Vertical Slabs Everywhere

Vertical Slabs Everywhere

A NeoForge 1.21.1 mod that adds a Quark-style vertical slab for every slab any installed mod registers — wood, stone, brick, any material. Drop it into a pack and every modded slab gains a vertical variant, with no per-mod configuration.

How it works

At load time the mod scans the block registry for slabs and registers a matching vertical slab for each one, using Moonlight Lib's late-registration hook (the same mechanism Every Compat uses) so the whole modded registry is visible before scanning.

For each generated slab:

• The block extends Quark's vertical slab block, so placement, rotation, doubling, waterlogging, and collision behave exactly like Quark's own vertical slabs.
• Blockstates and models are generated at runtime. Models inherit from the parent slab's own model, so textures resolve when models bake — this works even for slabs that are themselves generated dynamically by other mods (Every Compat, StoneZone). Slab models with nonstandard texture keys are handled by a key-synonym resolver.
• Loot tables (double drops two), 3:3 crafting recipes both ways, optional 1:1 stonecutter recipes, mining-tool tags copied from the parent, and tag entries under quark:vertical_slab, c:vertical_slabs, and c:slabs.
• Display names are derived from the parent and follow Quark's naming convention ("Oak Vertical Slab" style) in every language the parent provides.

No duplicates

If any other mod already provides a vertical slab for a material — Quark itself, Every Compat's wood types, StoneZone's stone types, anything ending in _vertical_slab — this mod skips that material. Installed alongside those mods it fills only the gaps they leave.

minecraft: namespace blocks from backport mods

Genuine vanilla slabs are skipped (Quark covers them), but the check is against the actual vanilla block list of the running Minecraft version — not the namespace. Mods that register their blocks under minecraft: for save-compat reasons (e.g. Vanilla Backport's cinnabar, sulfur, and resin brick slabs) are treated like any other modded blocks and get vertical slabs automatically.

Compatibility with the original Vertical Slabs Compat

Blocks register under the v_slab_compat namespace with the same id pattern as MehVahdJukaar's Vertical Slabs Compat (last released for 1.20.1): v_slab_compat:<parent_namespace>/<name>_vertical_slab. Worlds and structure files built with the original resolve seamlessly.

This is an independent clean-room implementation — none of the original's code or assets were used — and it is not affiliated with or endorsed by MehVahdJukaar. If the official v_slab_compat mod is ever installed alongside this one, this mod detects it and registers nothing, so the two can never conflict.

One niche limitation: worlds that ran the original without Quark used v_slab_compat:<vanilla>_vertical_slab ids for vanilla materials; this mod requires Quark, which provides vanilla vertical slabs under its own ids, so those specific ids are not recreated.
