Mobs light transition is not smooth compared to blocks

Mobs light transition is not smooth compared to blocks.
The lighting method applied to the mobs is not as smooth as the lighting method used by the blocks.

For a more detailed comparison of biological lighting, please refer to the following comment.

Can confirm.

Can also confirm. Why was this issue resolved as "Incomplete"?

This is most notably when summoning shulkers with light above, and which probably due to this shulker boxes are affected as well (MC-231102).

Here's a more detailed comparison of smooth lighting on mobs. Both pictures on the left is how it looks right now on with smooth lighting on, and the pictures on the right is how it looks with the smooth light transition applied.

The difference is very subtle, but if you watch closely you can notice it. Both images on the right were taken using sodium 1.16 which fixes entity smooth light (no longer works on 1.17). I think there's plenty of info in the ticket now?

Hello, can this be reconsidered? I'm inclined to believe that the WAI resolution is a little mistake here, as the screenshots provided probably weren't enough to demonstrate how noticeable this issue really is. This is a bug that affects almost every entity in the game, including players.

Some of the related issues like MC-231102 & MC-1531 are already being triaged, where the latter covers this issue about paintings and item frames, which are in fact entities. This was fixable in 1.16 (as i mentioned, sodium did at some point) but after the 1.17 rendering changes this cannot be fixed even by mods in some reliable manner, due to the shader code using integer vector types, limiting the value range to the usual 15 light levels.

The differences can be seen here, with players:

And also mobs, like skeletons:

Hopefully this is enough to show that this is genuinely an issue.
