What it is
A material is a rule that picks a block, or picks nothing. It can look at how deep a block is, its height, a density, or the content of a nearby network point.

Good to know
Nothing is not air
When a material picks nothing, a Material Queue moves on to its next material. Choosing air is a real answer and stops the queue.
Solid and empty
A constant material doesn't check whether the block is solid. Use Material by Solidity when solid ground and empty space need different blocks.
