This is the first Vanilla release of the pack. It doesn't have the particles of the regular counterpart. This will be updated eventually for parity

Changelog

• Fixed lightning rod missing its view angles

Particle update

The texture pack will now be split into Item interactions and Item interactions Vanilla

The main pack will have compatibility with the Item interactions mod, while Vanilla will be strictly vanilla.

Added particles:

• Leaves
• Firefly bushes
• Buckets
• Torches, repeaters and comparators
• Sculk sensors
• Campfires
• Note blocks and jukeboxes
• Pots
• Dispensers, droppers and crafters
• Open Eyeblossom
• Enchanting table
• Brewing stand
• End rod
• Tnt and tnt minecart
• End crystal
• Firework rockets
• Ender eyes
• Soul sand and soil

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.
