Additions (1.21.5 only):

• Spawn eggs interaction

• Adding Grumm, Dinnerbone and jeb_ to spawn eggs will now flip them.
• Setting the variant block_state to "warm" or "cold" will reflect its change on cow, pig and chicken spawn eggs.
• Setting the Color (Uppercase C) block_state to the color strings or a number between 0-15 will also reflect on the sheep spawn egg

• Leaves

If you want the new stuff in 1.21.4 you can change the pack.mcmeta to lower the bounds of the addition to the main version.

This is a big one

Additions

• Campfires
• Creaking heart

• Slabs states
• Stairs states
• Waterlogging for stairs, walls, signs, ladders, chests, fences, slabs, campfires, big dripleaves and some others probably
• Powered overlay for hoppers, note blocks, doors, trapdoors, fence gates, bells, observers, dispensers, droppers

• [POLYTONE ONLY] Custom creative tab with certain blockstates and items. Currently only used for lit redstone lamp my beloved and the custom armor stands

Changes

• fixed brick and tile walls
• changed tnt overlay so that its fullbright in the inventory

Added the following:

• Observer (it works without any other resource packs, but preferably add one that changes the observer more when active to see changes in the gui)
• Mushroom blocks
• Bell
• All signs
• Lantern and soul lantern

Also added snowy grass, mycelium and podzol blocks. All of the above have their blockstates reflected (except signs since those are separate blocks)

Added:

• All Buttons and pressure plates

• Sculk catalyst
• Big dripleaf and blockstate for the small dripleaf
• Lectern
• Lightning rod

Also changed the sculk sensor to also use its blockstates

With that, most of the redstone tab is now done

• fixed chests breaking due to christ

late because i didnt have internet

• Added doors

Yes, all 17 of them, with their open, half, and hinge states (If i had a nickel for every time I've wrote a python script for a minecraft resource pack I'd have 2 nickels)

First update so far. Got into a nice workflow now, so things are going fast
