Steps to reproduce: Get Small, Medium, Large Amethyst Buds and place them on an item frame or glowing item frame.
Expected results: The textures should be the same
Actual result: In an item frame, the Amethyst Buds get mirrored, making it different from the hand or inventory.
Confirmed. This is caused by the
item/amethyst_budmodel overriding thefixeddisplay of its parentitem/generatedin order to move it up slightly. The 180-degreerotationfromitem/generatedis not included and so is overridden to 0.This also causes amethyst buds and clusters to be mirrored when equipped in the head slot. No other items I found appeared to be affected in a similar way.
