I recently converted a world which i ported block for block from the PC version, its a rather small farm. Within the farm 1 block and 1 block only has a light level of 7, its surrounded by a wall of glass, and it functions and works correctly within 4J's engine and PC's java version. However under the bedrock engine the light level is incorrectly being calculated when passing through the glass. When I replace the glass with solid blocks it functions as it should. This leads me to believe that when light is passing through transparent blocks its not being calculated as it should be, ie degrading.

Thank you for your report!

I'm not quite sure if this is what you are describing, but Glass shouldn't reduce light levels, and doesn't in Bedrock and Java.
Can you please add some more details to describe:
What you have built
What you expected to happen
What is actually happening
Please report back with the additional information, this ticket will reopen automatically when you reply.

Basically I'm making a farm similar to Nathan Ryan's crop farm as can be seen here https://www.youtube.com/watch?v=-BIrqPH4Jfk
The farm relies on a single plot of ground that will be at a light level 7, so that when a villager plants anything here it will pop out of the ground due to the light level being at 7 or lower, and it uses a pressure plate next to this farmland to force a block update to the farmland. The result is that the farmer walks over the pressure plate, plants the crop in farmland and while there may share food with a hungry villager, to which the farm intercepts and collects the food. As he leaves he steps off the pressure plate, and causes a block update, poping out the crop he just planted. He generally goes about his business harvesting more crops and will eventually notice the empty farmland and the process repeats.
Now I agree that glass is not supposed to reduce light levels, but light should also continue to degrade as normal. What I expect is happening is that light levels are actually continuing at exact same levels as before and after the glass, but without seeing actual levels its impossible to tell.
What I can say is that if I replace what he referee's to as the core in the video, with solid blocks the light level seems correct, and it functions correctly. However on 4J's console version and PC java version, they both work correctly with the glass core, only the bedrock engine seems to incorrectly handle light when dealing with transparent blocks.

Can you fix it to follow java version? This also effects microfarms which I also just tested and don't work without altering light levels.
Yes - this bug has been reported to our internal bug tracker for further testing and a fix. It is scheduled to be fixed in one of the future updates (no specific date can be provided).
