JEIRender

JEIRender is a small client-side compatibility utility for JEI.

This mod fixes a specific rendering problem in the JEI bookmark list. Some JEI ingredients are not normal Minecraft item stacks. They may be virtual ingredients, wrapped ingredients, or special integration entries provided by other mods. When JEI tries to render these entries through its batch rendering path, they can display incorrectly in the bookmark list.

JEIRender allows specific JEI ingredient UIDs to be excluded from JEI batch rendering. Excluded ingredients are rendered through an alternate fallback path instead. This only affects how selected entries are drawn in the JEI bookmark list.

Example Use Case

A known example is Ars Énergistique, an addon that integrates Ars Nouveau with Applied Energistics 2.

Ars Énergistique provides ME Source storage integration for Ars Nouveau Source. In affected setups, the Source-related JEI bookmark entry can be represented internally as an Applied Energistics 2 wrapped generic stack instead of a normal Minecraft item stack. When this wrapped generic stack is rendered through JEI's batch renderer, it may appear incorrectly or fail to render properly in the JEI bookmark list.

JEIRender fixes this type of issue by allowing that problematic JEI ingredient UID to be placed in a blacklist, causing it to bypass JEI batch rendering.

Features

• Fixes incorrect rendering for selected JEI bookmark entries.
• Prevents configured JEI ingredient UIDs from using JEI batch rendering.
• Uses a fallback rendering path for blacklisted ingredients.
• Includes a configurable UID blacklist.
• Includes an optional render UID log to help identify problematic JEI entries.
• Client-side only.
• Does not add items, blocks, recipes, world generation, mobs, or gameplay mechanics.
• Does not change JEI recipes or ingredient registration.
• Intended for modpack compatibility and visual fixes.

Configuration

The mod provides a client configuration file with:

• blacklist: JEI ingredient UIDs that should not use JEI batch rendering.
• render_log: When enabled, logs JEI ingredient UIDs while the ingredient list is rendered. This is useful for finding the correct UID to add to the blacklist.

Who Needs This?

This mod is mainly useful for modpacks that use JEI together with mods that register virtual, wrapped, or non-standard JEI ingredients.

If a JEI bookmark entry renders incorrectly, but the item or ingredient itself works normally in gameplay, JEIRender can be used as a client-side visual compatibility fix.
