Well, you can refer this to the copyright forum if you like. Whether something took hours to make or two minutes to make is totally irrelevant. If you make a SCENE you have copyright on the SCENE (the .vue file). If you make a RENDER you have copyright on the RENDER (the .jpg file). estherau's example is a fair one. You can't redistribute a copyrighted font file without permission. But you certainly can distribute anything you like that uses that font as long as you don't distribute the actual font file. The only exception would be in the case of something that was trademarked.
