Signage Piece Mod

The Signage Piece Mod (SPM) is a mod by the NAM team, unreleased but currently in progress, which consists of a series of 1x1 Puzzle Pieces for the various networks that have signs in Prop Families attached via Type21 Exemplar. It is designed to solve the issue that the Lot-based solutions for signage implementation resulted in, such as extra space consumption and CTDs from TE Lot-based sets, while allowing the user to control signage placement, unlike a standard T21-based mod.
