MCPE-188221ambient_occlusion_exponent field in blocks.json does nothing in-game
In 1.21.50.24 preview, the field "ambient_occlusion_exponent" was introduced to blocks.json. This field was a replacement for the broken "brightness_gamma" field (see MCPE-167836).
However, this field is also broken as of 1.21.50.28. The field briefly worked in 1.21.50.25-1.20.50.26. This regression is likely related to MCPE-188216.
To Reproduce
- Import the sample pack: ambient_occlusion_exponent_tester.mcpack
which sets the following "ambient_occlusion_exponent" values:
- dirt: 1.0 (default)
- coarse_dirt: 100.0 (extremely dark)
- dirt_with_roots: 0.0 (no shading at all)
- sea_lantern: 1.0 (default)
- glowstone: 100.0 (extremely dark)
- shroomlight: 0.0 (no shading at all)
- Load a world with the sample pack applied.
- Place down dirt, coarse dirt, and rooted dirt.
- Observe the default 1.0 shading on all three blocks.
- Place down sea lantern, glowstone, and shroomlight.
- Observe the default 0.0 shading on all three blocks.

Expected Result
Setting an "ambient_occlusion_exponent" value on any block in blocks.json will configure the block's face dimming and ambient occlusion.
Observed Result
Setting an "ambient_occlusion_exponent" value in blocks.json has no effect on any block.

The ambient_occlusion_exponent field in blocks.json has been completely removed from all vanilla resources in 1.21.50.28, and the broken brightness_gamma field has returned for some blocks, despite being removed in 1.21.50.25.
This causes many block sets to be inconsistent with each other, despite the previous changes from 1.21.50.25 fixing this issue. It also caused a regression of MCPE-177356 and MCPE-184909.
This is a regression which blocks MCPE-187777 (inconsistent AO values for certain block sets). The table below takes MCPE-187777 into account and provides consistent values for all block IDs.

Expected Result
ambient_occlusion_exponent remains present in all vanilla resources on the same blocks as 1.21.50.25. brightness_gamma is not present.
Observed Result
ambient_occlusion_exponent field has vanished from all the vanilla resources, and the broken brightness_gamma field has returned.
Also, the hard-coded brightness_gamma values are back, and ambient_occlusion_exponent in a resource pack cannot overwrite them (MCPE-188221).

Replying to v-krbaj:
This report is not a duplicate of MCPE-187536. MCPE-187536 is specifically about light sources not working, which was an issue in 1.21.50.25 and 1.21.50.26 as well.
This report is about a new issue in 1.21.50.28, which is that the "ambient_occlusion_exponent" field does not work at all on any block.
Reopened; not a duplicate.
