📋 About This Mod
# Blocks Previewer ### Preview blocks before placing! !(https://raw.githubusercontent.com/tricube3/blockspreviewer/refs/heads/master/showcase1.webp) 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.) ## Showcase **TRANSPARENT mode** !(https://raw.githubusercontent.com/tricube3/blockspreviewer/refs/heads/master/showcase2.webp) **OUTLINE mode** !(https://cdn.modrinth.com/data/cached_images/5be02ed4c156f12a8ac41fd9fabf22d5746b8f73.png) **CONFIGS** !(https://cdn.modrinth.com/data/cached_images/b53de46462bc533b85ac636b799e283cc77e2ab6_0.webp) ## Dependencies (For versions >= 2.1.0) ### Fabric Dependencies Mod Menu is optional.
