I'm a huge fan of the Just Create SMP series and the modpack. Here's the description of that pack:

The official modpack of the Just Create SMP!

This modpack is designed to be light - featuring Create: Post Production update and a few minor quality of life mods. No fluff, no additional mobs, structures, tech or world generation, just create!

This pack will get a few updates in future as certain mods become available on this version (Steam & Rails mainly!), but the aim is to keep it as close to vanilla+ create as possible.

All mods in this pack belong to thier respective creators - without whom this pack would not be possible!

I've added some additional mods to make my life easier in the relatively short amount of time I have to play games, though.

I've built this to be a smaller pack to allow for older PC usage. This runs fine on a complete rotten potato of a HP with a Ryzen 1300, a 2 or 4 GB graphics card, and 16 GB of RAM. I've set the modpack to use 10 GB of RAM.
