Description

Blocks Previewer

Preview blocks before placing!

showcase1

Ever placed a stair or piston the wrong way and had to break it again? Blocks Previewer lets you see how a block will be oriented before it’s placed, saving your time and frustration, especially useful for builders and redstoners.

This is a purely client-sided mod, and does not interact the server. Works similarly to Create’s placement preview, but for any block in Minecraft.

To open config for the mod, use the command /blockspreviewer or by using Mod Menu for Fabric or the built in (neo)Forge config menu.

Features

  • Controls

    • Press G to toggle preview
    • Hold H for a momentary preview

    (Both keys are fully configurable in the controls menu.)

  • Block filtering

    • Use J to switch between previewing:
      • All blocks
      • Only directional blocks (stairs, pistons, observers, etc.)
