Found one on the website, under ToS, but I don't quite understand this section:
You may not resell, redistribute, or sublicense the product as-is, either in its entirety or as a part of a larger work.
Does this simply mean I cannot redistribute the assets unless it's part of a separate project, or that I may not use them unless I somehow prevent others from accessing them in the project files? Would this work for an open-source project in which the files are included in the repo?
