You can use it in any type of project you want, may it be commercial or non-commercial :D . Though credit is not necessary, it would be highly appreciated. :D
So is it CC0?
If yes, you should add the license into metadata for the asset packs:
"Edit asset pack->Metadata->Release Info->License for assets" It will increase the size of audience that will be able to find your art
Oh okay. Thanks for the note I will update the asset pack accordingly :D!
