Wrong water level on Islands - Not Actually Fixed

This is still an issue: Island of Ushant used.. and the entire around around the island (which on the map is the darker ocean colour) is set to be incorrect terrain height.

also the exact same issue for islands not included in the map, but included in the outer terrain area..

the edge of the terrain cannot be edited using deformer; thus it cannot be fixed temporarily using that tool!

Hi,
The result heavily depends on OpenStreetMap data, it might be an other edge case that the algorithm does not supports.
Can you send me the coordinates used ? It will help find out what went wrong

Exact same issue with another map, different location: 52.8501528455348, 158.46460989667648

you can modify the heighmap with Deformer and import modification via Export to gamerealistic

**You cant modify the edges of a terrain though. Which is a big part of the issue. **

You can modify the edge in L3DT

Hi, In fact this is caused by two issues:

1. Ocean depth data precision is low (272m grid precision on this location), and the algorithm used to compensate it does not works well for islands with this shape. It needs to be reworked (ocean depth should be proportional to coastline distance).

2. Area is not detected as an island due to really small islands at the edge. This allows "synthetic" terrain outside the area that should not be enabled on this specific case. Detection algorithm needs also rework.

Workarounds:

• For the first point, as outlined by @Valou130901 you can use Deformer + Export to GameRealisticMap to make to fix ocean depth and add missing islands
• For the second point, you can edit mapinfos.hpp and change enableTerrainSynth to 0

Second point is fixed by #266
