After a long while (Couple months) away from Galciv, I finally had occasion to grab another of its DLC- I was very happy with the parts from Mega Events, so I decided that I would get the Ship Builder pack (as I spend most of my GC3 time in the ship editor.)
HOWEVER, either the latest patch or the DLC has introduced horrific visual artifacts to all parts- as a modeller (strictly on an amateur/hobbyist level) it appears that many parts have inverted normals or other lighting-related issues. as an example, this is a picture of a ship I built some time ago:

and this is what it looks like now:

just LOOK at those Bolloxed shadowmaps! and, of course, how the Secondary color on most of those parts is now black thanks to inverted normals making the render engine think the surface points the other way!
this has made the game essentially unplayable- I can't stand seeing all the nice models I use (and the ones in the stock game!) turning into half-black smears for more than a few minutes.
