Some caves are made by me, some caves are made by Mark, some caves are made by Gustavs.

Oh, the line in the ground.

That's because of the cave's line.

It's essentially the line that it follows.

It's just a mesh, but if I can show you, for example.

This essentially determines how the mesh flows.

and the numbers indicate which spline point we're at.

So this is the first spline point where there's also a zero, that's the mouth of the cave, and then there's the spline point one.

And that way we can make more of these kind of almost tunnel-like caves instead of having to mess around with a lot of separate meshes.

So this is a lot more optimized and a lot easier to work with as well.
