How to make it so that water doesn't cut into terrain?

[MRPENNYMISER (Scrat)]

I’m trying to add water in my terrain map using the “add” function. But when I put it in, it cuts though the terrain.

When filling map with water using Terrain:FillBlock() water cuts through all the terrain

What do you want to achieve? Keep it simple and clear! I am working on a procedural world generation script, but I have encountered a problem with water What is the issue? Include screenshots / videos if possible! I was working on adding the water and I noticed that the water cuts completely through all the terrain. You can swim under islands because of this. I am using Terrain:FillBlock which has no ignore water feature or anything. Is there any way around this? I create the water fir…

I have looked on this post, but I am not generating a map. I am simply just putting water inside of a pre-generated map.

So I don’t really think there is a way to prevent water from cutting into the terrain. Your best bet would be to simply add in the water and then clean up the aftermath. That would be my suggestion.

just enable merge empty when using the fill tool (nvm I don’t know how to do it with the add function, but fill region sounds easier to me)

I would try using the model terrain replace plugin, it might make it easier to get better details, if not maybe making the water above it then using the move terrain thing to lower the water into the terrain?

Not going to be the most reliable way since “air gaps” could form. You’d have to be extremely precise with moving the terrain to fill every gap.
