Learn more about RPT →Why RPF & RPT?
Minecraft's resource pack system loads only the top-priority pack's model for each item. This makes it difficult to combine multiple resource packs that modify different items.
RPF: Resource Packs Fusion
Solves this by introducing a delegation system - packs can selectively override models and delegate the rest to lower-priority packs.
