Seeking materials in USSes

[iain666]

So, I'm after some Proto Radiolic Alloys.

I know I want to look in High Grade Emissions Detected USSes in Boom systems.

If I find a couple of those and they have a different material does that indicate that there's been a roll for my instance that precludes what I'm after so I should move on (or re-log) or will that make no difference at all? Do we know the answer to that question?

I know I could also trawl mission boards, finding this specific material isn't the question - USS spawning is.

ETA - now three in this system and all Proto Heat Radiators, I'm leaning towards a single roll when you enter the island...

I was doing the same thing just this evening! Anarchy boom systems are supposedly good, the High Grade Emissions spawn in deep space. I went to Bunda, a system quite close to Founders World.

There's no need to re-log at all, you'll find them in the one instance. Just keep scanning high grade. If you're lucky you'll get get 2-3 units of each in a single drop.

Next system USS 1 had the radiolic alloys and proto light alloys. USS 2 only had the light alloys. Nothing conclusive but it's time for bed. I'll keep looking for patterns tomorrow.

The rare materials spawn in systems depending on their economy and current state. So, if you've gotten them once in a system, hang around there for a while to get some HGE wakes.
Also, I think this thread might be better suited in the Engineering section, as it's engineering materials? Might be more people there knowing exactly which kind of systems the different materials spawn in.
