i have built a mob spawner with a 4 block column and 8 blocks out. inside i have put half slabs in a pattern to prevent spiders which only spawn in a 3x3x2 area.
the pattern is as such from the walls (o=Air x=Slab)
ooxooxoox oo xooxooxoo
the spaces in the middle represent the channel of water
the pattern is also mirrored
there are no 3x3x2 areas, could something else be causing this?

I also made further modifications and for a while it was working great but it seemed to have stopped a while back and still doesnt work for some reason. Mojang just really doesnt want us to use mob spawners i guess,
I’m currently on the 1.16.0.63 Beta and I’m having this issue. Here are my failed spawn tests in which spiders have spawned, but shouldn’t:
2 high w/trapdoors (for creeper farms) with every 2 spaces on X and Z covered with a slab. Spiders spawn.
I’ve done the same as above, but tried every other space instead of every 2. Spiders spawn.
I’ve used slabs and carpet to prevent spider spawning, it seems the 3x3x2 requirement isn’t accurate at the moment.
Thank you for your report!

Maybe they are spawning above the water channels? That looks like it is 4 wide and probably 2 tall.
