Recently I have been designing a mob farm utilising the zombie reinforcement mechanic, which I have got mostly working there are just a few issues that I don't understand and can't find anywhere.
When I AFK at the farm I am positioned 40 blocks above the damage source (magma block) that triggers reinforcement spawning in 2 cardinal directions. When I am at this level spawn rates appear to significantly decrease, not stop just decrease.
Do mobs going through to nether side impact farm efficiency in any way, especially in relation to the afk distance?
The farm is fully working when I am closer to the damage source (10-20 blocks away) in previous testing before I had the designated afk spot, which cannot be changed easily. It is also not an issues with general reinforcement requirements as I am adamant I have those correct.
I thought it may be something to do with the spawn sphere and algorithm, however I'm not sure exactly how this works or if it even applies to reinforcement spawning. Or potentially simulation chunks or render distance may effect it but I'm also not sure. It is also important to note that the reinforcements spawning are locking onto villagers as their target when taking damage from magma blocks to spawn reinforcements in cardinal directions.
