this is how the item is rendered in the book

and this in the ground

The problem is the translucent textures, for some reason the rendered used in the book doesn't use the correct render type.
This is my ISTER: https://github.com/grillo78/BeyCraft/blob/master/src/main/java/com/grillo78/beycraft/items/render/BeyItemStackRendererTileEntity.java
