Slabify

Slabify scans the blocks registered in the game and creates a slab, wall or slice variant for each block it judges suitable. A new variant copies the attributes of its base block, so it takes on the same hardness, sound and light behaviour. Variants are created on the sawing table, where a Saw is needed to cut the base block; a block that is not compatible does not appear there.

Blocks that carry extra logic, such as a block entity, cannot be turned into variants, which excludes many machines such as furnaces and chests. Compatibility work across mods is still ongoing, so some blocks cause issues when first run. The mod comes with a configuration file, and any block that causes trouble can be added to the blacklist; blocks that are automatically blacklisted are still added to the blacklist when attempted, which is recommended for a clean setup. The option to load ForModdedBlocks is enabled by default, so variants are generated for modded blocks too.
