I created a SciFi looking Underground tunnel I. blender 2.83.
Then I thought why not just make an animated walkthrough instead of rendering just a single frame!! Here is the result.
.
It took 2 hours to model the tunnel
3 hours to animate the camera, focus, etc
8 hours to render (used Evee Render Engine)
3 hours to Edit and add sound effects
.
A total of 16 hours. But I think it's worth the time.
I know it's just a 20 second video. But that's a lot considering I'm doing this all on my 6 year old laptop.
