MC-238573Custom block models are incorrectly lit at low light levels
When using custom models for blocks (such as dripstone) the game will sometimes incorrectly render some faces of the model fully bright.
It happens when the block is on the edge between 1 and 0 block/sky light.
I don't think this should be classified as invalid because even tough it's only visible on non-vanilla block models this is a problem with the rendering engine itself rather than the texturepack.
Steps To Reproduce
- Download and enable this resource pack bright_kelp.zip
- Go into the ocean
- Find kelp
- Observe the kelp becoming bright on the transition from 1 to 0 skylight
Alternatively
- Download and enable the resource pack Enhanced Dripstone v1.1.zip
- Place down a torch
- Dig a 13 block long tunnel away from the torch (as shown in attachment below)
- Place a barrier block on the 12th block and a dripstone on top of it
- Observe the bug
Expected Behavior
These blocks wouldn't be fully lit at very low light levels
Observed Behavior
They are.

The bright spots appear exclusively when light level goes between 1 and 0 which is consistent with that issue.
The report summary and decription is just wrong. It has nothing to do with y levels or powers of 16. You can easily see it by just changing the water depth.

I can confirm but this is invalid (modified game)
Turn off the resource pack. If the issue persists, I suggest recreating the issue without the resource pack. If its the pack, its probably broken or designed that way.
