This resource pack was created to simplify supporting older versions of Minecraft!

Template Model Backporting

All models containing cube or template elements are adapted for compatibility with previous versions, except for cases where their parent element has builtin/entity properties.

Item Redirections

For items whose identifiers have undergone changes, an automatic redirection system is implemented according to the following scheme.

{
  "parent": "<insert new location>"
}

old_location.json

This approach allows transferring all characteristics from the updated model to the outdated version, including textures and other parameters.
