UPDATE: in 1.21.50.28, the ambient_occlusion_exponent field was mistakenly removed from all vanilla resources. This is reported as MCPE-188216—until it is fixed, this bug report is blocked.
======================
In 1.21.50.25, many block IDs were given "ambient_occlusion_exponent" values (to fix MCPE-184909 and MCPE-177356).
However, a few blocks were given incorrect values, causing their shading to have an unintended look in-game.
Affected Block IDs
| Block ID | Intended Value | Current Value | Notes |
|---|---|---|---|
| cherry_leaves | 1.0 | 0.8 | Added post-Buzzy Bees - should match Java Edition brightness (1.0) |
| chiseled_nether_bricks | 1.0 | 0.8 | Added post-Buzzy Bees - should match Java Edition brightness (1.0) |
| cracked_nether_bricks | 1.0 | 0.8 | Added post-Buzzy Bees - should match Java Edition brightness (1.0) |
| mangrove_leaves | 1.0 | 0.8 | Added post-Buzzy Bees - should match Java Edition brightness (1.0) |
| nether_brick | 1.0 | 0.8 | Previously changed to use 1.0 brightness in 1.16 (Regression) - Applies to all nether bricks |
| nether_brick_double_slab | 1.0 | 0.8 | |
| nether_brick_fence | 1.0 | 0.8 | |
| nether_brick_slab | 1.0 | 0.8 | |
| nether_brick_stairs | 1.0 | 0.8 | |
| nether_brick_wall | 1.0 | 0.8 | |
| pale_oak_leaves | 1.0 | 0.8 | Added post-Buzzy Bees - should match Java Edition brightness (1.0) |
| red_nether_brick | 1.0 | 0.8 | |
| red_nether_brick_double_slab | 1.0 | 0.8 | |
| red_nether_brick_slab | 1.0 | 0.8 | |
| red_nether_brick_stairs | 1.0 | 0.8 | |
| red_nether_brick_wall | 1.0 | 0.8 | |
| sandstone_slab | 0.7 | 1.0 | Contrasts with all other sandstone blocks |
| snow | 1.0 | 0.45 | Contrasts with snowy grass side and powder snow (Regression of |
| snow_layer | 1.0 | 0.45 |
Sandstone Slab
Note: Red Sandstone Slab is already set correctly. Sandstone Double Slab is also set correctly. It is only the sandstone_slab ID which is incorrect.
Snow and Snow Layer
Note: The 0.45 values on snow and snow_layer are incorrect. Powder snow is correct. It is not possible to fix only the snowy grass block side without changing all grass block sides, so the snow must be changed instead.
Nether Bricks (Brighter than 1.16)
Expected Result
"ambient_occlusion_exponent" values are internally consistent. Blocks added post-Buzzy Bees should be consistent with Java Edition, unless they are part of an existing block set.
Observed Result
"ambient_occlusion_exponent" values are not consistent for specific block IDs. Some blocks added post-Buzzy Bees are not consistent with Java Edition.
A Note on Consistency
In the table in this bug report, consistency with other blocks was prioritized over parity with Java Edition. That is why the following blocks were not considered bugs:
- crying_obsidian: 2.0 matches obsidian
- respawn_anchor: 2.0 matches obsidian
- suspicious_sand: 0.55 matches sand
While the nether brick configuration of 0.8 is internally consistent, it also caused a regression back to the pre-1.16 Nether Bricks. This is why Nether Bricks were listed as a bug in the table, while Suspicious Sand was not.
