Hi All
But the visual effects as shown by the pictures published when core mining was introduced seemed to be extremely dependent on the users graphics system and settings.
Ahaa!...now that's an interesting point @ RJay.

I've just recently been doing some core mining to test the new 15.02 'update'.
At the moment I'm personally not seeing much change from the pre version. I'm finding (as before) when using the PWA there's a fair amount of 'glowing' asteroids in the immediate proximity to the hot spot centre. Very rarely do these contain true core materials, usually they contain either sub surface or surface minerals or metals.
Continuous pulsing and moving gradually out in various directions then might display very bright highlighted asteroids. Most of these bright highlighted asteroids still don't (in my experience) contain core materials,
Unless their form is roughly speaking,' pear shaped'.
I'm still finding that if I select a hot spot , say for example Monazite, and manage to find an asteroid that
has core materials, that asteroid might contain Monazite, but it might not. It could contain some other material, say for example Painite, Serendibite or perhaps Rhodplumsite. ect.

This seems a bit illogical to me, but hey!...that's how this feature works, so again, I just accept it.

...it's a bit 'carrot on a stick' gameplay but there you go.

I
generally get a fair percentage of the chosen core material, but not always, so it can be a bit frustrating sometimes looking to mine a specific material.
Hmm, I wonder if particular graphics settings does have any bearing on the actual workings of this feature?
It would be helpful if somebody on the development team could answer this question perhaps...please!

(I use a Nvidia GPU for this game, just as a side note).
