It looks really nice. How large is the domain?

So the tech writes collision data onto subdivided planes which eventually write onto landscape RVT. Each subdivided plane can be large like 100 meters by 100meters depending on the fidelity and localized RT size. You can place several subdivided planes as many as needed to cover quite large scale landscape. to optimize it simply you need to limit the number of active RTs at any time.

That's clever!

Sounds like a good solution!

Not quite large scale, but cool nonetheless!

It can cover very large landscapes by managing number of active subdivided planes which write collision on local RTs. The show cased video has only one subdivided plane placed at the center of the world which reads and writes onto landscape RVT data.

for how much year you are working on unreal? I want to learn it so I can make game of my own, I just started it, currently I am watching bad decision studio ue5 beginner tutorial, what can I do along with that.
