GitHub - Larsonix/BlockBench-Transparency-Plugin: Blockbench plugin that fixes visibility of objects inside transparent containers (glass, windows, etc.). Auto-detects transparent textures and adjusts render order so inner elements show through.

A Blockbench plugin that fixes the visibility of objects inside transparent containers (glass, windows, etc.).

The Problem

Blockbench's WebGL renderer has a limitation where objects inside transparent cubes are not visible - they get hidden by the transparent surface due to depth sorting issues.

The Solution

This plugin adjusts the render order of elements so that inner objects render before transparent containers, making them visible through the glass.

Features

Auto-detects transparent textures - Scans pixel alpha values to identify semi-transparent elements
Name-based detection - Recognizes common naming patterns: glass, window, crystal, ice, water, liquid, glow, inner, contents, fill
Geometry detection - Automatically detects if cubes are physically inside transparent containers
Enabled by default - Works automatically when installed
Toggle on/off - Easy to enable/disable from the View menu

Installation

Download transparency_fix.js
In Blockbench: File > Plugins > Load Plugin from File
Select the downloaded file

Usage

The plugin is enabled by default. To toggle:

View > Toggle Transparency Fix

Compatibility

Blockbench 4.0.0 and above
Works on both Desktop and Web versions

Notes

This plugin only adjusts render order - it does not modify your model
Some visual artifacts on transparent faces are a WebGL limitation and cannot be fixed
Models will render correctly in actual game engines (Minecraft, Hytale, etc.)

Version

2.1.0
