Put the summary of the bug you're having here

What I expected to happen was...:
In addition to thinking that they had already removed it from the game ... what should happen is that you could not see through the blocks without having to do some kind of trick, just ... walking through the caves

What actually happened was...:
that when walking through the caves you can see through the blocks when going from one chunck to another, but I have only been able to verify that mobs can be seen, I do not know if caves because I do not look down hehe

Steps to Reproduce:
1. walk quietly on f5 of the back wall and bring the camera to the cave walls, it also works in first person, even when approaching the cave walls
2. ... i do not know  what else to say... hehehe
3. ... same as two... hehehehehehe...
