Vray for unreal

I was just on the market place, and browse all free for the month and came across Vray for unreal, and check it out, that is beyond awesome, then notice monthly and yearly prices in Euro, and i was thinking if this in free section why asking for price, but also free trial pack, can someone can clarify it, as its in free for month, and i decided to download it, after the free for the month will then be paying yearly prices in Euros?

Yes, after the trial you would need to pay the subscription fee to continue using it

Thank you darthviper107 for your reply. And how are you coping with the Unreal engine.
