The artifacts are in the planet the same color they are (except for the white one)
EDIT: i am playing the map now, and i have to say, this is one of the few maps that have a lot of potential. but i think you should add something noticible to your v3. like the black hole, the nodes are a great touch (and needed on some planets) but thats like the frosting on the cake. try to add something that seprerates your map from others. one idea is that you can go inside the buildings on earth, and also maker it easir to get out of that crater/tunnel thing on mars, you know, the slope where it goes down?
this is a remarkable map that is very optimized, yet has great detail. this is something you dont see often.
keep working on v3, you did great on optimsazations, i know since my pc sucks and it rus with 20 fps, and to be honest, i seen maps less then a megabyte and my pc lags more on it. i suggegest you add something new, since there is not much else to improve.
good job!
I disagree about the fps. Out of all of the SB maps I've played on this is on the low end for fps, only because it is one of the higher quality ones.
