[1.19.2] Custom shader not rendering on BlockItem

SnakerBone · March 3, 2023

Hi, so I recently made a shader with OpenGL and I'm able to get it to render on the block in the world but I'm having trouble trying to get the actual BlockItem to render. I'm also using GeckoLib & CodeChickenLib, heres what it looks like in game:

Here's my code:

I'm also not missing any block/item JSON's so I'm kind of confused. I have been able to get this working in 1.16 but I cant seem to get it working in 1.19.2

Any help appreciated. Thanks 🙂

You need to add a BEWLR to the item by extending BlockItem, overriding `Item#initializeClient`, have `#getCustomRenderer` return your BEWLR extension, then render the itemstack using your BER there.

Hi, thanks for your reply. I have done this however I am still having the same problem. Here's my new code:

    public SwirlBlockItem(Block block, Properties properties) {

        super(block, properties);

    }

    /**
     * This has no animations to play so we will continue...
     **/
    private <E extends IAnimatable> PlayState predicate(AnimationEvent<E> entity) {

        return PlayState.CONTINUE;

    }

    @Override

        super.initializeClient(consumer);

        consumer.accept(new IClientItemExtensions() {

            private final BlockEntityWithoutLevelRenderer bewlr = new SwirlBlockItemRenderer();

            @Override
            public BlockEntityWithoutLevelRenderer getCustomRenderer() {

                return bewlr;

            }

        });

    };

    @Override
    public void registerControllers(AnimationData data) {

        data.addAnimationController(new AnimationController<>(this, "controller", 0, this::predicate));

    }

    @Override
    public AnimationFactory getFactory() {

        return FACTORY;

    }
}

I'm think I might be missing something. Please let me know if that's the case

Figured it out. I had to put "parent": "builtin/entity" in the block models json. My bad XD
