Perlin Noise Islands

Alright, no matter how far I look, I cannot find a single helpful tutorial that is up to date on how to make a procedural island generator using noise. I keep getting this garbage sad excuse of an island which is literally just random noise but fancy. As you can see here:

My current method is creating a 3D noise that essentially just makes hills, then a script converts all of the parts to be on the same Y-Level to make it 2d.

My goal is to get the island generator to resemble this:

The way I’ve seen this accomplished using gradients but I have seen no information on this for Roblox.

I actually found a gif that perfectly illustrates what I’m trying to make possible on Roblox (The first few frames)

How could I effectively create an island Perlin noise generator? All I’m getting right now are hills.

Google may save the day

This article goes into detail about generating 3d terrain using perlin noise. Specifically, it has a portion dedicated to island generation.

I got pretty confused near the middle but I did manage to get something that im satisfied with. It now looks like a bunch of islands that are clumped which is close to perfect for my gameplay. Thank you both so much!!
