit and push. You will see after few minutes your newly generated image.
