Hi. I watched this.
Cesium Deep Dive, Part 5: Real Time Fun with Cesium and Unreal Engine
It was impressive. Can I have a tutorial about this session?
Hi @seongholee, welcome back to the community!
Indeed, Stephen put together some really cool demos for that talk. 
This would be a great addition to our documentation! I opened a GitHub issue for this here.
Stephen shared his material graphs in slides, at least, so it’s possible to reconstruct them. But let us know if you have any specific questions we can help with!
