I should probably update this first post sometime, but I'm too lazy. For now, I'm only updating the download link. If you want more up-to-date information on the mod, look at the latest page of the thread.
This is still very much a work in progress. At this point, most textures are simply tweaked, but stone, dirt, ore, and TNT are re-textured from scratch. Flowers, mushrooms, and saplings are all new. Generally, the world is less bright and happy-looking, and now the sort of place where you might be hunted by zombies.
This should work for creative, survival, or /indev/. Edit: Scratch that, it only works for /indev/ now. I'll put up the versions for creative and survival if I remember.
For survival mode, zombies and skeletons have been tweaked. No more bright blue clothing - zombies now wear brown, ragged clothes. Skeletons have been recolored slightly, and their faces have been tweaked to be more skull-like. Pigs are no longer quite such a bright pink. Rain and rain splashes are no longer bright blue. Armor has been made invisible because it looks silly.
For /indev/, all items have been tweaked, and tools and weapon have been redesigned. Tools of different materials now have their own unique looks. The inventory, crafting, and chest screens have been tweaked and recolored.
The HUD has been replaced.
I plan on changing spiders and creepers, turning cobblestone into stacked slabs of rock, and redesigning the armor for survival mode to something that actually looks like armor.
This may seem grayish and washed-out for some. I use monitor settings that turn up the contrast and saturation.
Open up the Minecraft folder in your Temp files (C:\Documents and Settings\[name]\Local Settings\Temp\www.minecraft.net for me), then open either Minecraft, Minecraft_creeper_test, or Minecraft_sneekpeek, for creative, survival, or /indev/ respectively. Open minecraft.jar. (You'll need to open it with an archiver program that can handle .jar files, such as WinRAR.)
Place plate.png in the folder "armor". Place items.png, inventory.png, icons.png, gui.png, crafting.png, and container.png in the folder "gui". Place zombie.png, pig.png, and skeleton.png in the folder "mob". All other files go straight in the main folder.
An example of tool variety, using axes:
Note that helmets are designed for characters with eyes at the 5th pixel from the bottom of the face, rather than the default 4th. If this is a problem for you, you could edit the helmets, or move your character's eyes. I prefer higher eyes, as it allows for more pleasing proportions in the helmets. Long faces are better than squashed faces.
I really like the iron ore, it would look good if the others were in the same style. Although, I don't like the natural stone much. I use it for building pretty much everything in creative, and my opinion is that it's too smooth. It doesn't look much like rock to me.
I think it may have to do with the host you used for the files, as they don't seem to be loading properly to save. May I suggest throwing all the images into a .zip or .rar and putting it on Mediafire, or something like that?
Edit: ... Or I could just wait for them to load all the way before saving them... That'd work, too...
You're right, it's the same for me. I guess something Notch did disagrees with my gradually-shaded shadow. It worked fine for mobs, so I suspect the culprit is the mini-block entities, which cast shadows. That doesn't explain why it won't load a save.
I'll remove shadow.png and re-upload.
Edit: The link in my previous post has been updated to the fixed version.
Yes, skeletons are invisible. The game also crashes when I try to craft sticks, and old survival gives me the "The game broke!" error.
I have no clue what might be causing this. The only changes I made since it worked were the shadow, the armor icons, and the hoes. Removing the shadow helped, but there are still problems, and changing the other two don't seem to help.
