This sends a horrible message to people making content. He is attempting to make his own truck, whether it be a clone of one you uploaded or one he put together himself. You released it to the public, he has no restriction stating he cab't make his own truck from it. You should be glad someone is attempting to make good content, rather than try to dissuade them from making something at all. Why not take it as a compliment that he bases his work off your content? What is actually wrong with that?
@monsterjam16' I am very happy to see you are attempting to make content. If Blaise has a problem with you cloning his work, I give you fill permission to take anything I have made and turn it into your own. Keep up the good work!
