silicate and regalite dust where to get those, ruby and sapphire i gues you get from destroying planets
if there somewhere more info let me know

You get silicate from destroying moons and regalite from destroying cold asteroids (temps must be below zero). Check the catalogue for that info. I think all the new crafting stuff explains where to find it.

last thing can bleuprints also be stolen in a attack planet?
