dungeon-pipeline

An OS-agnostic, portable, extensible 3D pipeline for the BYU Center for Animation's 2025 Capstone film, Love & Dungeons.

dungeon-pipeline is currently being used on EL8 and Windows 10 systems. It should also be functional on macOS systems, but that has not been tested.

Setting up a copy of dungeon-pipeline

1. Fork this repo and clone it to the production location.
2. Create an pipeline/env.py file following the specifications in pipeline/env.py.md. This will get things like ShotGrid auth set up, and provide OS-specific DCC executable paths.
3. Install needed python libraries into pipeline/lib/python/any. (This will soon by managed via Poetry (Issue #137), for now see the list in .githooks/setup-venv.sh).
4. Clone branches for development locally, copy over the env files and get to work!

Setting up a dev environment in the labs

1. Generate a GitHub SSH key and upload it to your GitHub

   • ssh-keygen -t ed25519 -C "yourgithubemail@email.com"
     cat ~/.ssh/github.pub

   • When it asks for a path, type '/users/animation/yournetid/.ssh/github'
   • Only provide a passphrase if you want to type that every time you push or pull
   • Go to https://github.com/settings/keys and add the contents of ~/.ssh/github.pub as a New SSH key
2. Make a local copy of the git repo

   cd ~/Documents
   git clone --recurse-submodules -c core.sshCommand='ssh -i ~/.ssh/github' git@github.com:scottdmilner/dungeon-pipeline.git
   cd dungeon-pipeline

3. Configure the git repo to use the new SSH key and our git hooks

   git config --add --local core.sshCommand 'ssh -i ~/.ssh/github'
   git config --local core.hooksPath .githooks/

4. Check out a dev branch for the feature you are working on (or create a general dev branch (yourname-dev))

   git checkout -B feature-name-yourname 
   # don't need -B if it already exists
   git push --set-upstream origin feature-name-yourname

Code Style

For this project, we are using the Black style of Python formatting. There is a Git pre-commit hook that will automatically run the ruff formatter on your code whenever you make a commit. If it changes any of your formatting it will print a message that looks like this:

Formatting with ruff...
3 files reformatted, 12 files left unchanged

After that, you can amend your commit to include the changes that ruff made with

git add <changed files here>
git commit --amend

This should generally be avoided, but if you need to override the Black style for some reason, use the following comments to suppress ruff:

...
# fmt: off
unformatted code here
# fmt: on
...
