Raising waterline raises elevation.

[lukeprtr 10]

I raised my waterline in L3DT because the entire ocean was like 1/4 meter deep. So I went in L3DT and raised it the waterline and it raises the terrain under it aswell. How can I fix this?

I was told you just have to change the minimum and maximum values. For instance, I have mine currently set to min. -15m and max. 150m. If the waterline is 1m above the level I wanted, the land is too low, so I want to raise everything up 1m. I would then change those values to -14m and 151m. At least that's what I understood, maybe I have that wrong. I haven't gotten this far yet though, I'll have to confirm this later.

Ok thanks I will test to see if it works, hopefully it does.

yep! it works thanks!

this is not working for me. my waterline raises but terrain will not follow acordingly

think if you dont have enough room to go on. eg: if minimum height is at -1, this would not work. If you raise the minimum to lets say +15 and the max, the seabed will follow and water level will be at 0. so then you end up with no water at all

Yes - this trick is really only useful when you have a decent depth of "ocean" to play with... if you have -100m minimum then hiking the whole terrain up by 10m just means max sea depth goes to -90m - not a big deal.

However - if you've got no actual sea depth at all - hiking the land up in the air is just pushing what little seabed you have upwards too...

You tend to run into this sort of issue mostly with "Real World" heightmaps, since they're mostly derived from orbital optical/radar sensors which basically "stop" when they hit the sea surface.

With these sort of maps you really need to - identify on the heightmap exactly where the coastline should actually be - then "carve out" the sea with some sort of heightmap editing tool such as L3DT or Leveller....

When you raise your max 1 place you need to lower your minimum down 1.

So my terrain

Min: -36

Max: 400

With edits

Min: -72

Max: 436

Hope you understand -Luke

I think you might be a little confused here...

Let's look at your numbers....

So my terrain

Min: -36

Max: 400

So.. the range, or spread of height values on your terrain is 436 meters - from the lowest point to the highest point...

With edits

Min: -72

Max: 436

Now the range or spread of height values is 508 meters.

In effect, you've stretched the heightmap so the lows are lower and the highs are higher...

You need to preserve the range, otherwise you're distorting the landscape...

When you raise your max 1 place you need to lower your minimum down 1.

It should actually be "When you raise your max 1 place you need to raise your minimum UP 1 as well".

Basically - the water stays in the same place always - at Zero meters. What you have to do is shift the whole landscape up or down relative to that, whilst at the same time preserving the range of the heightmap...

Hope that makes sense....
