how to edit something for multiple models at once?

[wheat geode]

im trying to change the display location for hundreds of models but opening and editing them one by one is way too time consuming. how can i edit the same setting for all of them at once or automate the process?

Assuming you are talking about the display settings, giving all of them a parent model and defining the display settings only in that parent model would be what you want.

@red galethanks for replying. would you be able to give a brief guide on how to do this? i barely know how to use blockbench and will try this later with a lot of googling regardless

this is not specific to Blockbench, but to how models work in general

if you want a lot of models to share the same information a parent model is preferred, since you only need to edit the parent model that way, not every single model file

Explanation: A parent is an optional reference to another model file. If it is specified your model will inherit information from the parent file (textures, elements, display settings, etc.) if that information isn't already specified in your own model.

Changing/setting a parent: Go to File > Project... and put a model reference into the parent field. Model references always start inside the "models" folder (so example/custom will look for assest/minecraft/models/example/custom.json)

Common mistakes:
-Do not force yourself to specify a parent if you don't need it. A model can work just fine without one. A reference to a non-existent parent file will cause your model to be an error block!
-Do not use item/generated and item/handheld in combination with a custom made model. (The game would try to generate a model based on your texture with those parents, and then gets confused with your custom cubes/elements you added to the model).
_ Feel free to use them to generate models from textures though (just like in the vanilla files)._
