On the voxelmap I see some blocks as black and it has been shown that these are only AC double slab blocks. Here is how it looks. Also if you destroy or jump on these blocks particles texture is not shown as it should be. What is wrong is that in every double_slab.json file in blockstate line:
“half=bottom,variant=false”…
is written 2 times but one of these should be:
“half=top,variant=false”…
Expect vanilla slab blocks, every AC double slab block has this problem and need to be fixed. It isn’t big issue but I think it is nice to fix that.
