Go to the start menu, and where the search bar is type "%appdata%". It should take you to the "roaming" folder. From there you should find a folder called ".minecraft". In that folder, go to "bin". Then, open Minecraft.jar with winrar. Find the file named terrain.png, and then edit that with photoshop or gimp (or any program that can maintain the transparency) and save it.
This is how I would do it, anyway. I run Windows 7. If you plan on doing this multiple times, I suggest making a shortcut to the folder and placing it on your desktop or something. It does revert back to the original texture pack whenever Minecraft updates. Hope this helps :biggrin.gif:
Paint doesn't maintain transparency, so the black boxes are the transparent areas that paint automatically filled in for ya. You have to use gimp or photoshop (or similar program) because they keep the transparency.
GIMP is free, google it and download. Hope this helps ya.
Since I'm bored and waiting on my own post response somewhere else, and I like writing simple step by steps, I figured I'd elaborate:
1. Download And Install Winrar from http://rarsoft.com/
2. Open Appdata Folder:Click START, and in the RUN box (Search Files and Folders for Vista and 7) type %AppData% (Or you can open Windows Explorer and type in C:\Users\YOURUSERNAME\AppData\Roaming\.minecraft\bin)
3. Double click on .minecraft
4. Double click on BIN
5. Right click on Minecraft.jar and choose OPEN WITH
6. Choose WinRar
7. Find the terrain.png file.
8. Drag it from Winrar to your Desktop (Or a folder you'll remember)
9. Open it in GIMP or Photoshop. DO NOT use Paint.
10. Edit to your hearts content.
11. If you don't still have the minecraft.jar file open in WinRar, repeat steps 1 - 6
12. Drag your edited terrain.png file FROM your desktop (Or the folder you'll remember) INTO WinRar
13. Close Winrar. :smile.gif:
14. Enjoy your new textures
Who cares? It's still a thread with some useful info, which turns up in Google search results.
Exactly! helped me out, thx for the tip about GIMP save me hours of playing in paint for nothing.
Side note: In minecraft.jar under different directories can be found all PNG files for the game Ex. Terrain folder holds sun.png & moon.png
