The texture isn't transparent. It's there, it just isn't rotated. If I also add a y rotation, it still rotates on the y axis, but still no rotation on the x axis.
The image in the spoiler shows what it looks like right now (should've added it in the original post, just forgot). Since UP and DOWN are both true and the rest are false, the only connections should be on the top and bottom. Instead, both of the connectors show up in the front, overlapping each other.
