Map Kit Loader

Loads custom maps for Slip & Skid made with the Slip & Skid Map Kit. On its own it adds nothing: install it together with a map that depends on it (for example MegaStunt).

How maps work

When a map is picked, the game loads one of its own levels as a host. The loader hides the host's road and puts the map's track in its place, keeping everything else the game built:

• camera, lighting, fog and scenery of the host level, with extra scenery placed along the map's track;
• the real start gate (countdown lights, starting grid) and finish gate;
• the no-trap zones around the start and the finish;
• the end-of-race podium;
• tyre marks, gravity and the death plane below the track.

The map's road uses the host level's own asphalt and concrete, so surface cards (ice, sand, mud...) repaint it like a stock level, and the scenery changes with the main surface.

Maps also get their own picture, outline and spinning 3D model in the level select.

For players

Install maps with a mod manager; they pull in this loader automatically. Everyone in a lobby needs the same maps at the same version.

For map makers

A map is a folder with a mapkit.json and an asset bundle, built with the Slip & Skid Map Kit (Unity 2022.3.62f3). Put it in BepInEx/CustomMaps/<Map> or ship it as a Thunderstore package depending on this one.

This loader reads only mapkit.json maps, so it works side by side with other map loaders.

1.2.0

• The game's own road pieces in maps (KitStockPiece): a map can place any stock piece (R###B###: straights, slopes, 20-70 m curves, banked turns, Y-forks, half-pipes, tubes...) by name, from its host level or from any other stock level (loaded once per session behind the loading screen). Nothing of the game ships in the map: the real piece is cloned at load time, with its borders, collisions and surfaces. With it the Map Kit rebuilds every official track exactly.
• Seasons: the season under the car now comes from the road piece's own tag, so it switches exactly where the map says (mid-tunnel) even if a surface card repainted the road; spectators see the season of the car they watch.
• Scenery around long road pieces (a whole bend in one piece, like the stock tracks) is only cleared along the road, not across the inside of the bend; a map that lies where its host's own track was keeps the host's scenery as is.

1.1.0

• Seasons: maps can turn on KitMap.seasonalBiomes; during the race each player's look (sky, fog, lighting, scenery, weather, ambiance) follows the season surface under their car (Dirt, Sand, Mud, Ice, Magma). Local and visual only; off for existing maps, in rush mode and in split screen.
• Paint: map decoration can use the game's own toon materials with a colour (KitRoad.paint / tint), so maps can have coloured props (trees, rocks, snowmen...).
• Level select: maps show their real surfaces like the stock levels – every surface's share (it used to show one surface, and leftover percentages from the level shown before), the colour theme of the map's look, and a 3D preview coloured per surface with the game's own preview materials (and the host's road no longer counted as concrete). A map with seasons shows one band per season in the screen's and the card's background pattern, and its difficulty dots in the seasons' colours.
• Scenery around big maps: a host scenery piece is hidden only where its real shape reaches the track (it used to be its whole bounding box, which hid entire hill ranges), and whatever stood on a hidden piece is hidden with it – no more animals or trees floating in the air.

1.0.2

• Per-road surfaces: each map road piece can use its own game surface (Asphalt, Mud, Ice...), so maps can mix surfaces. Pieces without one keep the host road surface.
• The plugin reports its real version.

1.0.1

• Map roads use the host level's own road surface, so the game applies its biome: correct fog, sky, lighting and scenery (fixes far parts of maps drawing flat green).
• Host scenery is scaled to the map's size and pieces that would stand on the track are hidden.
• The tyre-trail camera covers the whole map.
• Prop pieces (concrete or dark asphalt decoration) that are not road tiles.

1.0.0

• First release: loads Map Kit maps on a stock host level (start/finish gates, no-trap zones, podium, lighting, scenery, surface cards).
• Roadside scenery from the host's environment, switching with the surface biome.
• Level-select picture, outline, 3D model and surface count for each map.
