Mechanical Essentials is a light pack with mods that are built off of vanilla mechanics and made something special with them, or smaller quality of life mods(and rats) totaling out to 31 mods.
The main highlights are Create, T-construct, Immersive portals and Rats.
We wanted something modded but still close enough to vanilla that it didn't feel like too much and after playing with create for a while we built this!

Does this work with Optifine?
Yes, however you need to download Optifine 1.16.5 G7 because G8 will crash your game

Is this pack server friendly?
Mostly, I marked all the mods that we don't include on our server, and I recommend you remove them as some will crash your servers.
