## Contributing
We welcome contributions! You can contribute in many ways:
- **Contribute code to this repository** - We welcome code contributions. More guidelines coming soon.
- **Contribute procedural generators** - `infinigen/nodes/node_transpiler/dev_script.py` provides tools to convert artist-friendly [Blender Nodes](https://docs.blender.org/manual/en/2.79/render/blender_render/materials/nodes/introduction.html) into python code. Tutorials and guidelines coming soon.
- **Contribute pre-generated data** - Anyone can contribute their computing power to create data and share it with the community. Please stay tuned for a repository of pre-generated data.
### Getting Help
Please post this repository's Github Issues page for help. Please run your command with `--debug`, and let us know:
- What is your computing setup, including OS version, CPU, RAM, GPU(s) and any drivers?
- What version of the code are you using (link a commit hash), and what if any modifications have you made (new configs, code edits)
- What exact command did you run?
- What were the output logs of the command you ran?
- If using `manage_jobs`, look in `outputs/MYJOB/MYSEED/logs/` to find the right one.
- What was the exact python error and stacktrace, if applicable?
