You can download the resourcepack by clicking the link above and then clicking the download button. It is located in the top left of the file when you hover over it, or in the top right of your browser window when you click on the file to open it and see what's inside. Make sure you download the resourcepack to a file you can find again, so you can install it.

Installation
To load a resourcepack, follow this guide from the official Minecraft wiki: Tutorials/Loading a resource pack

You can find every mod, as well as the necessary mod loader, for download at the link above. As a reminder, you do not need to download every one of these mods—however, it is STRONGLY recommended you download More Player Models at the least.

Installation
To install the mods, you will need to open the same main folder as for installing resourcepacks.

For Windows
Press the Windows Key+R, and type "%appdata%" and hit enter (You can also input this into the search bar, located in the start menu). Open the folder named ".minecraft" and open the folder named "mods".

For Mac
Open Finder and navigate to "~/Library/Application Support/minecraft/mods". To access "~/Library/" on a Mac running MacOS 10.7 and above, switch to Finder, open the 'Go' Menu, and while holding down "⌥ Option", select 'Library'.

For Linux
Type "~/.minecraft/mods/" in your file manager's address bar or in the console (If it is not showing up, press the three dots in the corner and make sure that the "show hidden files" box has a check next to it, then try again).


After doing this, drag the mods you wish to download into the folder. You must put the forge file into this folder if you wish to download More Player Models or JourneyMap.

Once every mod is in the folder, double click the forge file. When the window pops up, leave "Install client" selected and press okay, then wait for it to finish. If you cannot get it to open, you likely will need to install Java. Java can be downloaded here. Ensure you pick the version suitable for your Operating System.

After forge is installed, click and open the "OptiFine" file, then press "Install". It will install without showing a progress bar, then pop up a window when it is complete after a few seconds. This will also require Java to do.


When you've finished installing those two mods, open up your minecraft launcher. Navigate to "Installations" at the top of the page. Click "New Installation", name it whatever you like, and then select the "version" drop down menu. Ensure your version is set to "release 1.18.2-forge-40.1.86". The click "Create". Finally, go back to "Play", select the installation you just created in the bottom left, and hit play. It is normal for the launch to take some time to reach the main menu.

Congratulations! You're ready for the Realm of Lithria.

When you are installing mods, always ensure the mod folder is clear of any mods that are incompatible. This would include mods made for the fabric mod loader, or mods for a version of minecraft that isn't 1.18.2. Otherwise, your game will crash on startup.

More Player Models
Press F12 and play around! You can configure your options, and how you look, here. Make sure you do so only as accurate to your character—turning yourself into mobs or giving yourself features like wings will get you in trouble with staff.

When deciding your height, treat every block as being a meter tall. While we treat each block as 5 feet on a side for combat to be accurate to D&D 5e, Minecraft is still built on the ideal scale of blocks being exactly one cubic meter in size. When designing for your character height, then, it only makes sense to treat blocks as just that—one meter tall.

For an accurate percentage, take your character's height in feet and inches, and convert it into a decimal. 5'6" would become 5.5 feet, for example. You can do this by dividing the inches by 12, then adding the feet. 6 inches divided by 12 is 0.5. 0.5 plus 5 is 5.5. Next, divide your newly found height by "6.08." This will give you your height percentage. In the case of 5.5, this results in "0.904," which rounds to 90%. If you set every percentage (head, torso, arms, and legs) to 90%, you will now accurately be 5'6" tall!

When dealing with the width of body parts, the choice is yours. Feel free to make your character lanky, portly, or anything in between; the percentages above are just for semi-accurate heights.

Should you not wish to do the math yourself, you can find a rough chart below.



Optifine
Optifine offers many options under "Video Settings," and is especially useful to those who wish to have a farther render distance, or reduce settings which can cause them to lag. It helps most on mid-range machines, rather than those which run very poorly. It also offers some options for visual enhancements, such as blending glass blocks together so they dont have a grid-like pattern.


JourneyMap
All of JourneyMap's features and functions are bound to keys, which can be changed in the "Controls" menu. The best way to learn this mod is to use it, and playing with the settings until the minimap and larger map are comfortable to use and designed to your preference.
