Immersive Petroleum is known as an addon in the wider Immersive Engineering ecosystem. Addons can bring additional industrial ideas, but compatibility must be checked separately from the base mod.
What is an Immersive Engineering addon?
An addon builds on the concepts or systems of another mod. Unlike the base mod itself, an addon is an additional installation that may depend on a particular version of Immersive Engineering and a compatible game loader.
Where Immersive Petroleum fits in
Immersive Petroleum is associated with industrial petroleum processing and infrastructure. Treat it as a separate project: do not assume that its supported Minecraft versions or loader options are identical to those of Immersive Engineering.
Check addon requirements carefully
Read the addon project’s current compatibility information, including game version, loader and any dependent mods. Install the base mod and the addon only when their requirements align; unsupported combinations can fail to load or break existing worlds.
Expand gradually
Try your core factory first, then introduce one addon at a time. Keep a backup of your world before changing a modpack, and consult the addon’s own documentation for machine recipes and feature differences.
For release-specific details, consult the published Immersive Engineering files before installing or updating your game.
