Texture Slots

Every Texture Slot gets one function per texture in it:

<blueprint_id>/texture_slots/<slot>/<texture>

Running one switches every face in that slot, on every bone of the rig, to that texture. Other slots aren’t affected.

These functions must be run as the root entity of the rig, and require Minecraft 1.21.4 or newer.

# Close the eyes of every my_rig instance
execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/texture_slots/eyes/closed

<slot> and <texture> are the exported names of the slot and texture. See Names for how they’re made.

They return success 1, so you can use them in execute if function:

execute as @e[tag=my_pack.my_rig.root] if function my_pack:my_rig/texture_slots/eyes/closed run say Blink!
