I just checked out the mod, the description seems to indicate that it "visualizes" village marker data sent from the server. Wouldn't that mean that if the server doesn't supply it, I'm out of luck?
Or did I just misunderstand? It seems a little strange that something purely based on object positions would need to depend on server data.
You're right - IF the [online] server does not have this installed then it won't work however if you use it in a single player map - it does work just fine..
This is why I mentioned making a test map & using Worldedit to move stuff around.
The idea is once you got them just right - you can probably make a note of coords/spaces etc - then go online & build it there
FYI - there's a mod called VillageMarkerMod for liteloader.. this can show where your 'village' & 'breeder' borders are.
If you create a test world & use Worldedit to copy/paste/move each 'village'/breeder around, you can see how close you can get them without them registering any of the others. I used this when I created my Iron golem farm in the end
In the picture you see my iron farm on the farm (consists of 16 'spawn cells' - the 4 furthest ones are too far away to show the village sphere's) & a village breeder on the left - some distance away.
(You'll also may notice an old-style Enderman farm platform in the distance behind the lower cyan sphere - this is not affected by the iron farm in any way)
If I had the time & patience I could probably relocate the villagebreeder closer to the iron farm & it still won't register any of the spawn cells.
The only problem would be the 'foodfarms' in the tower in between the iron farm & breeder - The farmer villagers there MAY register the breeder as a village & try walking to it instead of actually farming although I guess by placing it [breeder] higher up - it should work
In theory I could even try & fit the breeder inbetween 4 of the iron farms cells since villages have a spherical range.. it MIGHT just be able to squeeze into that void between them
These food farms are approx 100 blocks away from both the iron farm & breeder & the farmers are not affected in anyway
(Sorry not @home to check on test world/server for exact distances)
I'm not sure where this '120 blocks away for a villager breeder' came from.. IIRC on a typical Iron farm the cells can be as close as ~70blocks & since these could also act as breeders then I would say '70 blocks' is more likely.
