This is an unofficial backport of Constancy (formerly Continuity) for Forge 1.16.5, based on upstream commit 0595171.

Requirements

• Minecraft: 1.16.5
• Forge: 36.2.34 / 36.2.42
• Java: 64-bit Java 8
• Side: Client-side only (No Fabric or FFAPI required)

Features

• Supports Connected Textures (CTM), Overlays, Emissive textures, and custom block render layers.
• Compatible with native 1.16.5 resource packs (1.20+ blocks are not backported).
• Preserves vanilla rendering for moving/falling blocks to prevent visual bugs.
• Optional Integration: Compatible with Embeddium 0.3.18+mc1.16.5. The mod works fine on a plain Forge client without Embeddium.

Installation & Configuration

1. Drop the .jar file into your Forge 1.16.5 mods folder.
2. Open the config via Mods -> Constancy -> Config in-game (or edit config/continuity.json).
3. Two optional built-in resource packs ("Default Connected Textures" and "Glass Pane Culling Fix") can be enabled in the Resource Packs menu. Place third-party CTM packs above them.
