What is Vertical Slabs Mod 1.20.5 – 1.19.4 in Minecraft?

Vertical slabs, also known as “upside-down slabs” or “double slabs”, are a variant of regular slabs that can be placed on the sides of blocks, rather than just the top or bottom. However, this can be used to create walls, columns, and other structures that use half-blocks in a vertical orientation. Furthermore, some mod like Quarks adds the functionality of vertical slabs to the game which allows players to use them in their builds.

Guide to add Vertical Slabs Compat Mod with Fabric:

Fabric is a Mod Loader as well as a toolchain (Java library) for installing and creating Minecraft mods for Release Versions and Snapshots. It’s an alternative to Forge API, which is still a stepping stone for enhancing gameplay through community-created mods. Fabric API is newer and lightweight compared to Forge, but it’s quickly updated with newer Minecraft versions and its mode base/quantity is increasing gradually. Fabric is also lightweight however it is still lacking behind in terms of compatibility while simultaneously running a different set of mods.

For player:

You can install Mods using Fabric Loader & API which comes with the automatic installer which creates profiles in Minecraft Launcher. Once you run the game once using newly created Launcher profile, then open %appdata%/.Minecraft and drop your favorite mod (.jar extension file) into the mods directory.

For developers:

If you are familiar with Java, there are extensive mod development guides and tools available to simplify the process. For example; Fabric Loom, Yarn, tiny-remapper, and Engima (for deobfuscation of Java bytecode). You can head over to the official wiki for more details.

Note: Fabric and Forge API mods cannot run together and will probably crash your Minecraft. Keep a copy of your save games before you experiment with the mods.

How to Install Vertical Slabs Compat Mod with Minecraft Forge:

Keep one thing in your mind that Forge Mods require Minecraft Forge API and Fabric Mod needs Fabric API.
If your modification requires Forge and it’s not released for the required version then you can not play that on that version.
Generally, the Forge version takes a bit of time to release but it is justified.
Since the installation process is fairly simple which will need a few basic steps.
First of all, you need to download Minecraft Forge API (Basic API Tool).
Secondly, you are advised to create a Minecraft Forge Profile.
Moving forward, you are required to download the modification you want to use in Minecraft from above or below.
Interestingly, after running the game, the modification will start showing on Forge Profile.
Keep in mind, that if the tool is not showing on Forge Profile then try restarting Minecraft.
Mostly, restarting Minecraft works 90 out of 100 times and mod start showing.
Abracadabra, now the magical beings, and play your favorite mod in Minecraft.

    Just an FYI. Trying to run in MC 1.20.1 version, I received this error once I downloaded Moonlight.

    The game crashed whilst initializing game
    Error: java.lang.RuntimeException: Could not execute entrypoint stage ‘main’ due to errors, provided by ‘v_slab_compat’!
