Translucency

Translucency is a concept very closely related to transparency. Blocks, items, entities and other game elements said to be translucent allow for vision to pass through them partially, but not fully.
== Examples of translucent objects ==
=== Blocks ===
==== ====
All translucent blocks use the rendertype_translucent core shader, with the exception of tripwire, which uses rendertype_tripwire.

===== Blocks that are not translucent, even though they'd be expected to =====
Water cauldrons, despite containing water, render this water as completely opaque. While it was rendered translucent as expected in prior versions, this seems to be inconsistent and possibly hardware-dependent, and when it fully stopped is currently unknown. Its opacity is also a parity issue, as cauldron water appears translucent as expected . This persists to the present day.
Similarly, while tripwire itself is translucent, the region of tripwire which connects to a tripwire hook is not. This causes the region of tripwire attached to the tripwire hook to appear much darker than the rest of it.
