This is a question that I’d appreciate a direct answer from someone at Epic who knows for sure. I’m giving a conference talk in a few weeks on low-level rendering architectures, and I’d like to do a comparative analysis of an opengl renderer and a Metal renderer. Would using the renderers in Unreal Engine 4 be a breach of the license agreement? If there are constraints to what I can and can’t do, what are they? I know the license agreement talks about code snippets up to 30 lines in length. Is that the total amount of code? Or is that per snippet? I don’t see myself putting up many slides with code on them, I’d prefer to talk more about architectures, etc.
