From the video description:
Several months ago, it was suggested to me by a friend that a fun/challenging exercise would be to recreate an environment from an old game I like using modern techniques. I thought this was a great idea, so I have put together a recreation and personal adaptation of The Temple of Time from The Legend of Zelda.
The footage was captured from Unreal Engine 4. Other software used: Maya, Z-brush, Photoshop
