Tom’s Simple Storage: Extensions (formerly Tom's Trim Slab) is a Forge addon for Tom’s Simple Storage Mod that adds an Inventory Trim Slab variant to Minecraft 1.20.1. More block variants planned.

Download Release version 0.2.1 out now

Requires

Features

  • Added Slabs as functional Inventory Trim blocks, bottom top and stacked variants.
  • Slabs are Paintable with smart texture, light, and particle effect mirroring of paint-source block or slab.
  • Added Paint Kit function to use slab-type textures as paint-source.
  • Added Paint Kit function so block-type paint-source applied to Trim Slab finds slab-type textures to apply, and vice versa for slab-type paint-source, using common naming patterns.
  • Configurable paint override mappings for irregularly named slab and block equivalents.
  • Light emission, particle effects, and translucence are mirrored by painted Trim Slabs and Stacked Slabs.
  • Planned: floor/ceiling/wall/corner Inventory Cable variants.

Paint Hint: Copying a slab for slab targets and a full-block for full-block targets may give more reliable results.

Notes

  • This is an addon which depends on Tom’s Simple Storage Mod.
  • When no slab-type variant for a block-type paint-source is found, the mod will render a texture based on the paint-source.
  • Some unusual or custom block models may need manual config overrides to map slab-type textures to equivalent block-type textures.

Config

Server config file:

  • toms_extensions-server.toml

Legacy config files:

  • toms_trim_slab-server.toml
