is it basically a defined shape around islands, with shore automatically detected by a trace inwards?
Yes but it is still not great.
i am sorry for the delay.
I do not think we(3dgs comm) have enough quality water shader.
So I would continue to work.
We need noise effects for animated normalmap&heightmap.
i integrated
Projgrid 's noise effect, to 3dgs.
I am currently working on this.
