Welcome, I want to ask about these things. I liked it very much, about the brushes that are purchased. They are ATN and ABR. Is it made by the author who offered to buy, or can others buy it and work on it and then sell it? I want to help ?
If they’re selling it, then legally it should all be made by them. Plus, it looks like this is a Photoshop Action, which is what an ATN file is, the ABR file is the brush(es) that are used in the action. So you’re basically asking if you can take someone’s item, make some changes, then resell it, which is a big definite NO.
Thank You My Friend
