Can i still use Assets which not longer available on the Asset Store in my Project?

I have buy a asset from the asset store a year ago which is now not longer available.

Can i still use it in my projects?

If it was deprecated because the publisher is no longer selling it or supporting it, yes.

If it was removed by Unity because of copyright violation (such as artwork stolen from another artist), then no.

If you can still download it from the Asset Store window’s “My Assets” section, then it was probably just deprecated because the publisher is no longer selling it, but you can still use it in your projects.

Alright thank you
