Need Landscape for my game

I am using a computer that is not compatible with most forms of landscape editors. would anyone be willing to donate to me a landscape for a large island? Please help, I will find a way to acknowledge all the people who help me make my game. Perhaps I can list their names in a credits scene in the game?

Why don’t use the terrain heighmap to make the island? You just need to change the jpg file that give the shape to the island and a box for the water surrounding the island

where is the terrain heightmap?

There’s no terrain plugin for PlayCanvas (yet!). But in the meantime, you can generate a terrain mesh from a heightmap image as demonstrated in this tutorial project:
