MyCelium WikiFAQ
Do players need the mod to use the poses?
No. With the mod on the server, every player can switch poses with sneak + right-click, use shears on the base plate and get arms on new stands, even with a vanilla client. Turning with R, the pose preview and the new texture need the mod on the client too.
Will it change my existing armor stands?
No. Stands that already exist keep their arms (or lack of them), pose and base plate. Only new stands get arms, and a stand only changes when you click it or the redstone signal next to it changes.
R does nothing
Look straight at the stand (the crosshair has to be on it) and hold the key. The server needs the mod as well, and allowTurning must be on. If another mod uses R, rebind "Turn armor stand (hold)" under Options, Controls, Gameplay.
Sneak + right-click took my item instead
Poses only switch with an empty hand. With an item in your hand, the click works like vanilla and puts the item on the stand.
Can I still make custom poses?
Yes. Commands, data packs and other pose mods work as before. Sneak + right-click on a custom pose goes back to the first pose of the list.
Why does the redstone pose not change when I place a stand next to a powered block?
A stand only reacts when the signal changes, so builds next to redstone are never reset on their own. Flip the lever or button once and the stand follows.
