Sand effect makes powder particles decorated with varying colors to make them look a taad more realistic, but only when you place them after setting it to this mode
what does sand effect do?
I feel like I made these like all the time
FP is ephemeral, Spi. You'll get a longer-lasting one yet. This is a pretty nice powder-painting.
Why does this get to FP but my awesome air base doesn't?
good for nuke detonation tests
