Vertical Slabs Compat
With Vertical Slabs Compat installed, every block that has a slab in another mod also gets a vertical slab variant from Quark.
What it does
The mod fills compatibility gaps between Quark's vertical slabs and other blocks. For each block that has a slab, it adds a matching vertical slab, and it skips any block that already has one. Moonlight Lib is required, and Quark is optional, because the mod can also run on its own without Quark installed.
Files exist for Fabric, Forge and NeoForge, covering 1.19.1 – 1.21.1 across four release versions. The mod runs on the client and the server, so both sides need it. It is released under All rights reserved and is not open source.
Key features
Automatic slab variants
Blocks that have a slab receive a vertical slab variant without manual setup or configuration.
Duplicate protection
Variants that already exist are not registered a second time, so existing content is left alone.
Works without Quark
The compatibility layer runs alongside Quark, but it does not require Quark to be present to function.
