There are two terrain layers in the landscape and Water layer created as a Water body.
I want to merge two terrain layers into one.
How can I merge them?
It’s not a perfect solution, but I found one.
I exported each layer as a heightmap and combined the two layers using the overlay blend mode in Photoshop.
Afterwards, there was a problem with the height of the entire layer changing, but I was able to merge the two layers into one by covering them with a translucent black rectangle in overlay blend mode and adjusting the opacity.
