Let's assume that I am doing a 3D project for a client, among my models and assets I use a texture / image from the Internet marked as CC-0 license:
"The Creative Commons CC0 license gives you near limitless freedom to use the materials, models and other assets: You can copy, modify, distribute and perform the work, even for commercial purposes, all without asking permission."
https://creativecommons.org/publicdomain/zero/1.0/
I provide the client with a source file containing said texture. Of course it is only a small part of the overall project.
Is it okay in terms of a legal / licensing aspect?
