the 28 report
When I was going to build a funny trampoline, I found a bright loophole
What I expected to happen was...:
There will be no cube height luminance hole, which can render the height normally.
What actually happened was...:
When you build a top level step at the top of your square column, you will find out that the height of the square can't be properly rendered and the unexpected brightness leaks are found, which also affects the third person perspective.
Try the demand material: any box (preferably without brightness), any step
Steps to Reproduce:
1. build 20 tall columns
2. put the top step on the top of the column
3. look below
Warning! This vulnerability happens occasionally, and some players may not see it, so this loophole is rare
