Following the method outlined by diesieben07 here, I'm attempting to override a texture for a custom potion. I (think?) I have the full ModelBakeEvent implemented, but I'm not sure if it's running, as I get no response similar to here. The new model is being added in the ModelRegistryEvent though. Below are my event classes and item model. Thanks!

@Mod.EventBusSubscriber(modid = Main.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD)
public class ModSubscribeModEvents {

    @SubscribeEvent
    public static void onModelRegistry(ModelRegistryEvent event) {
        System.out.println("Added model");
        ModelLoader.addSpecialModel(new ResourceLocation(Main.MOD_ID, "item/new_potion_model"));
    }
}

        ModelResourceLocation newLocation = new ModelResourceLocation("mod_id:new_potion_model#inventory");
        IBakedModel newModel = event.getModelRegistry().get(newLocation);
        ItemOverrideList newList0 = newModel.getOverrides();

                if (stack.getItem() instanceof PotionItem) {

    }
}

Thanks. Sorry for the stupid mistake. The event is firing, but I'm not sure what to do with getOverrides(), unlike resolve() that has constructor parameters to check with. Trying to return or use newList0.getOverrides() here is null. The resource location should be correct.

You should seriously name your variables better.

Yeah I was confused and labeled both as newList. I'm returning:

ImmutableList<ItemOverride> oldList = oldModel.getOverrides().getOverrides();

in newList1.getOverride now.

I'm not sure what using oldList in newList1.resolve would do though, since the checks for the itemstack already exist, and new model is returned here. Unless it's for another form of check (what vanilla does). I also can't debug resolve as console outputs there don't work (or something's preventing it).

I appreciate your help. I've read the forge docs and tried finding similar examples, but this event hack is something else.

No. Refer to oldModel.getOverrides.

Understood, the return for newList.resolve() should be oldModel.getOverrides().resolve(params). It didn't dawn on me that 'proceed as previously' in step 4 referred to the oldModel here as well instead of the method's super, but it makes sense since you specified it should in step 3.

In newList.getOverrides, oldImmutableList already derives from oldModel.getOverrides, but I'll inline the variable if it makes a difference (oldModel.getOverrides().getOverrides())

Meant to follow up on this, but I discovered that brewing recipes can also be registered to BrewingRecipeRegistry vs trying to swap out textures for potions. I was only familiar with the reflection method, but it's neat that there's two ways. Doesn't address the original problem, but code below for future visitors:

Registry:

private static void commonSetup(FMLCommonSetupEvent event) {
    event.enqueueWork(() -> {
		ModEffects.addBrews1();
    });
	ModEffects.addBrews2();
}

Methods:

public class ModEffects extends Effects {

    public static final DeferredRegister<Effect> EFFECTS = DeferredRegister.create(ForgeRegistries.POTIONS, Main.MOD_ID);
    public static final DeferredRegister<Potion> POTIONS = DeferredRegister.create(ForgeRegistries.POTION_TYPES, Main.MOD_ID);

    public static RegistryObject<Effect> MY_EFFECT    = EFFECTS.register("my_effect", MyEffect::new);
    public static final RegistryObject<Potion> MY_POTION     = POTIONS.register("my_potion", () -> new Potion(new EffectInstance(MY_EFFECT.get(), 1)));
      
    // Method 1
      
    public static void addBrews1() {
      BrewingRecipeRegistry.addRecipe(Ingredient.of(ModItems.INPUT_ITEM), Ingredient.of(ModItems.INGREDIENT_ITEM), new ItemStack(ModItems.OUTPUT_ITEM));
    } 
      
    // Method 2 (vanilla-style, adds splash, lingering, and arrow variants)  
      
    private static Method brewing_mixes;

    private static void addMix(Potion start, Item ingredient, Potion result) {
        if (brewing_mixes == null) {
            brewing_mixes = ObfuscationReflectionHelper.findMethod(PotionBrewing.class, "addMix", Potion.class, Item.class, Potion.class);
            brewing_mixes.setAccessible(true);
        }
        try {
            brewing_mixes.invoke(null, start, ingredient, result);
        } catch(IllegalAccessException | IllegalArgumentException | InvocationTargetException e) {
            e.printStackTrace();
        }
    }

    public static void addBrews2() {
        addMix(Potions.AWKWARD, ModItems.INGREDIENT_ITEM, MY_POTION.get());
    }
}
