Translations:Chisel/12/en
From Vintage Story Wiki
This is an upgrade to the aforementioned microblock chiselling, which allows to combine up to 4 different kind of blocks to use together in one. After creating a multi-material chiselled block, the procedure to work with it actually stays the same as above, enabling the player to remove or add individual pixels. However, if different types of blocks have been combined, using the 'F' key mode on that block with a chisel in hand will allow the player to choose which of these blocks they want to use to add pixels.
