Hello, it's me again! I bet you probably hate seeing my name pop up by now.

This is a vertical slab.

It plays nicely with horizontal slabs.

It plays nicely with adjacent vertical slabs that have the same orientation.

Unfortunately, if you place an adjacent vertical slab in the opposing orientation, things go a bit wrong.

There's nothing wrong with the orientation, this vertical slab placed on top renders just fine.

The slab doesn't seem to care about an adjacent horizontal slab...

Placing this vertical slab next to the original one resolved the issue...

But wait, this is strange too! Now there's a corner shaped vertical slab where there's meant to be a flat one! It's also missing some of its geometry which shows the world behind it as though the block were invisible.

(If the corner shaped slab is meant to be a way to create "vertical" stairs, I think that's awesome but you should really make it a separate item)

I know its a bit tricky, so i should exactly sho, where you place the slab and the orientation from your character.

Same as issue #16

Hello, I agree that #16 and the last photo look at the same, but are you sure that the rest of the issue (slab appearing as a half-slab only taking up a quarter of the total block space) is the same?

Fixed in 1.16.4-0.2
