SlashSlabs

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): it stopped at eu.pb4.polymer.blocks.api.PolymerTexturedBlock, a class from a jar nested inside the mod; Kiln does not unpack nested jars yet.

In the author's words

Server-side half-slab steps on every one-block terrain rise, so players walk the world without jumping — no client mod needed.

Scanned on 4 November 2026 against Kiln 0.2.0, file slashslabs-0.2.1+mc26.3-fabric.jar. The scan reads the mod's classes; it does not run them.
