Using a resource pack that changes the model of "overfilled" bundles (using the predicate filled>1.0) no longer works in 21w20a.
{
"parent": "item/generated",
"textures": {
"layer0": "item/bundle"
},
"overrides": [
{ "predicate": { "filled": 0.01 }, "model": "item/apple" },
{ "predicate": { "filled": 1.01 }, "model": "item/diamond" }
]
}
Reproduce:
1) Create a world in 21w19a and give yourself a filled bundle, and an "overfilled" bundle
/give @s bundle{Items:[{id:'minecraft:stone',Count:1b}]}
/give @s bundle{Items:[{id:'minecraft:stone',Count:65b}]}
2) Enable the attached resource pack
3) Note that the items have unique textures
4) Create a world in 21w20a (or upgrade that world), and the filled and overfilled bundles have the same textures.
I cannot reproduce this issue in 1.17 release candidate 1
