What are some good Minecraft mods for a server on 1.12.2?
There are a lot of mods that do different things and want to achieve certain feels. Mods that make things harder on survival, mods that make more things renewable, mods that let you automate production chains like a factory, mods that only change cosmetics of things, MAGICK, vehicles, guns, and so on.
What do you want out of Minecraft that it doesn’t already do? For me immersion is enjoying how I look, so Armourer’s Workshop and Cosmetic Armor Reworked are absolute musts. If Chisels and Bits is going to be in there, I’ll make sure Extra Bit Manipulation is in there too so there’s a tool that’s not only more like how LittleTiles works, but more cosmetic options for my avatar too. And you know what, LittleTiles is just oomph. You can make good looking doors from it and change climbable surfaces with it too. Saves needing stuff like Secret Rooms and Malisis Doors. it’s good stuff.
BetterFPS (improves the game’s performance)
foamFIX (improves performance, fixes some minor stuff AND prevents the game from crashing most of the time, instead it will tell you that something stopped working and ask you if you want to quit to title instead of straight up closing the game)
Just Enough Items/JEI (a must if you want to use mods that add content, provides recipees for ALL items, modded and unmodded as well as a list for said items, since sometimes they don’t appear in the creative menu)
Quark (adds a shitload of vanilla friendly content and adds a lot of features that should arguably be in the game already, including some features that where added on later updates, world generation, colored wood, etc. It even has quick stacking to nearby chests Terraria-style)
Quick Leaf Decay (good for any mod that adds custom biomes, prevents lag from irregular tree’s leaves spawning too far away from the trunk)
Redstone Flux (a main module for any productivity mod, you’ll want this just in case even if you won’t use productivity mods)
Roguelike Dungeons (adds a bunch of random structures that can generate around the world, from simple rock formations to entire dungeons that reach the bottom of the world and even new houses for villagers)
Thermal Foundation, Expansion and Dynamics (adds new materials and tools for all the materials (wooden shears, diamond bows, iron fishing rods, copper swords, etc) as well as machinery for transporting, processing of resources, energy distribution, etc. A must have for almost any long-term modpack, it also allows for re-growing ores on chunks from before the mod was installed)
Worley Caves (changes cave generation to be more continuous and extreme, making many interconnecting shafts instead of just randomly dabbed tunnels like in vanilla)
Xaeros Minimap (lightweight minimap which can be used for placing waypoints and even auto-calculate nether to overworld distance ratios)
VanillaFix (another performance mod, i don’t fully remember what it does but it helps)
Traverse (lightweight world generation improvements, just adds more variety to world generation in the form of biomes, trees and other structures without adding any items or blocks)
