Got a weird one. I've used this mod on my PC and my old Mac. Got a new Mac and installed KSP and this mod (plus a few others), but for some reason the textures all come up grey, except the metallic one looks correct. All other functions work, just no textures. Checked my folders and everything is where it's supposed to be, even reinstalled mod to be sure. Anyone have any ideas? Again, running on OSX.
