What?

What are the files "Layer_1"?

These are huge. Is this the shader settings saved?

The layer_ files are heightfields. For the terrain, for the project and for the flowmap.
The project saving does not work at time, because the new features are not supported.
Iso lines, shader, .... are saved at time only as terrainpreset.
The shader is not stored at moment, but produced on the fly.

So all i need to save is the .GTS File then and can i get rid if the rest of the preset files?

[cajomi]

yes, store the terrain preset and all is stored, including render settings and shader settings, isolines, filters.
But only the settings are stored. So after loading a terrainsetting you have to push "generate". Then the exact same terrain (if keep seed was checked) is generated and displayed.
