Ok, so i was using Slime Finder (A minecraft App). I Went to a slime chunk that was on my island, placed a spawner, and still no slimes D:

Is it placed below a 40 block height from the void? Or within the Void? And is it set To slime?

 

Level 13

 

And yes

 

I'l come have a peak at it a bit later, busy atm, Perhaps two heads will be better than one.

 

G2G, Do /warp epic Then Fly Under The island, you will Find the spawner. Make Improvements if you can, If it Still doesnt work, Then u can place the spawner in a chest @ /warp epic, or just place it at the same place it was
Thanks for the help

 

Does it need light? can't remember if slimes are only light level >x

 

Slimes don't need light, but they are the only aggressive mobs that spawn in light.
