I just realized that in all my time within the Nether I've never had a mob spawn in my netherwart farm. Now, while this would make sense after my farm was complete, because of the netherwart being on the block, it took my quite a bit of time to fill up all my blocks with netherwart. And in all that time (3-5 hours) I never got a single zombie pigman in my farm.

Can Zombie Pigmen spawn on soulsand?

Mobs definitely do spawn on soul sand, the solid block requirement is for the block graphically, and soul sand graphically is a solid block (no transparency).

I did test it with a glass enclosed room with a soul sand floor and zombie pigmen did spawn inside.



Nothing can, as it's not a solid block (it is only 7/8ths the height of a normal block).

    Wow, +1 for block size... I didn't know that!

    I am sorry, while the height of soulsand is indeed 7/8ths of a normal block, that height is only used for collision calculation (to simulate the player sinking in a bit). The block itself is not transparent and is drawn like a full block. That causes it to be a valid block to spawn mobs on.

    They DO spawn on soul sand.
