    This is the AMS2/PC2 version of my G&J Kartway 2024 model. To my knowledge, this is the world's first original track model for any Madness Engine game. All other track mods for AMS2 are ports from PC2 and earlier Madness Engine titles; this proof-of-concept is to show that arbitrary and original track models can be made for AMS2 and PC2. This model is much more of a proof-of-concept than a finished product. Despite that, it is perfectly playable, even in multiplayer.

    You can download the track model here. This page is currently the only place of distribution of this model; I'll post it on Overtake.gg if and when they add an "AMS2 Tracks" section.

    The file is correctly packaged for auto-installation with AMS2 Content Manager. If you need to install it manually, "bootfiles" need to be properly extracted (to allow the track to load unpacked) and "tracklist.lst" needs to have the track's filepath added. The track can also be installed into Project CARS 2, but it must be installed manually as just described.

    The following features have been implemented and are working:
    • Replay cameras
    • Computer opponents (they're a little slow sometimes)
    • LiveTrack (see below)
    • Lap timing
    • Pit stops
    Certain features are not working properly yet:
    • LiveTrack visual overlays: due to a bug in the MTX material definition file format handling, the DEFINE parameters aren't fully stored properly, leading to some of them not taking effect, specifically the LIVETRACKRENDERING flags, which enable the rubber, dirt, wetness, and puddle effects. Despite this, those attributes are still physically present: the track will rubber up, become wet, and develop puddles; the track state presets also work properly.
    • Track cut/illegal overtake detection: the GCL file, which stores track boundary lines and other related info, is not correctly loaded when the track is running "unpacked" (not packaged into a BFF).
    • Painted lines: I had them working earlier (as shown in the below screenshots), but I was experimenting around with different shader options which broke the painted line materials, and I didn't have time to undo my changes before this release. I'll try to fix it for a later release.
    • Collidable objects (cones, etc.): I haven't yet done enough research on the dynamic physics object system to make it functional for this track.
    • LiveGrass: I haven't researched the LiveGrass format yet, so the track does not feature 3D grass blades.
    • Weird-looking trees: The tree shaders are odd looking due to my inexperience with the options provided with every shader present in AMS2. I'll try to improve their look for a future update.
    If you also play Assetto Corsa, a version of this model for it is available here.
    If you also play Kart Racing Pro, a version of this model for it is available here.

    Originally opened in 1958 as a dirt track, G&J Kartway is one of the US's oldest operational karting tracks and was the founding place of the WKA. Its resident club, OVKA, has been holding races at the track since 1964. The track was recently repaved during the off season between 2023 and 2024. It features two main layouts, with the long layout having an optional chicane, and the final corner complex can be configured in one of three ways for a total of 9 layouts. The track is also occasionally run in reverse.

    Congratulations on being the first person to reach a very significant milestone in AMS2 modding!

    I tested the track in Single Race with the 4-stroke karts, and I'm amazed how many features you've gotten to work in this initial release. Well-deserved praise!
