Set size and resolution
Width km and Depth km describe the physical world; Elevation m sets the physical height scale. Sea level is fixed at 0 m. Resolution controls the number of samples, not the width of the world.
For an axis, spacing in metres is world size in metres divided by sample count minus one. For example, 3 km at 1009 samples is approximately 2.98 m per sample.
The Sample Density Advisor offers targets for high-resolution, game and large-world use. Recommendations are advisory until you choose Apply Recommendation; that action changes resolution and layout settings, not world dimensions or generated terrain.
Higher resolution and globally coupled simulations can cost substantial time and memory. Begin with a small selection and inspect the output diagnostics.
Generate and unload regions
- Select the desired cells in Mesh Terrain Regions and choose Generate Selected. Unselected regions remain unloaded.
- Watch the Terrain Generation window for current work and mesh finalisation. Cancellation is explicit; closing the window does not itself cancel generation.
- Select loaded cells and choose Unload Selected to remove those regions. Generate them again when needed.
Delete Generated Terrain is a separate, confirmation-protected cleanup of all EONFORM-generated terrain and related output. It is not undoable; do not use it as a substitute for unloading one region.
