I've been using 1.7.10 for modding for a while and am just switching to 1.9 for dual wielding and other new features. But I don't understand most of the code or the "model" system, and I'm also having issues with the textures. If anyone can help with the basics of 1.9 like models, textures, items, blocks, tile entities, multi-sided block textures, connected textures and custom block models would all be helpful topics to get started with. Thanks.
