Looks and rotation

One texture, a texture per face, or a model, and blocks that turn like logs or furnaces.

Looks

Use one of these:

One texture

ruby_block:
  type: block
  texture: ruby_block.png

Per face

ruby_log:
  type: block
  textures:
    top: ruby_log_top.png     # both ends, unless bottom is given too
    side: ruby_log.png
  rotation: axis

Face keys: all, side, top, bottom, or each face on its own: up, down, north, south, east, west. The most specific one wins, so all plus north gives every face the same texture except north. particle sets the breaking particles.

Model

ruby_lamp_block:
  type: block
  model: ruby_lamp.json     # its textures are found next to it

For textures that join up with their neighbours, see Connected textures.

Rotation

rotation · text

• axis: turns like a log, along the axis of the face you clicked.
• horizontal: the front faces the player, like a furnace.
• facing: like horizontal, but it can also face up or down when you look steeply up or down, like an observer.

Each direction uses its own slot and look: an axis block uses 3, a horizontal one 4 and a facing one 6 (see How many blocks).
