First-off, I got to emphasize that considering Unreal as a replacement for Carrara is like considering a spacship cruising at warp speed as a replacement to a 2004 Toyota Corolla clunker. They're just not in the same league, really.

Second-off, I won't give any link to the Unreal web site, because if at your age you don't know what Unreal is, then your case is desperate.

I'll begin by saying that Unreal is not just a game engine with space-age performances, it is also used worldwide by architects, advertising firms, engineering firms, TV stations, movie producers, etc, etc.

Before going into a lengthy review of Unreal, let me direct you to these 3 teasers to give you a taste of things to come. And don't forget, these teasers are REAL-TIME renders, not renders that took 6 months with 500 computers.

See this link, and this link, and this link.

More on UE4 later, if I have time.
