Minecraft PassthroughIV
Draws a real Minecraft Java session into GTA IV's Liberty City.
What it does
An ASI plugin and Fabric mod pair that runs Minecraft Java next to GTA IV and renders it from GTA's camera. Blocks are solid for GTA peds and cars, TNT and creepers explode in both games, there is a shared health bar, and Steve's crimes earn wanted stars. The uploader's own page recommends a different GTA IV project as better; that video links to mrborghini, whose LibertyCraft is already catalogued.
How it works
Passthrough: an ASI plugin in GTA IV plus a Fabric mod over WebSocket. GTA's camera drives Minecraft's, GTA ground becomes Minecraft collision, and depth-tested compositing is used. Ported from rehan-remade/universal-modder's GTA V example.
Requirements & limitations
GTA IV CE 1.2.0.59, Ultimate ASI Loader, Minecraft Java 26.3 + Fabric Loader 0.19.5+ + Fabric API, Java 25, separate MC install
