Legal concerns regarding the use of rendered Fab assets from Unreal Engine as source material for AI-generated videos

Hi it is much faster to use fab assets as backgroundimages for consistente backgrounds than wasting lots of money for ai background inconsistency (e.g. higgsfiled.ai, kling,but the question is: Is this allowed… because we read no train ai.. i understand but technically a LORA system is kind of training… But i use it definitly only for my unreal engine game. Would me nice to get an answer von EPIC Games so we dont have to guess… thx
