Hello, I have a Question. I have programmer a Mod successfully and it works fine. The only Problem is that it can't load the Blocks.png / Items.png File. I put them in: /bin/minecraft /eclipse/minecraft/bin It loads a Picture, but not that witch i want. It's a White Block / Item with a Black Point on it. I watch some tutorials on YouTube but no one of these can help me! I hope that you can help me Guys! Bye
