Description

The Antiblocks already included with RGB Blocks are amazing, even working wonderfully with shader bloom!
I was wondering if it would be possible to include a border-less version of anti-blocks?
Would be an amazing addition - and if it would be possible to see on 1.20.1 that would be doubly appreciated albeit not a requirement by any means.

Ideas on how to implement it

Best way most likely is removing the border from the already existing anti-block texture and adding it as a new block

Worst case I would be fine digging around in the code and potentially PR'ing it myself
