Shadow blocks

by hii029916

Shadow blocks adds translucent blocks in four shades of black, from 25% to fully black, for building shadowed scenes on Forge 1.20.1.

ForgeClient and serverAll rights reserved1.20.1

What it does

The mod adds blocks with transparency in several darkness levels: 25% black, 50% black, 75% black and full black. Builders can mix them to shape shadows, silhouettes and dim interiors, and a few transparent blocks serve as world-building pieces in a structure.

The blocks are meant for creative building rather than survival progression, so they suit map makers and build projects. The author plans to add more colors in a later update, but none are included in the current release.

Forge is the only loader covered. Shadow blocks runs on client and server, so the server and every player need it. The files target 1.20.1 only, and the mod is released under All rights reserved, so it is not open source.

Key features

  1. Transparent blocks

    Blocks with partial transparency let light and background show through the structure.

  2. Four darkness levels

    Separate blocks at 25%, 50% and 75% black, plus a fully black block, give graded shading.

  3. Shadow building pieces

    A small set of transparent blocks is included for world-building shapes and silhouettes.

  4. Creative focus

    The blocks are aimed at creative building and are not part of a survival progression.

Use cases

Shaded scenes

Builders can layer the darkness levels to make soft shadows across floors, walls and ceilings.

Silhouettes

The fully black block and the translucent blocks can outline shapes against the surrounding structure.

Who it’s for: Map makers and creative builders who want shading in their structures. Survival players without a creative focus are not the target audience.
