Fake Blocks Add-on

The Fake Blocks mod contains blocks that look like all normal blocks in Minecraft, but you can pass through them. You can think of many different uses for these blocks, building secret bases, unusual structures, or taunting your friends with traps. Everything is limited only by your imagination.
To create a fake block you need to create an empty block. After that any desired block is combined with the empty block. The empty block will take on the textures of the chosen block, but you can easily pass through it.
