I need help adjust zombie sight(aggro) range please

I have the follow range to 100, but they don't see me any further than about 30 blocks and then chase me to 100 blocks and stop. I really really need them to see me from much further (100 blocks) for a game I am making.

They will chase for 100, but not see me for 100 to follow. I am using 1.14 and I already know generic.followrange,Base:100.0d, but it's not letting them aggro me. Thank you

Solution 1:

I believe thatvs due to mobs always freeze when they are 32 blocks away from players.

Solution 2:

This seems to be a bug, I created a report for it now: https://bugs.mojang.com/browse/MC-158075

Pathfinding of mobs is apparently disabled for performance reasons when the mob is outside of a 32 block radius. So a zombie farther away will not start pathfinding towards you if it's further away, even with a higher tracking range. It will, however, continue walking towards you when you move in and out of the radius.

I don't know any good workarounds for that. It might work to teleport the zombie towards the player and quickly back again, but you would have to wait until the zombie starts walking on its own.
