Lepton
by eltrutlikes
Lepton adds stairs, slabs, walls, buttons and pressure plates for the vanilla block types that lack them, and it is built for NeoForge 1.21.1.
What it does
Many default vanilla blocks come without a full set of matching variants. Lepton fills those gaps by adding stairs, slabs and walls for blocks that have none, along with buttons and pressure plates for polished stone types, so a block set can be completed in one place.
Wood stairs, slabs and walls follow the vanilla wood types, and quartz brick also receives stairs, slabs and walls. When Quark is installed, Lepton adds vertical slabs through automatic compatibility. The project focuses on porting some features that Quark once offered.
Lepton requires Differentiate to run. It is a Client and server mod, so the server and every player need it. Files are published for NeoForge only, for 1.21.1, with 3.1.0 as the latest file, released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license and not open source. Source code and an issue tracker are public.
