Unreal Engine incompatibility notice

Good afternoon.
I’d really like it to be clear when purchasing models that a given product is incompatible with Unreal Engine.
Because it’s a very unpleasant situation when you buy an FBX model, and it can’t even be imported because it’s incompatible. Or the animation doesn’t work, and so on.
And it’s not even about the money, since it might only work in other editors. It’s about the time spent. When you need the prop now, you’re wasting time reworking it or generally looking for a solution.
