Using Cocricot 9minecraft Blocks
Placing and Combining Props
All 24 entries in the Cocricot 9minecraft catalog are blocks, and they are meant to be placed in the world like any other decorative block. The wiki's blocks section is the place to look when you want to know what a given prop looks like before you commit it to a build.
Many of the items come in families, which is useful for consistent detailing. The Antique Book appears as a closed book, an open book, an open book with glasses, a pile, and a line, so you can scatter matching reading material across a desk or shelf. The Antique Globe and Antique Celestial Globe pair naturally as a study or library centerpiece. Lighting follows the same idea: the Antique Light Head, Antique Deck Marine Lamp, Antique Bulk Head Marine Lamp, and Antique Classic Wall Bracket let you keep one fixture style throughout a room.
Doors are another family. The Aluminum Door, Aluminum Tall Door, Aluminum One Glass Door, and Aluminum One Glass Tall Door share a material and differ in height and glazing, so you can choose based on the opening you have built.
Since the mod is decorative only, there are no special mechanics to master. Treat the blocks as a palette: pick a theme, then use the matching variants to keep your build coherent.
