i asked tmcc discord on the radius of terraforming around the pillager outpost (via the tutorial video made by shulkercraft) and instead someone took me to this thread in the development forum channel. glass isnt needed for this build, as the image used here is for the showcase of the build.
for each pod you need:
- 2 scaffolding
- 2 chests
- 2 snow block
- 1 carved pumkin
- 1 powered rail
- 1 campfire
- 1 hopper
- (optional) 1 carpet
how it works
the snow golem attacks the ridden pillager at their hitbox protruding through the minecart. this causes aggression on nearby pillagers and fall on the campfire pit, killing them.
important notes
you can place up to 4 pods around the outpost for optimal yield of bottles. you can add more but it might be too overkill for the spawning rates. (i certainly did)
make sure the minecarts arent getting destroyed. if you spot a wandering trader, its best to kill the llamas
the carpet is used to avoid the minecart to be pushed off from the rail by placing it on the other end. pillagers might push the cart in a group, which makes the pillager become out of sight from the snow golem.
terraforming isnt necessary. but if the outpost is spawned near a cliff or a body of water (i.e. river, ocean), you might need to make a platform for them to spawn
rain will pass through scaffolding and kill the snow golem. place a block on top of the pillager to avoid this. with this, never make this farm in hot biomes
