Description

Wouldn't you like to add cool rendering to GregTech CEu Modern? But that requires Java? Don't worry! This mod solves that.

We only support 1.20.1 Forge because that's where GTCEu is.

Example:

in startup_scripts:

GTRenderJSEvents.registerModelsForRender(event => {
    event.register("kubejs:obj/space");
    event.register("kubejs:obj/star");
    event.register("kubejs:obj/foo");
    event.register("kubejs:obj/bar");
    event.register("kubejs:obj/baz");
});

These obj files should be placed in /assets/kubejs/models.

in startup_scripts (gregtech multiblockmachine registry)

// before
.workableCasingModel(
            "gtceu:block/casings/solid/machine_casing_stable_titanium",
            "gtceu:block/multiblock/implosion_compressor"
        );
// You will use this instead of that.
// after
.model(
            GTMachineModels.createWorkableCasingMachineModel(
                "gtceu:block/casings/solid/machine_casing_stable_titanium",
                 "gtceu:block/multiblock/implosion_compressor"
            )["andThen(java.util.function.Consumer)"](b =>
                b.addDynamicRenderer(() => KubeJSDynamicRender.of("kubejs:example"))
            )
        );

in client_scripts

const OverlayTexture = Java.loadClass("net.minecraft.client.renderer.texture.OverlayTexture");
const RenderType = Java.loadClass("net.minecraft.client.renderer.RenderType");
const LightTexture = Java.loadClass("net.minecraft.client.renderer.LightTexture");
