This mod draws an extra outline around the building's actual footprint on the ground, on top of the normal ghost. The outline color follows whether placement is valid (green = buildable, red = blocked). Updates 1.1: improve performance

Building Placement Outline - Ground Footprint Preview for RimWorld

See exactly which ground tiles a building will occupy before placing it. The mod adds an outline around the building’s actual footprint, alongside the normal placement ghost.

The outline changes color to show whether the selected position is valid:

  • Green: the building can be placed.
  • Red: placement is blocked.

This makes the occupied area easier to distinguish from the building’s visual preview when planning construction.

Version 1.1 improves performance.
