2D tiles that follow an Earth-like curvature ?

Hello everyone

Earlier today, i’ve found this video on the internet : 2D Faux Gravity and round platform generator - demo in unity3d - YouTube
We can see that the player can walk around a circular 2D planet with platform that follow the curvature of the level.

I already have the walking/jumping system. But I can’t find how I can do these type of plateform. If someone have an idea of how to do it, what type of Math or assets I need. It would be great !

Thank you very much for your time. Have a nice day !

Ok so I made more research.

I think I can do that with a LineRenderer. I can generate a certain number of point around a circle. This can generate me a nice textured curve. And then I can use the same process to add a polygonCollider2D around this LineRenderer.

I’m still working on this. But I will post some code here if I managed to do that.
