Projects/Tessera

Tessera replaces the vanilla block-breaking animation with a 3D voxel-shatter effect - entirely server-side, with no client mods or resource packs required.

Each voxel is a player head wearing a generated skin, which is what lets the effect render on a completely vanilla client. The skins are produced by MineSkin, and the block textures they are built from come out of MC Assets. Grid density is configurable, so servers can trade detail against performance.
