What is RenderJS?

Same as in the FTB Skies 2 1.22.0 guide

The pack ships RenderJS version 2101.2.4, installed as the NeoForge build (renderjs-neoforge-2101.2.4.jar). It has been in the pack since this version or earlier.[1]

Unverified The available sources don't describe what RenderJS does, who it is meant for, or where it fits in the pack's progression. There is no in-jar guidebook, no platform listing and no quest data for it, so this guide makes no claims about its features. Nothing here shows it on the ATM Star path, and no quests are confirmed to involve it.

Items and blocks

We can't match this mod to the pack's item list: it registers as renderjs, and the pack's recipe dump has nothing under that name. That means we found nothing, not that the mod adds nothing. Search the item browser
