Different models/textures for different damage values, stack sizes and item states
Works on compass, clock and everything that can have a durability bar, bows have different property states for pulling, how far it's been pulled & fishing rods differentiate between cast and not cast
Models can be put together based on BlockState attributes - Example: fences - As a result, the vanilla set of block models was reduced by almost 300 models
Better rotation & translation handling and consistent left hand support
You can set different models for use in the off-hand and head slot
Blockmodel JSON is now strict, comments and quoteless identifiers are not allowed.
"display" tag defaults have changed, see assets/minecraft/models/block/block.json for offsets
Parent and elements tags can coexist now
Removed the option to disable alternate block models
블록 상태
Fire block states flip and alt were removed, and the integer state upper was reimplemented as the byte state up, cutting the number of states representing fire from 3072 to 512.
