What is CosmeTech?
CosmeTech is a pack with a few big tech mods and thousands of building blocks, most pertaining to the vanilla feel. Immersive Engineering and Immersive Petroleum are the main technology mods, accompanied by Create (and Create: Crafts & Additions) for those who desire a more vanilla-oriented automation solution. You are now able to automate ore mining, ore duplication, ore processing, machine part manufacturing, fuel refinement, power generation, crafting, storage, and much more. In addition, Tinkers' Construct has also been thrown in to give you a more immersive tool-customization option.
Where does the Cosmetic aspect come into play?
The two biggest and most noteworthy cosmetic mods are Chipped and Chisels & Bits. Chipped serves as quite a vanilla-styled chisel mod. Adding thousands of new block variants to all existing ones, you are sure to literally never run out of building ideas. Finally, Chisels & Bits provides what can be a bit less of a vanilla solution to custom decorations. With the ability to configure all 4,096 (thanks calculator) 3-D pixels within a block, you are sure to have endless possibilities.
Is there anything else?
I have thrown in many, many smaller mods to aid with everything from exploration to, you guessed it, more building! Repurposed Structures, Small Ships, and Astikor Carts allow you to enhance your vanilla exploration experience, while Construction Wand, Cycle Paintings, Decorative Blocks, Engineer's Decor, Farmer's Delight, Framed Blocks, Gauges and Switches, Macaw's Paintings, Mr. Crayfish's Furniture Mod, Path Under Gates, Storage Drawers, Supplementaries, Torch Slabs, Waystones, and MANY more provide more specific decoration options (and many of them have other purposes too!).
I have put a bit of time into this pack, so I hope you enjoy it. Please feel free to give feedback in the comments, as I am open to updating this pack until it is tuned perfectly to what it is aiming towards.
