Block outlines are partially transparent and thicker.
Blocks that lose support (e.g. torches, carpet, scaffolding, etc.) make breaking sounds and particles.
Blocks with an X model, such as saplings and flowers, always have the same texture applied left to right (the front and back face per pixel are not the same).
Blocks broken by pistons emit particles.[167]
Breaking (not mining) particles start as the shape of the block and are colored based on its darkest face.
More blocks can support general support-needing blocks.[note 34]
