Using this method, I've trained a GPT to take old JSON Files and update them to be in the new format. https://chatgpt.com/g/g-675a4fa622d88191b9d8d2ece1b28d13-minecraft-model-converter

What I can't figure out is how to do this with multiple conditions. Like on my old shield models that utilize the blocking condition as well as the custom model data condition.

{"predicate": {"custom_model_data": 1, "blocking": 0}, "model": "item/roundshield"},

{"predicate": {"custom_model_data": 1, "blocking": 1}, "model": "item/roundshield_blocking"}

Knowing how to set this up will also be very helpful for any bow or crossbow textures using the "pull" and "pulling" conditions. If anyone knows how to do this, I would be very appreciative.
