How does any Redistribution work?

The answer is yes, if you have a commercial license and follow these rules:

1. You may not distribute our textures in any way meant to compete with us.
2. You may only distribute our textures on any asset store if they are packaged or are altered in such a way that the base material from our site is not able to be extracted in a meaningful and useful way. (i.e. unique UV sets on an asset or prop)
3. You may only release our textures if they are packaged in a game.
