The bug

The end gateway beam texture is rendered rotated 180 degrees rotated from what is expected. This applies for both the inner and outer beam.

How to reproduce

1. Download and apply the attached resource pack
2. Look at the end gateway beam
3. Compare to the texture file inside the resource pack

Expected results

Arrow pointing up, blue on left, yellow on right.

Actual results

Arrow pointing down, yellow on left, blue on right.

How to fix

Change the texture mapping so that it matches the texture file more accurately.
