Since last night I can no longer change my ships material in the customizing window. My ships also have a metallic texture now instead of the ones normally applied by default. I updated my drivers and reseted my video options but nothing seems to fix this. Anyone else happen to see this?
Check to see if you have one of the visual effect shields equipped. Sounds like you have the MACO shield on. Right click it in the ship screen and choose disable visuals.
If that's not it, the bug could be related to the ship colouring problem. Select one of the preset styles in the left of the ship tailor, and then you should be able to customize everything afterwards.
