This guide purely talks about how to change a current texture pack and not how to create a new one

The first step to making a texture pack is to get the necessary tools to create it. You will need to download the following:

• Any picture editor that can work on a pixel level (paint.net is a good free one)
  
• Software known as xnb_node

Put the files you downloaded from that link into an empty folder (make sure they are extracted) and then navigate to your main drive where your steam games are located. Go down into program files (x86) and to this path C:\Program Files (x86)\Steam\steamapps\common\Total Miner\Content
Once there copy the Textures folder and move it into the folder you put the other files in. Now you should have a folder with the previously downloaded files as well as the Textures folder. Finally make a new folder in this folder called new. Once this is done it should look like the image below and you can move to step #3

Press the win button + r to open the run menu. Once there type cmd and hit enter. When the command prompt window opens you will need to go to the folder you put the files in. To do this type . To find your path just click on the top of a file window where a location is shown and copy + paste that. Once you have the command prompt window in the right place type this command
From here it will run many lines of code and when its done it will have extracted all the png's from the old files. This leads to step #4.

Now choose a texture pack to modify, for sake of demonstraction i will use Original Spring HD, but any pack can be used. Keep in mind that HD textures can only be used on texture packs that were already HD.

Once you choose a pack to modify there are 3 important files to remember.

• tp files, these are the textures used for the blocks at close range
  
• tpi files, these are the textures used for items
  
• tp4 files, used for blocks at long range

The tp4 file is a lower resolution version of the tp used to render at long ranges and is needed for a pack to run correctly.

Once all the needed files are edited you can move to step #5

To repack the files to be used for the game we have to go to the cmd window again. Do all the steps needed to get a cmd window open that is in that same folder as early. Make a new folder called NewTextures and place it in the same folder the cmd window is open to. Now to pack the textures type this in This will take a while but will create a new set of files simmiler to the ones in the original Textures folder. Once this is all done you can move NewTextures to the Total Miner folder and change its name to Textures. This should now have a working texture pack in the game.

Once in the game select whatever texture pack you decided to replace and play with that. If you did everything right you should be able to play with a custom texture pack.

If you need more help I will shortly upload a video explaining how to do it on youtube here
