I know most of these are duplicates, but I just realised another one exists, and I couldn't find any posts of it, so I wanted to report it, and mention the others incase there's only one internal for all of these and it'd be better to have them all in a single ticket, since they're all the same bug of a block with transparent textures not having the cutout rendering applied.

The Galarica Cuff block renders transparent pixels of the texture as solid.

To list previously listed just so they're all in a single thing, there's Pixelmon Grass, Bridge Block, and the Doors and Trapdoors for Purple, Pink, Yellow, and Green Berry Wood.

Forwarding the transparency issues for the galarica cuff and the bridge block - the doors and trapdoors have been reported to Internal already; thank you~
