I’m working on a puzzle game featuring islands: there is a plane with a water shader, and objects colliding with that plane.
Now I’d like to make lakes on the islands, with different (higher) water levels than the ocean’s.
The problem is that if I put a water plane in a “hole”, I can see the ocean below at best, or even worse, the upper water surface just glitches out and disappear.
One option is that I move the lake’s basin higher than the ocean’s see level. This works, but I it doesn’t look so good, because the lake becomes too shallow.
Another option is that I cut holes in the ocean’s plane, but that seems a bit overengineered, isn’t it?
Is there a better solution?
Also having a water plane for every “lake tile” causes some problems:
but I want to have dynamic lakes, so having a 2×2 water plane for a 2×2 group of lake tiles isn’t a walkable path.
