Poster Grid Snap

Poster Grid Snap

Clean horizontal and vertical alignment for wall posters.

Poster Grid Snap enables Retro Rewind's existing placement grid for wall-mounted poster frames and adds the missing vertical axis.

Regular and small frames now click into clean rows and columns while the original wall orientation, collision validation, ghost visuals, placement sounds, final transforms, and saves remain intact.

Main Features

• []Two-axis alignment - Snap wall posters horizontally and vertically.

  []Vanilla grid size - Uses the game's current Grid Size Snap value.

  []Regular and small frames - Supports the wall-mounted PosterFrame classes.

  []Floor displays preserved - Standing and two-sided displays retain vanilla free placement by default.

  []Collision-safe - The final snapped position is applied before vanilla collision validation.

  []Save-safe - Final placement transforms and save handling remain vanilla.

  []Lightweight release - UE4SS module only; no PAK or cooked asset replacement.

  Requirements

  • []Retro Rewind - Video Store Simulator

    []UE4SS

    []Tested with UE4SS 3. 0. 1 Beta #0

  Installation

  • []Install UE4SS in the game's RetroRewind/Binaries/Win64 directory.

    []Download the latest Poster Grid Snap archive from the Files tab.

    []Extract the archive.

    []Place the included PosterGridSnap folder inside RetroRewind/Binaries/Win64/ue4ss/Mods.

    []Restart the game completely.

    The final files should be located at:

    RetroRewind/Binaries/Win64/ue4ss/Mods/PosterGridSnap/enabled.txt

    RetroRewind/Binaries/Win64/ue4ss/Mods/PosterGridSnap/Scripts/config.lua

    How It Works

    Poster frames normally opt out of Retro Rewind's existing placement grid. The mod enables that vanilla policy only for regular and small wall-mounted frames.

    The game already snaps the horizontal world axes. Poster Grid Snap rounds the vertical Z component by the same grid size inside GhostMesh_C:Snap Grid. This happens before the ghost moves and before collision validation, so the visible position and placement result remain consistent.

    The mod changes only the snap-policy output and temporary vertical grid location. It does not move already placed posters or replace the final save transform.

    Configuration

    PosterGridSnap/Scripts/config.lua includes:

    • []Enabled - Enable or disable all behavior.

      []IncludeStandingPosters - Opt standing displays into the vanilla grid.

      []IncludeTwoSidedPosters - Opt two-sided displays into the vanilla grid.

      []DebugLogging - Enable one-time placement diagnostics.

      Standing and two-sided options are disabled by default because those displays are primarily floor-placed.

      Compatibility

      • []Tested with Steam App ID 3552140.

        []Tested with Steam build ID 23896268.

        []Created for Unreal Engine 5. 4. 4.

        []Compatible with existing save files and already placed posters.

        []Does not replace cooked assets, Player Character, GhostMesh, or the store map.

      • Uses the game's current grid size.

        PlacementBypassToggle

        Poster Grid Snap is designed to coexist with PlacementBypassToggle. Poster Grid Snap changes the grid location, while PlacementBypassToggle changes placement validity later in the workflow.

        When the bypass is enabled, posters still snap to the grid but may be accepted in overlapping positions as expected.
