Hello! The license states "You may not resell or redistribute the assets themselves, as-is or re-exported, as an asset pack." Does that mean if they are used in an open source project, they cannot be included in the public GitHub repository?
Hi! Since the pack is free, I’m pretty flexible.
Ideally, it's best to keep the raw files out of the public repo (via .gitignore or by linking back to the original page) so people don't just grab the full pack directly from your code.
That said, if having the assets right in the public repository is necessary for your project to build and run, go ahead! Just throw a quick note in your README mentioning that the assets belong to their original license and aren't covered by your project's open-source license.
Good luck with your project!
