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 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?

Acknowledgements

Infinigen wouldn't be possible without the fantastic work of the Blender Foundation and it's open-source contributors. Infinigen uses many open source projects, with special thanks to Land-Lab, BlenderProc Blender-FLIP-Fluids and Blender-Differential-Growth.

We thank Thomas Kole for providing procedural clouds and Pedro P. Lopes for the autoexposure nodegraph.

We learned tremendously from online tutorials of Andrew Price, Artisans of Vaul, Bad Normals, Blender Tutorial Channel, blenderbitesize, Blendini, Bradley Animation, CGCookie, CGRogue, Creative Shrimp, CrowdRender, Dr. Blender, HEY Pictures, Ian Hubert, Kev Binge, Lance Phan, MaxEdge, Mr. Cheebs, PixelicaCG, Polyfjord, Robbie Tilton, Ryan King Art, Sam Bowman and yogigraphics. These tutorials provided procedural generators for our early experimentation and served as inspiration for our own implementations in the official release of Infinigen. They are acknowledged in file header comments where applicable.

Infinigen has evolved significantly since the version described in our CVPR paper. It now features some procedural code obtained from the internet under CC-0 licenses, which are marked with code comments where applicable - no such code was present in the system for the CVPR version.
