It segments the horizon in several tiles (usually 4 or 8), therefore allowing very high resolution horizons also on limited hardware, and closes the ground with a separate bottom piece. (You may want to configure a map with pointers to surrounding mountains or a compass rose instead!) You can use panoramas created in equirectangular or cylindrical coordinates, for the latter case set [landscape]tan_mode=true. Until V0.10.5 there was an undetected bug involving vertical positioning. For historical reasons (many landscapes were already configured and published), it was decided to keep this bug as feature, but a fix for new landscapes is available: [landscape]calibrated=true. As of 0.10.6, the fix is only valid for equirectangular panoramas. As of V0.13, [landscape]calibrated=true and [landscape]tan_mode=true go together for cylindrical panoramas. It is more involved to configure, but may still be preferred if you require the resolution, e.g. for alignment studies for archaeoastronomy. In this case, don't forget to set calibrated=true in landscape.ini. Since V0.13.1, also this landscape has a self-luminous (light pollution) option: Configure light<n> entries with textures overlaid the tex<n> textures. Only textures with light are necessary! Can be easily made using layers with e.g. Photoshop or Gimp.

However, texture image sizes must be computed in subclasses. The value returned is a sum of RAM and texture memory requirements.
