Sell 3d model with Substance Painter materials

Hello, I created a axe in blender and textured it in Substance painter with the materials which are included. When I want to sell the axe do I have to make my own materials or can I use the included materials.

This is more a question to be made on the Substance Painter forums than here, however:

THIS IS NOT LEGAL ADVICE, AND IS PURELY OPINION ===============================
From my understanding of the license from substance painter the material resulting of the usage of the base materials included on the substance painter are there for you to use them in creating unique materials for your assets, therefore, “the material”, as the textures resulting of using substance painter are “made” by you and are unique to your model, so you should be fine.

Please take the time to read the Substance Painter EULA and/or consult on their respective forums.
