Ok, I changed my code to match what you said. The textures still do not load in. Also, in the preload in the main class, the "GenerationHandler" cannot be resolved to a type in the "GameRegistry.registerWorldGenerator(new GenerationHandler() ,2);".
Ah, I changed GenerationHandler to GrayOre. I can't seem to find any in the world. Also, help for the textures please? Also, I'm very sorry about this. I know it must be a pain for you.

GenerationHandler: Are you even importing it?
When I press ctrl shift o on the keyboard when the GenerationHandler can't be resolved as a type, it says 0 imports added.
That would be because you renamed it to GreyOre.
Note that they are in different packages, I did not upload them in folders.
