Selling and using my assets

Hi, the question may seem strange. I want to sell my assets in the market, but I just have a small problem. The fact is that I am making a game on a completely different engine, can I sell assets on the marketplace and use them in my game at the same time?

It doesn’t matter what you’re doing with your own game. Also, let’s say you’ve got a 3D model you want to sell, you can adapt it to sell in both the Unreal Engine and Unity asset stores.
