Thanks for your appreciation and the keen interest you had in this video.
Most of the assets are meshes created from scanned images from various ancient Temples in India using Reality Capture.
Frankly, at first I was very skeptical if I could get the right render of what I had in mind. But as I brought the assets into UE and started playing with light, everything just fell in place.
I was keen on getting a mysterious look and feel and UE was just too good.
I have to admit that I was very much fascinated by the work of @ScansFactory especially their Ancient Temple ruins.
At the end of the day, it is how easy to convert your thoughts to renders with UE.
Cheers.
