How do I make stones that a player can pick-up directly?

Basically a completely noob question that I can’t find the answer to anywhere. How can I place the “starter stones” that players first use to make a pick ax ect on my map? Rocks, trees, bushes ect are fine but I have no idea where to find the rocks you can interact with without a tool.

Search for SmallRocks in the content browser, then simply drag them into your foliage tool and assign their respective setting
