[1.15.2] Strange behavior with non cube blocks.

[ken2020]

I don't really know how to describe it in words, so I attached an image instead.

 

Can someone please tell me what is going on?

What's happening is that minecraft thinks the bottom face of your block occupies the entire bottom face of the cube, so it doesn't need to draw the blocks underneath your block.

You need to either

1) set the VoxelShape for your block correctly;

For example see here:

or alternatively

2) give your block the notSolid() property
