Hello! Yes, it is CC0.
In this case you should add the license into metadata for the asset pack(s):
"Edit asset pack->Metadata->Release Info->License for assets" It will increase the size of audience that will be able to find your art
Okey. Thanks for help :)
I also noticed Blender tag. If you made it with blender, you can also add it to metadata "Edit asset pack -> Metadata -> Engines & tools"
