Fill missing map tiles: Fill missing regions:

Enabling "Fill missing regions" significantly increases render time because each region inside an existing map tile has to be checked individually against the upstream server.

Saved colours

Colours you save here appear as preset swatches in every colour picker on this page. They are stored on your account, so they follow you across browsers and devices.

Add a colour
Draw region rectangles Draw region names Draw region grid coordinates Region label font

Region names and grid coordinates are only drawn when each region is rendered large enough for the text to fit and the render covers a limited number of regions (roughly a 32×32 area) — at smaller sizes or larger areas the names will not fit and resolving every name would be too slow, so they are skipped. The rectangle outline is always drawn when enabled.

Themes

A theme bundles the presentation settings on this page — the fill colours and toggles, the region-overlay options and label font, the GLW style overrides and font, and your route colour. Save the current look to your personal library or to a group, then apply it later. Group themes can be applied by every member, but only created or changed by group owners. Theme names must be unique within each library. Rename and delete saved themes from the Library page.

## Preview

Tiles are aligned to the SL map CDN's tile grid, so the preview can include regions outside the requested rectangle — those extra regions will not appear in the final render. Each free slot is drawn as a green box (red if its content does not fit); use the buttons in a slot to place a text label, logo or the GLW legend, the button on a shared edge to combine two slots, and the split button to break a combined slot apart.

Show free slots

Drag a rectangle on the map to zoom the selection into that part of the current area.
