Before we begin...
This is not the BEST guide to having the BEST looking game. This is just a LIST of mods that will make your game look better and not a step by step modding process. The guide can be confusing for beginners because of all of the textures, meshes, and in which order you install them. We recommend you fiddle around with some of these mods first to understand the basics.
If you read the Essentials guide (as you should have) it says that you should get an ENB. If you haven't gotten an ENB or read the ENB page, you should do that now before moving on.
Mods for NPCs and characters are located in the Waifu and Husbando guides and are NOT in this one.
This might seem out of place, but we also recommend you to check out Hodilton's channel. He showcases many mods and ENBs. but what seperates him from every other person who does this is that his rig is AMAZING and it shows in his videos. He has one of the BEST looking modded Skyrim games out there and his videos will help find you new mods and give you inspiration to make your game look as good as his!
