The last two weeks I build the main map. It’s a 2x2 km section. What I got is not perfect and will need a lot of detail work
Most of the time was occupied by basic research of proper use of Unity features.
The first three attempts in terrain leveling were discarded. It was simply impossible to create a huge plausible terrain by raising and lowering the terrain. It ended always with incredible high peaks and low depressions.
The solution was to outline the wanted contour by setting defined heights. That leads to a contour map what was softened later.
The small mountain near the main river bay was used to test detail work. Here the mountain contains a number of small paths and platforms were created.
It seems there is a need to create some more helper tools especially to build proper paths and avoid dead corners where a chare can be stuck.
Fill Water into the River
The second tricky issues are rivers in a sloping terrain. Using the default water is not possible since it works on flat water only. But the rivers and creeks will pass a number of different steps.
As a solution a function was developed. First the map designer defines the water level with contour lines (blue-red). Out of this contour lines a mesh is created using Blender. This mesh can be applied to water prefabs instead of the standard flat water plane.
