Unity Pro or Unity Enterprise plans are required for businesses with revenue or funding greater than $200K in the last 12 months, and for those who do work with them. If you or your company’s revenue or funding is less than $200K in the last 12 months, you are eligible to use Unity Plus.

Students enrolled in an accredited educational institution of legal age to consent to the collection and processing of their personal information (e.g., age 13 in the US, 16 in the EU) are eligible to use the free Unity Student plan. Eligibility for small businesses is based on any revenues or funds raised in the past 12 months. Eligibility for individuals and hobbyists is based on revenues or funds in connection with the use of Unity. Until they add this, I'm afraid you'll have to search and ask for each asset.Individuals, hobbyists and small businesses that have less than $100K of revenue or funds raised in the prior 12 months are eligible to use Unity Personal. It's unfortunate that the Asset Store page does not provide a clear "license" section. I'm not exactly sure what license apply here, so I'll suggest you ask the author what are the terms of use of their asset before you commit to it.

If you get the SciFi Robots, you'll find no license on the Asset Store page, and no readme and no license.txt in the package.


If you get the Standard Assets provided by unity, you'll have to dig, find, read and understand the actual license, where there is no mention that you must credit the author If you get the "Unity-Chan!" Model, you'll have to display somewhere the "license logo or the license sign separately" as specified by the “Unity-Chan” License Terms and Conditions I'm assuming that by "free asset", you mean an asset available on the unity Asset Store that is shown when filtering by "free" ( resulting in something like this).
