Hi guys, I am new here so sorry if this is the wrong place to ask.
I am planning to hire a 3D artist to model and texture the characters i have designed for my game. I have contacted the artist by phone and we have agreed on the price. But i want to make sure legally I am allowed to resell the 3D models (on unity asset store), since our team have very limited budget and we want to make every penny worth it.
So my question is how do I make sure that I own the 3D model and am able to sell it when needed? Do i need to use a third party site to legally prove that i have purchased all rights of the models?
