Seems to be a lot of things on sale (50% off) at the asset store right now....not sure if anything is applicable, compatible, useful or even supported at the version we are required to use...but here's a link...

This one caught my eye...anyone tried this approach before to generate a terrain?

I think the sale runs for a couple of weeks.
Thanks,
