I've been wanting to do custom blocks for some time now but there are no good tutorials for it! And if there is a tutorial, it's from 1.3... Can anyone here explain how to do it? Show me some code, or a least link me to a decent tutorial? I would be very grateful! Also, you can link me to open source mods that do custom rendering. 1.5 tutorials would be nice, since all texture methods changed. Thank you very much.
